Abstract: This disclosure provides a battery including a cathode, an anode positioned opposite the cathode and a carbon interface layer. The carbon interface layer includes an electrically insulating flaky carbon layer conformally encapsulating the anode. A plurality of carbon nano-onions (CNOs) defining a plurality of interstitial pore volumes are interspersed throughout the electrically insulating flaky carbon layer. An electrolyte is in contact with the carbon interface layer and the cathode. A separator is positioned between the anode and the cathode. The electrically insulating flaky carbon layer can include graphene oxide (GO). The plurality of interstitial pore volumes can be configured to transport lithium (Li) ions between the anode and the cathode via the plurality of interstitial pore volumes in a bulk phase of the electrolyte. The carbon interface layer can be configured to inhibit growth of Li dendritic structures from the anode towards the cathode.

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.
