Abstract
A cell module has a plurality of electrochemical pouch cells. Each pouch cell has at least a first and second electrode, a separator arranged between the electrodes, and a flexible outer sleeve. Each pouch cell has a circular outer rim and a circular through-hole arranged in the center of the pouch cell. An outer cell terminal is arranged on the outer rim of each pouch cell, and an inner cell terminal is arranged on an inner rim of the through-hole. The cell module has an inner current collector in the form of a cylindrical rod and an outer current collector in the form of a cylinder jacket. The inner current collector extends along a mid-axis of the cell module, and the outer current collector is arranged concentrically with respect to the inner current collector.
