    摘要: A battery module supports a stack of nested electrochemical cells. Each cell includes an electrically-conductive container including a bottom, and a sidewall surrounding a periphery of the bottom. Each cell includes an electrically-conductive cell cover configured to close an open end of the container, an insulating gasket disposed between the container and the cell cover and an electrically-conductive jelly roll electrode set disposed in the container. The cell cover is formed having a recess configured to receive the bottom of an adjacent cell. In particular, the recess is configured to conform to the shape and size of the bottom of the adjacent cell so that when the cells are stacked end-to-end, a cell stack is formed in which the cells of the stack a) fit within each other in a nested arrangement, and b) form an electrical connection.

    摘要: Disclosed are a cap assembly for a secondary battery and a secondary battery including the cap assembly. The cap assembly includes: a safety vent made of a circular metal plate and consisting of a central portion corresponding to the central area of the metal plate and a peripheral surrounding the central portion, the central portion including a current-carrying contact forming a first conductive path through which an electric current generated from a power generating device flows to the outside and a breakable junction forming a second conductive path at the center of the central portion; a cap-down opposite to the safety vent, having a central hole through which the breakable junction is exposed, and including a support member in close contact with the peripheral portion; and a sub-plate joined to the breakable junction and having a notch formed around the breakable junction, the outer circumferential surface of the sub-plate and the cap-down interposing an insulating layer therebetween. The cap assembly can be used to increase the capacity of the power generating device in the secondary battery compared to when used in other secondary batteries of the same size, minimizes the contact resistance between terminals, is constructed at reduced cost, and can protect a gasket disposed between a battery can and the safety vent from being melted or lost by energy or force generated upon external electrical shorting to prevent electrical shorting of the secondary battery.
