Publication number: 20250015287Abstract: A compositely coated ternary precursor, and a preparation method therefor and use thereof are provided. The material includes a ternary precursor and a coating layer attached to a surface of the ternary precursor, wherein the coating layer is obtained from a precipitation reaction of a first metal ion and a first polyanion. The metal ion and the polyanion can undergo a precipitation reaction to form a precipitate, to form a uniformly distributed coating layer on the surface of the ternary precursor. After the coated precursor is sintered into a cathode material, part of the coating can form a protective layer on the surface of the material; and the other part of the coating can permeate into the material to form bulk phase doping.Type: ApplicationFiled: August 12, 2022Publication date: January 9, 2025Inventors: Yongguang Li, Changdong Li, Genghao Liu, Weiquan Li, Dingshan Ruan, Yong Cai

Publication number: 20230391635Abstract: The present invention discloses a radially-structured nickel-based precursor and a preparation method thereof. An overall shape of the precursor is a secondary sphere formed by agglomeration of primary crystal grains; and the secondary sphere has a loose and porous network core inside and uniform and regular strip primary crystal grains outside, and the strip primary crystal grains grow outward perpendicularly to a surface of the core and are arranged radially and closely. The precursor structure of the present invention is more suitable for high-power battery cathode materials. The internal loose structure is more likely to form a void in the center during a preparation process of a cathode material, which helps to expand a contact area between an active material and an electrolyte.Type: ApplicationFiled: August 18, 2023Publication date: December 7, 2023Inventors: Weiquan Li, Changdong Li, Dingshan Ruan, Yong Cai, Genghao Liu, Hongjia Lin
