<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery etc., with high reliability and with excellent input/output characteristics across a wide temperature range. <P>SOLUTION: A lithium secondary battery 100 is provided with a positive electrode plate 121 and a negative electrode plate 131. When its own SOC is set at any arbitrary figure within 20% to 90%, a low temperature resistance ratio (R1a/R2a) of a positive electrode resistance R1a of the positive electrode plate 121 to a negative electrode resistance R2a of the negative electrode plate 131 at -10°C is to be 3/7 to 3/2, and a normal temperature resistance ratio (R1b/R2b) of a positive electrode resistance R1b of the positive electrode plate 121 to a negative electrode resistance R2b of the negative electrode plate 131 at 25°C is to be 2/3 to 7/3. <P>COPYRIGHT: (C)2011,JPO&INPIT |
