<P>PROBLEM TO BE SOLVED: To provide a secondary battery excellent in output characteristics, by using a polymer electrolyte having high ion conductivity. <P>SOLUTION: The lithium secondary battery comprises an anode and cathode for occluding/discharging lithium reversibly, and an electrolyte. The electrolyte contains a boron contained compound expressed in formula 1 and electrolyte salt. In formula 1, B represents boron atom, Z<SB>1</SB>, Z<SB>2</SB>, Z<SB>3</SB>represent an organic part containing an acryloyl group or a methacryloyl group, or a hydrocarbon radical of a carbon number 1-10 where one or two of Z<SB>1</SB>, Z<SB>2</SB>, Z<SB>3</SB>are an organic part having the acryloyl group or methacryloyl group, AO represents an oxyalkylene group of carbon number 1-6, and is formed by one or more than one, and l, m, n represent an average addition mole number of an oxyalkylene group, and is greater than 0 and less than 4, where 1+m+n is 1 or more. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
