Nickel-cobalt-manganese ternary cathode materials were favored by the market due to the advantages of high energy density and excellent cycling performance.However,the disadvantages of high residual alkali on the surface and poor safety performance have caused consumers to linger.Inorganic solid electrolyte has the characteristics of high ionic conductivity and high structural stability,so it will be very attractive in all solid-state batteries in the future.In the next few years,lithium-ion secondary batteries with traditional structures will also occupy most of the battery market share.The solution of compounding the ternary cathode material with the inorganic solid electrolyte material is a nice option.Some cases of compounding ternary cathode materials with five types of inorganic solid electrolytes were briefly introduced such as typical NASICON type,garnet type,LISICON type,β-eucryptite type,and sulfide type.And the current research was reviewed.Challenges and trends in the future application process as well were talked.
