A Simple Way to Make Lithium-ion Battery Electrodes that Protect Themselves

Menlo Park, Calif. — Scientists at three Department of Energy national laboratories 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.

Study Finds a Way to Prevent Fires in Next-Generation Lithium Batteries

Researchers discovered that adding two chemicals to the electrolyte of a lithium metal battery prevents the formation of dendrites – “fingers” of lithium that pierce the barrier between the battery’s halves, causing it to short out, overheat and sometimes burst into flame.
