  • Patent number: 10714749
    Abstract: A high-rate lithium cobaltate cathode material, which contains a multi-channel network formed by fast ionic conductor Li?M??O?, mainly consists of lithium cobaltate. The lithium cobaltate is melted together with the fast ionic conductor Li?M??O? 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?M??O?. The element M? in Li?M??O? is one or more of Ti, Zr, Y, V, Nb, Mo, Sn, In, La, W and 1???4, 1???5, 2???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.

  • Patent number: 10706987
    Abstract: A LiBH4—C60 nanocomposite that displays fast lithium ionic conduction in the solid state is provided. The material is a homogenous nanocomposite that contains both LiBH4 and a hydrogenated fullerene species. In the presence of C60, the lithium ion mobility of LiBH4 is significantly enhanced in the as prepared state when compared to pure LiBH4. After the material is annealed the lithium ion mobility is further enhanced. Constant current cycling demonstrated that the material is stable in the presence of metallic lithium electrodes. The material can serve as a solid state electrolyte in a solid-state lithium ion battery.
