Abstract
This disclosure provides a lithium (Li) ion battery that includes an anode, a cathode positioned opposite to the anode, a porous separator positioned between the anode and the cathode, and a liquid electrolyte in contact with the anode and the cathode. The anode includes an electrically conductive substrate. A first film is deposited on the electrically conductive substrate. The first film includes a first concentration of carbon particles in contact with each other and defines a first electrical conductivity for the first film. Each of the carbon particles includes a plurality of aggregates formed of few layer graphene sheets. The plurality of aggregates form a porous structure configured to undergo a lithiation, which can include any one or more of an intercalation operation or a plating operation. The anode and the cathode can include an electroactive material. The porous structure can provide conduction between the few layer graphene sheets.
