Abstract
An electrochemical cell includes a housing, and an electrode assembly disposed in the housing. The electrode assembly comprises a positive electrode, a negative electrode and a separator disposed between the positive electrode and the negative electrode. The housing is formed of a first case half and a second case half. Each case half is formed of a metal foil laminate material and includes a wedge-shaped central recess that is surrounded by a flange. The flange of the first case half is joined to the flange of the second case half along a seal line that surrounds the respective central recesses. The central recesses cooperate to define an interior space of the housing that contains the electrode assembly, and the interior space has the shape of a rectangular prism. The seal line extends along a diagonal of a side of the rectangular prism. A method of forming the housing is described.
