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 an internal space defined by at least one internal wall and a base. The mandrel comprises a longitudinal axis, and is positioned in the container such that the longitudinal axis passes through the internal space and the base. The sheet of separator material is arranged about the mandrel to provide a plurality of discrete separator layers which are spaced apart in a packing direction normal to the longitudinal axis. At least one electrode is provided between each of the discrete separator layers, and the mandrel has at least one hollow column running along the length of its longitudinal axis such that a part of the base is accessible via the hollow column.
