Ultra-high nickel single crystal cathode material and preparation method thereof |
| abstract |
The invention discloses an ultra-high nickel single crystal positive electrode material and a preparation method thereof. LiNi x Co y M 1-x-y O 2 is synthesized by using a solid-phase method step calcination combined with a step lithium supplement technology; The platform has a shorter calcination time, which can realize the nucleation and rapid growth of single crystal particles under a relatively short high temperature calcination platform, forming a framework of ultra-high nickel single crystal materials, while avoiding the occurrence of lithium evaporation caused by excessive high temperature calcination time The phenomenon of depletion of lithium can solve the problems of serious Li + /Ni 2+ cation mixing, increase of lattice oxygen defects and volatilization of lattice lithium in ultra-high nickel single crystal cathode materials. Suppress the mixing of Li + /Ni 2+ cations caused by high temperature synthesis, effectively reduce the residual alkali on the surface, and improve the discharge capacity and cycle stability of the material; this process is fully compatible with existing production line equipment, and can effectively achieve ultra-high nickel single crystal products cost reduction iteration. |
