Description

LiCoPO4-carbon composites (LiCoPO4/C) were synthesized via a solid state reaction with a new furnace black, CB1, which was developed by Asahi Carbon Co., Ltd. The CB1 used here has superiority physico-chemical properties, e.g., ultrafine particle sizes, high specific surface areas, and high “structure”, the degree of linkage among carbon particles. The particle growth of LiCoPO4 was suppressed by the addition of CB1 to the LiCoPO4 precursors and then followed by calcination. CB1 was dispersed among LiCoPO4/C particles successfully to form conductive paths. Consequently, a high electrochemical capacity was achieved in aid of the presence of CB1.
