US, China scientists achieve 100% voltage recovery in aging batteries, could 2x lifespan

A breakthrough in battery technology could double the lifespan of lithium-ion batteries. Scientists from China and the U.S. have achieved 100% voltage recovery in aging batteries using materials with zero thermal expansion properties. By developing a zero thermal expansion cathode and applying 4V pulses, researchers reconstructed the battery's lattice structure. This innovation prevents thermal expansion, enhances structural integrity, and could potentially double battery lifespans in electric vehicles through smarter recharging systems.
