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.

Conformal graphene cage encapsulated battery electrode materials and methods of forming thereof

A battery electrode material includes: 1) primary particles formed of an electrochemically active material; and 2) a secondary particle defining multiple, discrete internal volumes, wherein the primary particles are disposed within respective ones of the internal volumes.

Large-volume-change lithium battery electrodes

Described here is a method for making an anode of a rechargeable battery, comprising incorporating a composition comprising LiM into the anode, wherein M is a Group 14 element. Also described here is an anode comprising a composition comprising LiM, wherein M is a Group 14 element, and a rechargeable battery comprising the anode.
