Solid Energy touts lithium metal electrodes to safely boost lithium ion battery energy density by up to 40% and could lower costs by half to about $130 per kilowatt hour
A new MIT spinoff company, SolidEnergy says it has materials that can increase the amount of energy that lithium-ion batteries store by 30 percent or more and lower costs enough to make electric vehicles affordable. SolidEnergy replaces the graphite electrode used in conventional lithium-ion batteries with a high-energy lithium-metal one. That’s been tried before, but …
