EXAMPLE - An organic solvent (100 g) containing ethylene carbonate (30 vol.%), propylene carbonate (10 vol.%), and ethylmethyl carbonate (10 vol.%) was added with 2-(methacryloyloxy) ethyl acetoacetate (0.25 g). The resulting organic solvent and Li phosphorus hexafluoride-containing compound (LiPF6) were added to prepare 1.0 M electrolytic solution. A two-electrode battery based on Li metal that had small specific surface area was manufactured and then the secondary electrode battery was run three times at scan rate of 1 mV/sec by cyclic voltammetry in 2.5-0 V as measured against a reference electrode. The electrolytic solution had 93.2% cycle efficiency and 350 mAh/g capacity for the first cycle.
