PURPOSE: A case of a reusable battery is provided to improve the safety degree of the reusable battery by adopting a plurality of PTFE(polytetrafluorethylene) layers. CONSTITUTION: A case of a reusable battery(20) contains an electrode assembly(24) consisting of an anode(21), a separator(23), and a cathode(22) which are sequentially accommodated in the case(29) of the reusable battery(20). The case(29) of the reusable battery(20) comprises a plurality of polytetrafluorethylene layers(210,220) which are formed at an innermost layer with respect to the electrode assembly(24). A nylon layer(240) is formed at an outermost layer with respect to the electrode assembly(24). An aluminum foil layer(230) is formed between the polytetrafluorethylene layers(210,220) and the nylon layer(240). |
