Let's not get side-tracked from the main issue. Although that is a standard tactic used by some climate alarmists. My principal point is that you continue to incorrectly generalize from NCM batteries to "all EV batteries". Using current trends, I expect that there will be a lot more EVs with LFP than with NCM, because Chinese and Europeans simply do not need the range. High-end cars will cost more and will use NCM. This all assumes that some other better chemistry does not come into production in the next ten years. GM keeps pushing their "Ultium" battery design, which somehow magically uses about half the lithium, cobalt, and nickel, apparently replacing them with fairy dust. Your argument about a lithium shortage is much more credible, so you should probably focus on it instead of cobalt. You can also legitimately argue that copper can become a bottleneck. But for Nickel and cobalt, higher priced NCM will shift consumers to cars with LFP. The lithium shortage will not be in mining, but in refining. The final refining stage for nearly all battery lithium done in China. unless someone invests a serious amount of capital into lithium refining and some into more mining, your shortage scenario will be compounded by a Chinese lithium OPEC-style monopoly.

No need to worry, if the Prez gets his way, and atmospheric CO2 falls low enough, agricultural productivity will decline precipitously, famines will cause depopulation (which many climate activists are calling for as the ultimate solution), and the problem will solve itself. Amazing how easy it is to solve problems when there are fewer mouths to feed, that one answer seems to fix everything. Of course there would be no problems at all without any population.....hmm. I better get on the phone to the White House and offer advice to the Big Guy. 1 Quote Share this post Link to post Share on other sites

That will probably not change very much, for the reasons above. That translates going forward into a shortage of cobalt and high prices. Also shortages of lithium, copper, and palladium. Penn State team develops thermally modulated LFP battery; fast-charging, inexpensive, long-life for mass-market EVs 19 January 2021 A team of Penn State engineers has demonstrated a thermally modulated lithium iron phosphate (LFP) battery to offer an adequate cruise range per charge that is extendable by a 10-minute recharge in all climates, essentially guaranteeing EVs that are free of range anxiety. Such a thermally modulated LFP battery—designed to operate at a working temperature around 60 °C in any ambient condition—could support a well-rounded solution for mass-market EVs, the researchers said. Furthermore, they found that the limited working time at the high temperature presents an opportunity to use graphite of low surface areas, thereby prospectively prolonging the EV lifespan to greater than two million miles. A paper on their work is published in Nature Energy. We developed a pretty clever battery for mass-market electric vehicles with cost parity with combustion engine vehicles. There is no more range anxiety and this battery is affordable. —Professor Chao-Yang Wang, corresponding author The researchers said that the key to long-life and rapid recharging is the battery’s ability to heat up quickly to 60 ˚C for charge and discharge, and then cool down when the battery is not working. The very fast charge allows us to downsize the battery without incurring range anxiety. —Professor Wang The battery uses a self-heating approach previously developed in Wang’s center. The self-heating battery uses a thin nickel foil with one end attached to the negative terminal and the other extending outside the cell to create a third terminal. Once electrons flow it rapidly heats up the nickel foil through resistance heating and warm the inside of the battery. Once the battery’s internal temperature is 60 ˚C, the switch opens and the battery is ready for rapid charge or discharge Wang’s team modeled this battery using existing technologies and innovative approaches. They suggest that with this self-heating method, they can use low-cost materials for the battery’s cathode and anode and a safe, low-voltage electrolyte. The cathode is thermally stable, lithium iron phosphate, which does not contain any of the expensive and critical materials such as cobalt. The anode is made of very large particle graphite, a safe, light and inexpensive material. Because of the self-heating, the researchers said they do not have to worry about uneven deposition of lithium on the anode, which can cause lithium dendrites that are dangerous. This battery has reduced weight, volume and cost. I am very happy that we finally found a battery that will benefit the mainstream consumer mass market. —Professor Wang According to Wang, these smaller batteries can produce a large amount of power upon heating—40 kWh and 300 kW of power. An electric vehicle with this battery could go from zero to 60 miles per hour in 3 seconds and would drive like a Porsche, he said. Other Penn State researchers working on this project were Xiao-Guang Yang, assistant research professor of mechanical engineering, and Teng Liu, doctoral student in mechanical engineering. The US Department of Energy’s Office of Energy Efficiency and Renewable Energy and the William E Diefenderfer Endowment supported this research. https://www.greencarcongress.com/2021/01/20210119-psu.html Edited April 23, 2021 by Jay McKinsey Quote Share this post Link to post Share on other sites
footeab@yahoo.com + 2,194 April 23, 2021 (edited) 18 hours ago, Dan Clemmensen said: You can also charge an LFP all the way to 100% repeatedly without reducing battery life, Not true at all. LFP and NMC do NOT like to be charged to 100% and why they MUST have a battery management system. If you charge them full up you will kill them and why many fires were started in early days of lithium. There is zero battery chemistry existing that I am aware of that you can use 100% of its capacity without reducing battery life massively. Lithium do not like to be fully charged, but can go very low without much damage. Lead acid, nickel metal hydride, or nickel cadmium MUST be fully charged at some point or all of the time to top balance them, but do not like to go low or be held low at all and why they suck. There are exceptions when the anode is changed out to Graphite and then they can stay low indefinitely, but not exactly all that low as the voltage rolls off fast. LFP/NMC: Rule of thumb baring any advancements/cost cutting in the Anode of course so... "100%" discharge you get ~ 2000->4000 cycles depending on number of cells in said configuration. 50% discharge jumps it up past 8000 30% ~ 12,000 15% or less = 20,000+ NMC is nearly identical to LFP as a rule of thumb NMg is roughly as low as 1000 cycles, some claim 2000 cycles on a single cell. Roughly half that of LFP/NMC Now throw in that the batteries lose capacity per year just sitting in Lithium chemistries, so use it or lose it. Just in case anyone thinks there will be museum pieces which will still drive in 100 years simply because the battery has not been used as you were eyeing that 20,000 cycles....

Uh, backwards actually. Old LFP had a 120Wh/kg and new LFP are sitting at 180Wh/kg which is 25% lower than NMC and why they can now be used in cars as NMC/NMg are ~225Wh/kg + packaging problems and here LFP are actually a bit better allowing MUCH larger flat square cells instead of small round cells due to fire concerns. I believe TESLA is getting around fire concerns with their larger NMC cells by making a fully wet battery for cooling purposes. Extra weight, but cooling is becoming an ever bigger concern for longevity and helps solve the fire problem. 2 birdies, 1 stone. LFP does not need the fully wet battery, and does need to be warmed, so will probably try to get away with just air to bypass galvanic corrosion of stray electric currents from said heater. Of course how well it will cool said giant cells is somewhere below dubious which will ultimately limit performance for regenerative braking massively and acceleration of course, but also for any applications larger than very lightweight vehicles. Vast majority of EV's are LiNMg, not LiNMC. Same is true for cell phones. Cheaper as well. Yea yea, some cell phones go with NMC in their high end models. Any cheap cell phone? AKA, vast majority; no. Quote Share this post Link to post Share on other sites
