Abstract:

This disclosure provides an electrochemical cell electrode including a film layer deposited on an electrically conductive substrate. The film layer includes a concentration of carbon aggregates formed from a plurality of few layer graphene sheets orthogonally fused together. A porous structure is defined by the plurality of few layer graphene sheets and is configured to any provide for electrical conduction between contact points between any two or more of the plurality of few layer graphene sheets or host an electroactive material. The electrochemical cell electrode can be an anode. The electroactive material can include an elemental lithium (Li) interspersed in a D-spacing between adjacent few layer graphene sheets in the anode. An additional film can be deposited on the film. The film can be configured to provide a first electrical conductivity and the additional film can be configured to provide a second electrical conductivity different from the first electrical conductivity.
