Abstract: Electrochemical behavior of LiB compound in LiPF6-DMC/EMC/EC was studied. And morphology of the compound was investigated by SEM. The results show that there are three discharge potential plateaus for the LiB compound, corresponding to 0.46, 0.69 and 0.8 V (vs Li+/Li) respectively, its total discharge specific capacity is up to 660 mA•h/g, only first two potential plateau can be charged, its specific capacity is 274 mA•h/g. After discharging, the morphology of the Li compound is still fibrous shape.
