  "textContent": "A particle structure of cathode material and a preparation method thereof is provided. Firstly, a precursor for forming a core is provided. The precursor includes at least nickel, cobalt and manganese. Secondly, a metal salt and a lithium ion compound are provided. The metal salt includes at least potassium, aluminum and sulfur. After that, the metal salt, the lithium ion compound and the precursor are mixed, and a mixture is formed. Finally, the mixture is subjected to a heat treatment step, and a cathode material particle structure is formed to include the core, a first coating layer coated on the core and a second coating layer coated on the first coating layer. The core includes potassium, aluminum and a Li-M-O based material. The first coating layer includes potassium and aluminum, and a potassium content of the first coating layer is higher than a potassium content of the core. The second coating layer includes sulfur.",
