Cradle-to-Crisis Approach Improves Battery Safety & Performance

Battery failures can escalate quickly: Heat accumulates, materials break down, and gases ignite in a chain reaction known as thermal runaway. Such events are rare thanks to carefully applied safeguards in material design and battery management systems. Still, continued research is needed to anticipate how new battery materials behave, understand … [continued]
