Samsung’s Reveals Li-Ion Battery with Graphene Balls: Higher Capacity, Faster Charging

Samsung on Tuesday announced that it had developed a way to improve Lithium-Ion batteries with its new material called graphene balls. The company says that batteries featuring the new material charge five times faster than conventional Lithium-ion accumulators and enable a considerably higher volumetric energy density.

The new battery technology developed by Samsung SDI and its partners* uses the so-called graphene balls (a 3D structure synthesized from silicon dioxide, Si02) to cover a cathode and also as an anode material. Graphene balls on the catho…
