Structural Battery Electrode With CNT Interlayer for Conductive Strength

An intermediate layer comprising carbon nanotubes and/or graphene is introduced between the matrix and the carbon fiber fabric. This intermediate layer serves as a mediator that maintains electrical conductivity pathways while allowing the matrix to provide mechanical support. The intermediate layer prevents direct electrical incompatibility between the matrix and carbon fiber, thus resolving the contradiction between mechanical strength enhancement and electrical conductivity maintenance.

The electrode is structured as a composite material system with multiple layers: carbon fiber fabric substrate, intermediate layer with carbon nanotubes/graphene, and matrix layer. This composite structure allows each layer to fulfill its specific function - the carbon fiber provides baseline conductivity, the intermediate layer enhances conductivity and bridges the electrical gap, and the matrix provides mechanical strength. The composite approach enables simultaneous achievement of mechanical strength and electrical conductivity.

The matrix is designed with a porous structure that allows continuous ion transport pathways. The porosity enables ions to move through the solid matrix without requiring a separate liquid electrolyte layer. This approach maintains reliable ion transport while simplifying the overall device structure by eliminating the need for distinct solid and liquid components.

The matrix is designed to serve multiple functions simultaneously: providing mechanical support, enabling ion transport through its porous structure, and maintaining structural integrity. By making the matrix multi-functional, the invention eliminates the need for separate components, thus reducing device complexity while maintaining reliable ion transport capability.
