Lithium EV batteries retain 93% capacity after 500 cycles with US heating method

Stanford and SLAC researchers developed a revised cathode heating process for lithium-ion batteries.

The method reduces internal cracking in nickel-rich layered-oxide cathodes, helping cells retain about 93% capacity after 500 cycles.

It does not require extra materials or added manufacturing complexity.

The approach could improve battery economics for EVs, data centers, and grid-scale energy storage.
