I am a retired privileged white guy, and I also don't know a lot of folks who buy used cars. The average car on the road today is about eleven years old, and very few of my friends drive cars that have been on the road longer than ten years. This means that my personal knowledge is very highly skewed toward the new end of the car fleet. I suspect that many of the cars in the older half of the fleet are third-hand, bought from friends, or hand-me-downs. It will take another decade before we see EVs filter down to this level, and the first-generation EVs (early Nissan Leafs and BMW i3, pre-2015 Teslas) may not make it at all because of battery life. This means that we won't really know the shape of the used-EV curve until perhaps 2036. Â It might be most accurate to say I've spent time in both worlds. I understand both what it's like to do dirty, dangerous, exhausting labor and what it's like to be intellectually stressed by challenging problems from the comfort of an air-conditioned office. I've had friends who were penniless and friends who socialized exclusively in wealthy circles. This was not according to any ambitious plan; I just met them along the way. I've met good people from all walks of life - but they approach financial decisions in wildly different ways. Seeing how cars are advertised to poor people is fascinating. The total focus is on monthly payments and encouraging them to buy the most expensive vehicles their credit score will tolerate. That dealers focus so heavily on this suggests to me that it works. Actually watching poor people make purchasing decisions is also fascinating. A lack of self control combined with a compulsion to keep up with others and a complete lack of knowledge leaves them susceptible to the aforementioned advertising. I see plenty of new, fast cars parked at low-end housing. They aren't new luxury cars - these people clearly can't afford BMWs - but they are the fastest, most ostentatious vehicles the owner can make the payment on - at least, until said owner makes a single mistake and their financial house of cards collapses. To wit: there are plenty of Honda Civic Type R's, full-size pickup trucks, and full-size SUVs parked at low-end housing. These people also invest considerable sums in modifying their vehicles. Lowered suspension kits, expensive audio systems, enormous chrome rims, and fancy paint jobs are ubiquitous in poor neighborhoods. Cigarettes, dip, drugs, alcohol, energy drinks, and convenience foods are also ubiquitous. The same people dropping enormous sums on their cars, swag, conveniences, and pleasures live in unsafe housing, have no emergency fund, invest nothing in their education, spend little time honing their skills, and do not read. In short, they have neither interest in bettering themselves nor a plan for the future. They value immediate pleasure over long-term gain and, without exception, obtain exactly what they value. It's been my experience that "poor" people have access to resources; they just *appear* poor because they squander those resources. Thus, I don't think there will be any problem financing EVs for "poor" people. Given that the TCO for EVs will be lower than that for ICEs, I don't even think EVs will cut into their smoking, dipping, drinking, drug use, energy drinks, or convenience foods. If anything, the stability of electricity prices will leave them less susceptible to financial disasters. Concerns about EV prices also forget that today's crop of EVs are mostly high-performance, luxury vehicles marketed to the affluent. You could save a lot of money by reducing that to an econobox with just enough power and range to get around town. The only reason it hasn't been done is that more lucrative markets are available. That will change soon enough. 3 1 2 Quote Share this post Link to post Share on other sites

