A Dash of Salts for EVs From Leyden Energy: Batteries are really just tiny canteens filled with a volatile che...

Batteries are really just tiny canteens filled with a volatile chemical soup. Leyden Energy claims it can improve performance, reduce costs and boost safety by changing some of the basic ingredients. The Fremont, California-based company produces lithium-ion batteries with an electrolyte based around a family of salts called IMIDE. Most other batteries use PF6-based electrolytes. While you probably don't know the difference between these chemical families, the difference to a lithium-ion battery is huge, claims CEO Aakar Patel. The electrolyte -- a liquid that carries charges between the anode and cathode in a battery -- in standard batteries degrades the cathode over time. The chemical reactions caused by the electrolyte also cause gases to be emitted. These gases, which are contained inside of the battery canister, can cause as much as 80 pounds of pressure to build insi...
