摘要：
A battery cathode including a current collector and a cathode material coated on and/or filled in the current collector, said cathode material including a cathode active substance, a conductive additive and an adhesive, wherein said cathode material is coated with a layer of lithium cobaltate on the surface thereof and the content of lithium cobaltate is 0.1-15 wt % (weight percent) based on the weight of the cathode active substance. The lithium ion battery using the cathode provided by the present invention has a higher specific capacity and improved cycling performance.