Jay McKinsey + 1,490 June 14, 2021 Except that shorter range batteries will be LFP Under strict test conditions, commercially available lithium cells of both types were repeatedly discharged and charged from 0% to 100%. The result? According to the paper, “The LFP cells exhibit substantially longer cycle life spans under the examined conditions.” The tests were performed at the Sandia National Laboratories as “part of a broader effort to determine and characterize the safety and reliability of commercial Li-ion cells.” The study examined the influence of temperature, depth of discharge (DOD), and discharge current on the long-term degradation of the commercial cells. LFP chemistry is superior compared to NMC All cells were charged and discharged at a 0.5 C rate or the amount of discharge that will deplete the full capacity of a battery in two hours. In the graphical representation shown (taken from the Journal’s 2020 technical paper), you can easily see that the discharge capacity retention for the LFP lithium battery (blue data points) far exceeded the NMC battery retention (indicated by the black data points) for each round of charge/discharge cycling. The graph indicates that the NMC degrades almost twice as quickly as the LFP, showing the superior overall performance of the LFP cells. The testing showed LFPs had a better RTE (round trip efficiency) than NMCs, calculated by dividing the discharge energy by the charge energy. This calculation shows that the LFP is the more efficient, economical choice. Lithium nickel cobalt aluminum oxide battery, or NCA, was also a part of this experiment and performed similar or worse than NMC. We do not focus on NCA in this article as it is not mainstream in the commercial use of lithium batteries for Material Handling, mainly due to safety and cost issues. Both NMC and NCA cells demonstrated strong dependence on the depth of discharge, with greater sensitivity to full SOC range cycling compared to LFP cells. LFP cells had the highest cycle lifetime across all conditions, but this performance gap was reduced when cells were compared according to the discharge energy throughput. https://onecharge.biz/blog/lfp-lithium-batteries-live-longer-than-nmc/ 1 1 Quote Share this post Link to post Share on other sites
footeab@yahoo.com + 2,190 June 14, 2021 (edited) Yes, in climates where it does not freeze, LFP will dominate. It is already fait a compli at this point. All boats and RV's have already switched to LFP. Every house could be on LFP today. My Ebike I switched to LFP when the NiMh died. Was easy to do. PS: If you want LFP cycle rates, you can go with Carbon Foam lead acid. Only drawback of those cells is their overall efficiency. Much heavier... comes down to manufacturing cost, but they can be used where it freezes at least. Edited June 14, 2021 by footeab@yahoo.com 1 1 Quote Share this post Link to post Share on other sites

I'm interested to see what happens with battery tech in the next 2-4 years. Absolutely nothing in next 2-->4 years is on the horizon from what I can tell or even 5-->10 years. There hasn't been anything new in the last 5-->10 years. Only "***new*** thing is that LFP increased energy density by 50% by going to rigid aluminum cases instead of spongy plastic truly making them viable for cars now. And their cells can be made MUCH larger much more cheaply than NMC. Of course they can't be charged below freezing so... I'm still hoping for aluminum iron phosphate ion batteries as anyone should be able to make them. 3.2V/cell = perfect for 12V systems and shouldn't have freezing problems. Aluminum ion still has the potential for far greater energy density than any Lithium chemistry. 1 Quote Share this post Link to post Share on other sites

Note that it does not use nickel or cobalt. Lithium and graphite are not much of a constraint on production, plenty of both to be had. Copper is a minor component of the battery. It is mostly in the motor and wiring. As a constraint, copper will be the same for any EV regardless of the battery.

Without scalabilty the batteries remain expensive and rare.   I specifically mentioned LFP, but I called them phosphorus iron batteries. They aren't a possible vehicle battery for most cases however because they weigh too much for each unit of electricity they store. They have enormous potential for grid scale storage however because their cost per unit of electricity stored is really outstanding.   I agree that graphite isn't a construction constraint. Lithium, in theory isn't, but because the installed capacity to mine and refine it is tiny compared to what will be required, it will suffer from a series of supply shortages lasting a few years each, followed by overproduction for a few years, as the supply and demand chain works in a herky jerky fashion. Copper isn't a component of the batteries themselves, but it is, as you and I both pointed out absolutely critical for wiring. This is important, because it's a major new use of copper which existing ICE vehicles do not require. Rhe weight of copper required for each EV clocks in somewhere around 80 - 100 lbs, and combined with the numberof EV's likely to be produced suggests that the world demand for copper will roughly double in the next 20 years or so. That is not nearly as great an increase as it is for other materials, but it's against a backdrop of a world copper mining industry which is already struggling to increase production at record high copper prices.  With respect to the solid state batteries, IMHO they aren't a massive change from current options. They are still constructed with the same basic materials (lithium, graphite, nickel, cobalt) but with alterations to the electrolyte. This will be an improvement, but I don't think large enough to qualify as a major breakthrough.  1 Quote Share this post Link to post Share on other sites

