BATTERY

Zusammenfassung

[0001] In an initial state, a battery (10) is in the following state. A laminate (100) has a thickness T<0> from a first electrode (110b) to a first electrode (110c). A first position (P1) is spaced from the end portion of a separator (130a) on the first position (P1) side by a distance L<0> in a direction perpendicular to a thickness direction of the laminate (100) . The end portion of a first tab (112a) on the first position (P1) side protrudes toward the first position (P1) from the end portion of the second electrode (120a) on the first position (P1) side, by a distance G in the direction perpendicular to the thickness direction of the laminate (100) . The laminate (100) is designed such that, even if the laminate (100) swells in the thickness direction of the laminate (100), the thickness of the laminate (100) from the first electrode (110b) to the first electrode (110c) is smaller than 4×{(T<0>/2)<2>+L<0>2 -(L<0>-G)<2>}<1/2>.
