Abstract
An energy storage device comprising: a container, a mandrel, at least one sheet of separator material, and two or more electrodes. The container comprises a base and an inner surface forming an internal space. The mandrel is positioned in the container and is spaced apart from the inner surface to define a cavity within the container. The sheet of separator material is arranged about the mandrel to provide a plurality of discrete separator layers within the cavity. At least one electrode is provided between each of the discrete separator layers, and at least a portion of an external surface of a container has a curved profile.
