A simple way to make lithium-ion battery electrodes that protect themselves

Scientists have discovered how to keep a promising new type of lithium ion battery cathode from developing a crusty coating that degrades its performance. The solution: Use a simple manufacturing technique to form the cathode material into tiny, layered particles that store a lot of energy while protecting themselves from damage.

Technique matters: Different way to make cathodes may mean better batteries

Lithium nickel manganese cobalt oxide, or NMC, is one of the most promising chemistries for better lithium batteries, especially for electric vehicle applications, but scientists have been struggling to get higher capacity out of them. Now researchers have found that using a different method to make the material can offer substantial improvements.
