▎ 摘　　要

NOVELTY - Battery cathode comprises base layer and porous carbon add-on. The porous carbon addendum is disposed on the base layer. The porous carbon add-on includes a multiple of pore-like structures for embedding positive ions from the positive electrode of the battery. The base layer includes a deposition structure for embedding positive ions from the positive electrode of the battery. The embedding mating area of the hole-shaped structure is larger than that of the deposition structure. USE - Battery cathode. ADVANTAGE - The Battery cathode has improve the lithium ion and sodium ion plasma de-embedding efficiency of a battery cathode, thus avoiding ion deposition to form dendritic crystal, and improves charging efficiency and use safety of the battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a battery, which comprises battery positive electrode, electrolyte, and battery cathode electrode; and (2) method for processing the cathode electrode of a battery, which involves preparing porous carbon add-on material, and disposing the porous carbon add-on material on the base layer of the negative electrode of the battery to obtain cathode electrode of a battery.
