A housing for a button cell battery includes a top, a can and a grommet. The skirt of the can extends between a top panel and a free end, and includes a substantially vertical first section and an outwardly tapered second section. The first section extends from the top panel of the can. The second section extends from the first section. Upon assembly of the housing, a flow path is defined between an outer surface of the skirt of the grommet and the inner surface of the skirt of the can. The flow path allows air to escape during the assembly, thus minimizing the risk of gas being entrapped within the interior of the housing of the finished cell battery.

A battery cell, suitable for use in an electric vehicle, includes a prismatic conductive casing having an electrically conductive casing body with a width (W), a height (H) and a thickness (T) and having a generally rectangular cross-section when seen in the thickness direction (z). A stack of layer assemblies is accommodated in the casing body, each layer assembly including a cathode layer, an anode layer and a separator layer there between, the layers extending in a width direction (x) and in a height direction (y) and being of a generally rectangular shape, a stack height extending in the thickness direction (z). The cathode and anode layers each include a cathode tab and an anode tab, respectively, one set of tabs extending in the width direction (x) along a lower part, substantially along the width (W) of the casing and being in conductive contact with a bottom of the casing.

An exterior material to be used for a battery includes a barrier layer, a first functional layer formed on one surface of the barrier layer, a second functional layer formed on the other surface of the barrier layer, and an anti-corrosion layer formed on at least one surface of the barrier layer. The first functional layer is composed of one or more resin layers including a sealing layer, and the second functional layer has a greater thickness than the barrier layer and has a thickness of 33% or more of the total thickness of the exterior material.

A battery, and a method for manufacturing at least one battery. The method includes forming a stack formed by an alternating succession of cathode strata and anode strata, each cathode stratum forming cathode entities and each anode stratum forming anode entities. The method further includes conducting a heat treatment and/or a mechanical compression of the formed stack to form a consolidated stack, and then making a pair of main cuts between two adjacent empty zones, in a top view, so as to expose an anode connection zone and an cathode connection zone, and to separate a given battery, formed from a given row (R.sub.n), from at least one other adjacent battery, formed from at least one adjacent row (R.sub.n+1).
