Abstract
An electrode composite material is disclosed in the invention. The electrode composite material comprises ABxCyDz, wherein A is selected from at least one of polypyrrole, polyacrylonitrile, and polyacrylonitrile copolymer; B comprises sulfur; C is selected from carbon material; D is selected from metal oxides, l≦x≦20, 0≦y<l, and 0≦z<1. Comparing to the prior art, the conductivity of the electrode composite material is obviously increased, the material is dispersed uniformly and the size of the material is small. The electrochemical performance of the electrode composite material is improved. It has a good cycle life and high discharging capacity efficiency. A method for manufacturing the electrode composite material, a positive electrode using the electrode composite material and a battery including the same are also disclosed in the invention.
