<P>PROBLEM TO BE SOLVED: To provide a battery which is superior in adhesiveness of an electrode and a separator to an electrolyte, and which enables to improve cycle characteristics. <P>SOLUTION: A positive electrode 11 and a negative electrode 12 are laminated via the separator 23 and the electrolyte 24. The electrolyte 24 becomes a so-called gelatinous state in which an electrolytic solution is retained by a polymer compound. Peeling-off strength in a T-character test of the negative electrode 12 and the separator 23 is 70 N/m or more and 1,200 N/m or less. Within this range, while adhesiveness of the negative electrode 12 and the separator 23 to the electrolyte 24 is retained, destruction of the negative electrode 22 due to expansion and shrinkage accompanying charge and discharge can be suppressed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
