Polyaniline synthesized by chemical polymerization is replace acetylene black to be used as the conductive additive of LiCoO2 cathode. FTIR shows that polyaniline prepared possesses the typical features of conductive emeraldine salts. The conductivity of polyaniline is 15.29 S cm-1 which is more than that of acetylene black. Polyaniline has some discharge capacity in the potential range of cathode, so it can be used as the cathode material. The conductivity changes of LiCoO2 cathode film with the increase of the content of conductive additive c...
