摘要：

Mesoporous carbon (MC) was utilized to increase the mesoporosity of LiCoO2 composite cathode. Graphite powder (GP) was chosen as a standard of comparison because of its very low mesoporosity. Compared with MC, GP has similar particle size, lower specific surface area, and higher electronic conductivity. Acetylene black (AB) exists in the form of chains of nanoparticles. With all other factors held constant, the mixture of AB and MC (ABMC)-loaded LiCoO2 composite cathode (ABMC cathode) was superior to the mixture of AB and GP (ABGP)-loaded LiCoO2 composite cathode (ABGP cathode). The reason is ...
