| titleOfInvention | Cathodic vacancy cathode material and preparation method thereof |
| abstract | A cationic vacancy cathode material and a preparation method thereof relate to a lithium ion battery. The chemical formula of the cationic vacancy cathode material is Li a [Li b Mn c Co d Ni e ]O f . Dissolving at least one of a manganese salt, a cobalt salt and a nickel salt in deionized water to prepare a mixed salt solution A; dissolving sodium carbonate and ammonium hydrogencarbonate in deionized water to prepare a solution B; mixing the salt solution A Adding solution B to obtain a mixed solution; the mixture is allowed to stand, filtered, washed, and dried to obtain a carbonate precursor; after the dried carbonate precursor is calcined, an oxide precursor is obtained; an oxide precursor is obtained The body is mixed with a lithium salt, and after sintering, a cationic vacancy positive electrode material is obtained. After the precursor product obtained by the coprecipitation method is uniformly mixed and sintered with an appropriate amount of the lithium source lower than the stoichiometric ratio, a layered positive electrode material having a large amount of cationic vacancies in the bulk phase is obtained. A positive electrode material containing a cationic vacancy can reduce the amount of lithium source used and reduce production costs. |
