<P>PROBLEM TO BE SOLVED: To provide a battery capable of improving high temperature characteristics. <P>SOLUTION: An anode contains an anode activator containing Si as a constituent element. A separator is impregnated with electrolyte liquid containing solvent and electrolyte salt. Normal temperature melting salt composed of cation expressed by general formula (1), and anion like N<SP>-</SP>(CF<SB>3</SB>SO<SB>2</SB>)<SB>2</SB>is contained in the solvent. In general formula (1), R1 denotes 1 to 4C alkylene group, R2 denotes alkyl group, allyl group, aryl group, heterocyclic group, aralkyl group, or alkoxyalkyl group. <P>COPYRIGHT: (C)2007,JPO&INPIT |
