1. A cathode comprising:
a catholyte material including at least one of: a solid electrolyte material, a blended radical polymer poly(4-glycidyloxy-2,2,6,6-tetramethylpiperidine-1-oxyl) with poly(poly(ethylene oxide) methyl ether methacrylate), and a blended poly(3,4-ethylenedioxythiophene) polystyrene sulfonate with polyethylene oxide; and
a plurality of cathode active material particles each comprising a core and a cathode active material disposed on a surface of the core,
the core being formed of at least one selected from the group consisting of: a carbon material, a polymer that includes an aromatic cycle, and a polymer having at least one double bond, and
the cathode active material including at least one selected from the group consisting of: a lithium transition metal oxide, a lithium olivine-type material, and a sulfur material.
