Номер: CN103199242A
Автор: Xu Shoujiang, Chen Yujuan
Принадлежит:

The invention belongs to the technical field of lithium ion battery, and especially relates to a borosilicate coated and modified lithium cobaltate which comprises a core layer and a shell layer, wherein the core layer is the lithium cobaltate and has a particle size of 1-30 [mu]m, and the shell layer is the borosilicate with a structural formula: ROx-SiO2-B2O3, 0< x <= 3, and has a thickness of 5-150 nm. Compared with prior art, according to the method, the borosilicate is coated on surfaces of the lithium cobaltate powder, and because the borosilicate has performances of low moisture residue, relatively low thermal expansion coefficient, low heat conduction performance, high chemical stability and good dielectric properties, the borosilicate, after being coated on the surface of the lithium cobaltate, can play an isolation and protection role and improve safety performance of electrical core. Furthermore, due to a protective film formed on the surface of the lithium cobaltate by the borosilicate ...