By analysing the parts of their product which they leave out, we can also make some important observations This announcement qualifies as 'lab breakthrough' if it is true, and the article explicitly notes it as such (note that there are a range of statements in the article which are projections, not yet based on full scale data) 2024 is the earliest noted start for any production of any type: From the article "“We will bring the coin cell to market first. It recharges in less than a minute, and it has three times the energy than with lithium,” the Barcaldine product said.  This is the 'pilot production' stage which I mentioned. The 'final product' they indicate a desire to make  is battery fuel cells for automobiles, but they fully realize that they can't jump from a successful lab experiment to a mass produced half ton product, so they are planning to start on a much smaller scale - in fact they are not even seeking contacts or data about automotive applications at this time - also from the article:  "GMG has not locked down a supply deal with a major manufacturer or manufacturing facility. “We are not tied in to big brands yet, but this could go into an Apple iPhone and charge it in seconds,” Nicol confirmed." This is the stage of the process I labeled pilot scale production, and per my previous comment: " it takes 1-2 years to convince a company/country/organization to build some of them on a pilot scale (not yet commercial, or being sold only to get some market exposure) " They specifically acknowledge that they haven't inked a deal with a company which can actually make their pilot production start. They have carefully made a statement such that this sounds like an advantage "we are not tied to big brands yet" but in fact it's a problem, and this statement is a speculative one, acknowledging that they have to sign a contract with someone who has the capital to finance the pilot production. They handwave this stage of the process away, possibly out of an excess of optimism, possibly as a careful marketing strategy, or possibly out of genuine ignorance of how commercial production deals are organized, but my experience with investing in, and operating wit technology and manufacturing suggests that it will take them 1-2 years to actually make this deal, then another 1-2 years before it yields the coin type cells for small consumer products. Their later statement in the article "GMG plans to bring graphene aluminum-ion coin cells to market late this year or early next year, with automotive pouch cells planned to roll out in early 2024." Is not supported by the previous ones indicating that they have no commitment from a partner to manufacture anything - this is merely a hypothetical 'best case' scenario, where an agreement for pilot production of coin cells commences immediately, then pilot production of automotive cells starts immediately after the coin cells prove themselves. That's a commendable concept, but it won't happen that way in reality. The reason they made the announcement is clear however: 'Listed on the TSX Venture exchange in Canada, GMG hooked itself in to UQ’s graphene aluminum-ion battery technology by supplying the university with graphene." So GMG is a publicly listed company, seeking to boost it's stock prices (the Toronto stock exchange has notoriously lax rules for reporting, and stock manipulation) which is fine - you can buy/invest in it right now! But there is one thing the article doesn't so much as hint at, and the author, and GMG really hope you don't either, and that is the price of the cells. Reading between the lines, it's obvious they aren't ready for automotive use yet, but in small electronic devices the price of the battery is a much smaller portion of the cost of the overall device, and the need for more storage capacity or charging speed is obvious.  QED: Good lab data. There may be a product that is suitable for small electronic devices in a couple of years. It's entirely unclear if the product even has potential for scaling to automotive or utility battery scale uses at all. The company GMG is hoping to hype itself through articles such as this, in hopes that insiders can sell stock and make a lot of money, or that they can ink a deal with a major partner to sell batteries to and get capital from, or sell the company and it's patents to them outright (or some combination of the 3) These are all good and healthy parts of the development of a new technology, and yet another sign that there are real opportunities in battery developments in the mid term (5-10 years) but this is not in the short term advance that is about to take over the market.  1 Quote Share this post Link to post Share on other sites

You clearly described the traditional technology pipeline - and I appreciate the clarity you provided. I'm not convinced it will apply to the future though. Silicon Valley in general and Tesla in particular saw the traditional process, realized there was an advantage to be had in compressing it, and succeeded in doing so. For at least two decades - possibly longer - they've been rolling out advanced technologies more quickly than their competitors thought possible. It started with software, but they're now applying it to hardware. Sandy Munroe's company has been tearing down vehicles and selling reports on them; he also offers some free insight on his Youtube channel, Munroe Live. His analysis of Tesla over the years has consistently followed this pattern: First teardown: Tesla is 1-2 decades behind competitors. Second teardown: Tesla has mastered the traditional technologies. Third teardown: Tesla has commercialized technologies that no one even knew was in the R&D pipeline. The first we're hearing of these technologies is when we take apart production vehicles. Tesla's technological journey - from decades behind to beyond the bleeding edge - occurs in <4 years. I.e. Much of that time is consumed by mastering the old technologies, which means Tesla is going from concept to commercialization in < 3 years. Depending on the technology, they may even be doing it in months. How is this possible? It's the wartime effort you alluded to in a previous post. World War II proved that new tech could be commercialized quickly. One need only assemble world-class people, give them appropriate resources, and describe a clear goal. Tesla has recreated that wartime process. More generally, all of Silicon Valley realized that speed creates an overwhelming advantage and built their culture around it. They teach their people that the best way to learn is to fail fast and often. The companies following the wartime model are the companies taking over traditional industries. One by one, they're identifying easy industries and tearing into the market share. There will be progressively less room for traditional R&D processes to operate.  Edited June 21, 2021 by BenFranklin'sSpectacles Removed an accidental emoji. 2 1 Quote Share this post Link to post Share on other sites

