Abstract
A conformal graphene-encapsulated battery electrode material is formed by: (1) coating a battery electrode material with a metal catalyst to form a metal catalyst-coated battery electrode material; (2) growing graphene on the metal catalyst-coated battery electrode material to form a graphene cage encapsulating the metal catalyst-coated battery electrode material; and (3) at least partially removing the metal catalyst to form a void inside the graphene cage.

A method of forming a conformal graphene-encapsulated material, comprising:
- coating a battery electrode material with a metal catalyst to form a metal catalyst-coated battery electrode material;
- growing graphene on the metal catalyst-coated battery electrode material to form a graphene cage encapsulating the metal catalyst-coated battery electrode material;
- and
- at least partially removing the metal catalyst to form a void inside the graphene cage.
A conformal graphene-encapsulated material comprising:
- a graphene cage defining an internal volume;
- and
- a battery electrode material disposed within the internal volume,
- wherein the battery electrode material occupies less than 100% of the internal volume to define a void.
