Abstract
[PROBLEM] In space-conservative fashion, at low cost, and with high efficiency, to carry out absorption of gas produced at the interior of a battery. [SOLUTION MEANS] Secondary batteryis provided with casein which positive electrodeand negative electrodeare sealed together with electrolyte, and with explosion prevention valvefor allowing escape of high-pressure gas present at the interior of casewhen pressure within caserises; and is further provided with gas absorberorfor absorbing high-pressure gas. Gas absorber, includes gas-absorbent materialand capsule, which comprises hot-melt material, and is provided within case, this capsuleincluding, at the interior thereof, gas-absorbent material. Furthermore, gas absorber, which may be provided outside case, may include gas-absorbent material; cartridge casewhich houses, at the interior thereof, gas-absorbent material; gas inlet valvefor causing high-pressure gas to flow thereinto; and gas outlet valvefor causing high-pressure gas to flow out therefrom.
