Abstract:
A high-rate lithium cobaltate cathode material, which contains a multi-channel network formed by fast ionic conductor Li α M′ γ O β , mainly consists of lithium cobaltate. The lithium cobaltate is melted together with the fast ionic conductor Li α M′ γ O β  in the form of primary particles to form secondary particles. Besides, the lithium cobaltate is embedded in the multi-channel network formed by fast ionic conductor Li α M′ γ O β . The element M′ in Li α M′ γ O β  is one or more of Ti, Zr, Y, V, Nb, Mo, Sn, In, La, W and 1≤α≤4, 1≤γ≤5, 2≤β≤12. The lithium cobaltate cathode material is mainly obtained by uniformly mixing cobaltous oxide impregnated with a hydroxide of M′ and lithium source, then by the sintering reaction in an air atmosphere furnace at a high temperature. The product of the present invention can greatly promote the lithium ion conductivity of the lithium cobaltate cathode material during the charging and discharging process of the lithium-ion battery, and improve the rate performance of the material.

Claim (Index 1):
