A core (160, 210, 220, 230, 240) for insertion into an electrode assembly (110) of a rechargeable battery, for instance, comprises a spring member (161, 211, 221, 231, 241), and a pressing member (162, 212, 222, 232, 243) pressing the spring member member (161, 211, 221, 231, 241) into a compressed state and being formed at least partly of a material which dissolves in an electrolyte solution. |
