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.

Abstract: This disclosure provides an electrode having a carbon-based structure with a plurality of localized reaction sites. An open porous scaffold is defined by the carbon-based structure and can confine an active material in the localized reaction sites. A plurality of engineered failure points is formed throughout the carbon-based structure and can expand in a presence of volumetric expansion associated with polysulfide shuttle. The open porous scaffold can inhibit a formation of interconnecting solid networks of the active material between the localized reaction sites. The plurality of engineered failure points can relax or collapse during an initial activation of the electrode. The open porous scaffold can define a hierarchical porous compliant cellular architecture formed of a plurality of interconnected graphene platelets fused together at substantially orthogonal angles. The hierarchical porous compliant cellular architecture can be expansion-tolerant and can expand in a presence of Li ion insertion or de-insertion.
