摘要： The battery is sealed by a sealing member including a safety valve for exhausting the gas generated in the battery to the outside of the battery when the pressure in the battery is increased. A part of the sealing member is formed of a member having a melting point lower than that of high-temperature gas generated in the abnormal time and having a ratio of an area of an opening of the battery case to an area of a gas exhaust hole is 3.0×10−5 or more and 9.1×10−3 or less.

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.
