| titleOfInvention | Ultra-high nickel and low cobalt single crystal cathode material and preparation method thereof |
| abstract | The invention discloses an ultra-high nickel and low cobalt single crystal positive electrode material and a preparation method thereof. The ultra-high nickel and low cobalt single crystal positive electrode material comprises an ultra-high nickel and cobalt-free single crystal inner core and a cobalt-rich shell layer, which are passed through a composite lithium salt solid phase. The method of cascade calcination realizes that the cobalt-rich shell layer is uniformly coated on the surface of the ultra-high nickel and low cobalt single crystal core. The composite lithium salt is used as the molten salt, which has a lower melting temperature than the single lithium salt, so that it can be used at a relatively low temperature. The nucleation and rapid growth of single crystal particles can be realized at high temperature, avoiding the use of excessively high calcination temperature and a large amount of flux, and solving the serious problem of Li + /Ni 2+ cation mixing in ultra-high nickel and low cobalt single crystal materials; The long-cycle stability of ultra-high nickel and low cobalt single crystal cathode materials, the preparation process is simple, and it is fully compatible with existing production line equipment, which can effectively achieve cost-reducing iterations of high-nickel single crystal products in the market. |
