PURPOSE:To improve charge-discharge coulomb efficiency and life performance of a lithium negative electrode by adding a molybdenum oxide to a solution, in which lithium salt is dissolved in an organic solvent, as an additive. CONSTITUTION:An electrolyte for a lithium storage battery is used, while lithium salt is dissolved into an organic solvent and thereto a molybdenum oxide is added. For this molybdenum oxide, molybdenum trioxide (MoO3), lithium molybdate (Li2MoO4), molybdenum dichloride dioxide (MoO2Cl2) or molybdenum tetrachloride monoxide (MoOCl4) are used, and concentration of adding molybdenum oxide is to be 0.001-0.5mol/l. In this way, charge-discharge coulomb efficiency and life performance of a lithium negative electrode can be improved. |
