    摘要： A cap assembly for a battery includes a roll combination member, a terminal combination member, an electrode terminal, a strength reinforcing block, a cap, and a pad assembly. The roll combination member includes at least one opening, so that terminal disposed portions of 2k rolls are capable of passing through the opening and k is an integer greater than 1, wherein one terminal disposed portion is formed by bending portions of central members of two adjacent rolls. The terminal combination member, the electrode terminal, the strength reinforcing block, the cap, and the pad assembly are sequentially combined on the roll combination member, wherein the electrode terminal includes an electrically conductive portion and a thermally conductive portion which surrounds the electrically conductive portion. The cap assembly is electrically connected to the bending portions at the same side of the 2k rolls.
