Higher Li-Ion Battery Efficiency

This week in batteries: "Scientists from the U.S. Department of Energy’s Ames Laboratory discovered a first-of-its-kind copper and graphite combination that, they say, could have implications for improving the energy efficiency of lithium-ion batteries. “Copper is a highly conductive material but susceptible to oxidation. Being able to successfully embed it just underneath the surface of graphite protects the copper, and suggests a number of potential applications, including battery technology,” Research Assistant Ann Lii-Rosales said in a press release."

I've no idea what this means but they seem to be really excited about it.
