The application provides a high-nickel ternary material modification method and a high-nickel positive electrode material with a nitrogen-oxygen coating layer, and relates to the field of lithium ion batteries. In the high-nickel ternary material, surface lattice oxygen is gradually replaced by nitrogen atoms in a high-temperature long-time calcination process in a nitrogen-oxygen mixed atmosphere, so that a nitrogen-oxygen layer is formed on the surface, which is beneficial to the delocalization of electrons, thereby endowing the material with excellent electronic conductivity; meanwhile, the presence of the nitrogen-oxygen layer inhibits the transformation of the surface layer structure into a rock salt phase structure, which is beneficial to realizing efficient ion transport. The formation of the nitrogen-oxygen layer on the surface of the high-nickel ternary material can simultaneously improve the electronic and ionic conduction of the surface of the high-nickel positive electrode material, inhibit the interface side reaction, relieve the volume change, and thereby improve the cycle stability of the battery.

This invention relates to a method for preparing superconducting targets using reaction sintering. The invention provides three reaction sintering processes for preparing superconducting targets, which can rapidly advance densification at ambient pressure and lower peak temperatures, avoiding the problems of excessive precipitation of Ba / Cu-rich liquid phase and insufficient densification caused by high temperature or high pressure. This achieves the preparation of high-density superconducting targets without Ba / Cu liquid phase precipitation and volatilization, and less prone to cracking, thereby improving the critical current density and other properties of the superconducting targets. Specifically, the low-temperature synthesis-pulverization process can prepare targets with higher density and better critical current density and other properties; the low-temperature synthesis-jaw crushing process can prepare high-density targets with a higher yield, better supporting mass production; and the low-temperature negative pressure synthesis-pressureless sintering process balances high density and yield, while eliminating high-pressure tooling, simplifying the sintering process, and reducing equipment wear.
