Abstract: A battery has a wrapper member comprising the combination of an inner layer which is pervious to gases generated by the cell and an outer layer which is impervious to liquids and which is less pervious than the inner layer to the gases generated by the cell. The inner and outer layers are laminated to one another throughout some but not all of their coextensive surfaces, with the unlaminated portions providing a passageway between the two layers for the venting of gases generated on the interior of the battery; the passageway communicates with the exterior of the battery. Preferably the inner and outer layers have coextensive surfaces which cover the entire area enclosed by the peripheral seal of the battery, and the inner layer extends into the area of and forms a component of the peripheral seal; in that case the gas passageway may extend to the area above the seal. Preferably the inner layer is an electrically conductive plastic and the outer layer is a metal.

Abstract translation: 电池具有包装部件，该包装部件包括可透过电池产生的气体的内层和不透液体的外层的组合，并且内层与由电池产生的气体相比不太透明。 内层和外层在其一部分但不是全部共同表面上彼此层压，其中未层压部分在两层之间提供通道，用于排出在电池内部产生的气体; 该通道与电池的外部连通。 优选地，内层和外层具有覆盖由电池的周边密封件包围的整个区域的共同延伸的表面，并且内层延伸到周边密封件的区域并形成周边密封件的部件; 在这种情况下，气体通道可以延伸到密封件上方的区域。 优选地，内层是导电塑料，而外层是金属。
