Positive electrode plate to which carbon-coated phosphoric acid-based ceramic particles are added

Abstract

The application discloses a positive plate added with phosphoric acid ceramic particles coated with carbon layers; a general solid-state battery structure comprises a positive electrode, a negative electrode and a dielectric film layer attached between the positive electrode and the negative electrode; wherein the positive electrode comprises the positive plate, which comprises: a positive electrode substrate; a positive electrode slurry layer coated on the positive electrode substrate, the positive electrode slurry layer being composed of positive electrode slurry, the positive electrode slurry comprising: a plurality of positive electrode particles; an adhesive; a dispersing agent; a plurality of conductive additives; a plurality of composite ceramic particles for guiding lithium ions and dispersing the channels of lithium ions; each of the composite ceramic particles comprises a ceramic particle, and a carbon layer coated on the outer surface of the ceramic particle; the carbon layer is used for preventing the surface of the ceramic particle from reacting with oxygen ions and solvents in the positive electrode slurry, and the carbon layer itself has good conductivity.
