HIGH-ENTROPY SINGLE CRYSTAL CORE-SHELL STRUCTURED CATHODE ACTIVE MATERIAL FOR LMFP/LFP AND NCMA/NMx

A cathode electrode includes a cathode current collector and a cathode active material layer arranged on at least one side of the cathode current collector. The cathode active material layer includes cathode active material comprising a plurality of cores each including a single crystal particle and a high entropy layer encapsulating each of the single crystal particles of the plurality of cores. The high entropy layer includes at least 5 different transition metal elements.
