Researchers built a lithium-ion battery made of graphene and silicon, which was claimed to last over a week on one charge and took only 15 minutes to charge. [134] In 2015 argon-ion based plasma processing was used to bombard graphene samples with argon ions. That knocked out some carbon atoms and increased the capacitance of the materials ...
In addition, it is known that when single-layer graphene is supported on an amorphous material, the thermal conductivity is reduced to about 500 – 600 W⋅m −1 ⋅K −1 at room temperature as a result of scattering of graphene lattice waves by the substrate, [172] [173] and can be even lower for few-layer graphene encased in amorphous ...
In current lithium-ion battery technology, the 2D networks of graphite inhibit smooth lithium-ion intercalation; the lithium ions must travel around the 2D graphite sheets to reach the electrolyte. This slows the charging rates of the battery. Porous graphene materials are currently being studied to improve this problem.

The resulting "pom-poms" (what you see above) aren't at all tasty, but their open 3D structure makes them far better for transferring electrical charges than plain graphene. Deep-fried graphene ...
Energizer Holdings, Inc. is an American manufacturer and one of the world's largest manufacturers of batteries, headquartered in Clayton, Missouri. [2] [3] [4] It produces batteries under the Energizer, Ray-O-Vac, Varta, and Eveready brand names and formerly owned several personal care businesses until it separated that side of the business into a new company called Edgewell Personal Care in 2015.
