  • Publication number: 20240154109
    Abstract: The present invention provides a multi-element, regionally doped, cobalt-free positive electrode material, which has a molecular formula of LixNiaMnbAlcMgdWeO2, wherein 0.95?x?1.1, 0.5?a?0.9, 0.1?b?0.5, 0?c?0.01, 0?d?0.01, 0?e?0.01, and a+b=1. The positive electrode material comprises an Al-doped region, an Mg-doped region and a W-doped region in an order from the inside to the outside. Also provided is a method of preparing the positive electrode material. The cobalt-free positive electrode material of the present invention can better adapt to a stress release by the positive electrode material regionally doped with Al, Mg, and W elements, achieving a moderate adjustment and avoiding imbalance, so that the material has more stable structure, and better rate performance and cycle performance. The method of preparing the material has a simple process, is easy to implement, and can stably prepare a positive electrode material with excellent structure and performance.
