Title: (EN) METHOD FOR PRODUCING COATED NICKEL-BASED LITHIUM-NICKEL COMPOSITE OXIDE PARTICLES
(ZH) 带包覆膜的镍系锂-镍复合氧化物颗粒的制造方法
Abstract: front page image
(EN) The invention provides: coated nickel-based lithium-nickel composite oxide particles which are able to be handled in the atmosphere and enable the achievement of a coating film of a lithium ion conductor having no adverse effects on battery characteristics; and a method for producing the coated nickel-based lithium-nickel composite oxide particles. A method for producing coated nickel-based lithium-nickel composite oxide particles, which comprises: an organic compound radicalization step wherein a radicalized organic compound is obtained by introducing an organic compound having 8 or less carbon atoms into a reaction gas, which has been excited into a plasma in the atmosphere, together with a carrier gas and radicalizing the organic compound; and a coating step wherein the surface of eachnickel-based lithium-nickel composite oxide particle is covered with a coating film that contains an organic compound of a polymer or copolymer by bringing the radicalized organic compound into contact with the surfaces of the nickel-based lithium-nickel composite oxide particles.
(ZH) 本发明提供一种带包覆膜的镍系锂‑镍复合氧化物颗粒及其制造方法,能够在大气环境下进行处理且能够得到对电池特性无不利影响的锂离子传导体的包覆膜。本发明的带包覆膜的镍系锂‑镍复合氧化物颗粒的制造方法,包括:有机化合物自由基化工序,将碳原子数为8以下的有机化合物与载气一同导入在大气压下经等离子体化的反应中,将该有机化合物自由基化,从而获得自由基化有机化合物;以及包覆工序,通过使自由基化有机化合物与镍系锂‑镍复合氧化物颗粒的表面接触,从而在该镍系锂‑镍复合氧化物颗粒的表面包覆含有作为聚合物或共聚物的有机化合物的包覆膜。
