Graphene supercapacitors are moving from lab curiosity to serious contender for the next wave of electric vehicle energy storage. By pairing the near-instant charging of capacitors with the high ...

Voltage fade has quietly limited some of the most promising lithium-ion cathodes, eroding the energy they can deliver long ...

Trace tungsten dopants stabilize lithium-rich battery cathodes, sharply reducing voltage fade over hundreds of cycles.

Lithium-rich layered oxides (LRLOs) offer exceptionally high capacities but suffer rapid energy loss because of irreversible migration of ...

Japanese vehicle maker Toyota, for the first time, is producing electric vehicle batteries in North America in what used to be agricultural land of North Carolina.
