摘要
Abstract
A certain amount of nano-mesoporous carbon spheres (NCSs,8％) mixed with lithium iron phosphate (LiFePO4) and graphite as active material was assembled into the Li-ion battery.After adding NCSs,the reversibility and specific capacity of the battery were better than those without NCSs,especially,when charged-discharged at 9.0 A,the charge voltage platform was showed lower about 0.25 V,the charge-discharge efficiency was increased about 88％.The ratio of output capacity and the capacity at the current of 0.8 A was higher about 15％.At low temperature of 0 ℃,-10 ℃ and-20 ℃,the ratio of the output capacity of battery adding NCSs to the rated capacity was 12.4％,14.9％ and 16.7％ higher than that of the non-adding one,respectively.关键词