I agree that to get to the point of scalable manufacturing for the auto industry this will take many years, and that's if it works as they claim. Then again as @BenFranklin'sSpectacles says, get with a manufacturer such as Tesla and it may be a whole lot quicker than we think. Quote Share this post Link to post Share on other sites

One by one, they're identifying easy industries and tearing into the market share. There will be progressively less room for traditional R&D processes to operate.  Tesla is a good example of a company doing it right, but they aren't 'breaking the model' with respect to technological uptake, and neither is silicon valley in general. Their 'catchup' phase was fast, and that would be expected. I tend to agree with you on Tesla's ability to go from 'unknown' to 'commercial' in 3 years. However Tesla is NOT taking ideas straight from the lab into full scale mass production in 3 years. They are taking ideas from the lab into pilot scale production in 3 years. That's still damn impressive, and they are doing it consistently, which is even more impressive. My 'tech develoment' timeline assumes no screwups, and Tesla is doing a great job of reducing/eliminating screwups. That takes a LOT of work. Another thing they are doing, in the vast majority of cases, they have set up their pilot production in such a way that it is a miniature version of full scale production, or that it can be easily scaled up. They are also 'pre-selling' items they don't yet have in full scale commercial production, then back filling the production capacity later. The only reason they can do this is because there is high demand for their products, and they have consistently been able to convert planned projects into actual products, which gives the general public confidence that they can count on them.   This is why in my 'timeline of innovation' I purposely left out any years/time between pilot production and going full scale. IF they are doing it right (and Tesla is) there isn't any real 'gap between the two - only the logistical effort it takes to move from small scale pilot production to large scale production. A final thing that Tesla is doing is making it more or less painless for their customers. If you are 'one of the first' to get a new Tesla product and it doesn't work, they will repair, replace or fix it for you more or less at no cost. This additionally inspires people to be willing to take a chance on something they wouldn't normally do. This is part of the phase that I mentioned in 'preparing the destribution and sales network' Because Tesla at this point is more or less constantly innovating, internally they see this as just 'the way it is' but other companies will have to work hard to develop this mentality (some will not, and will fail - I'd never lay a finger on a GMC electric car for example) 3 Quote Share this post Link to post Share on other sites

Jay McKinsey + 1,490 June 23, 2021 US Government Says Electric Vehicles Cost 40% Less To Maintain In its latest study, the Office of Energy Efficiency and Renewable Energy says, “The estimated scheduled maintenance cost for a light-duty battery-electric vehicle (BEV) totals 6.1 cents per mile, while a conventional internal combustion engine vehicle (ICEV) totals 10.1 cents per mile. A BEV lacks an ICEV’s engine oil, timing belt, oxygen sensor, spark plugs and more, and the maintenance costs associated with them.” https://cleantechnica.com/2021/06/22/its-official-us-government-says-electric-vehicles-cost-40-less-to-maintain/ 1 3 Quote Share this post Link to post Share on other sites

Slow drivers, driving the minimum speed, are really not safe in my opinion. It should be used for suburbs and crossing highways. If it can maintain a sixty miles per hour speed, that would be ok on highways, but not freeways. In and around Houston that little car would be a death trap. 4-8 lane freeways are the arteries you can’t escape. Once you’ve taken the off ramp it does get a little safer since the speed drops and there are more traffic lights. Can autonomous tech make driving safe? Kind of like herd immunity, only if the majority have it and use it. And of course it has to work like advertised. Quote Share this post Link to post Share on other sites
