摘要：

The effect of Li2CO3-coating on the performance of natural graphite in a Li-ion battery was studied. It is shown that Li2CO3-coating can effectively increase reversibility of the initial forming cycle of Li/graphite half-cell. More interestingly, the Li2CO3-coating significantly suppresses self-delithiation of the lithiated graphite, which enhances storage performance of the Li-ion battery. The Li2CO3-coated graphite also shows higher capacity retention after long-term cycling. (C) 2003 Elsevier B.V. All rights reserved.
