A cell structure that can improve heat dissipation and the vibration-proofing nature of a cell without using a cooling medium while keeping the rigidity and the discharge current quantity of the cell includes at least one electrode having a positive pole active material layer, a current collector and a negative pole active material layer. The cell structure also includes a separator provided between each electrode; and a casing. The cell structure satisfies the inequality: S c × 1000 > b × 1000 S wherein b (mm) indicates a short-side length of the electrode, S (m2) indicates an electrode area, c (mm) indicates a cell structure thickness and 1000 (m2/mm) is a constant. The separators have a different Shore A hardness and the separator having the lowest Shore A hardness is placed at a center of the cell structure.

The disclosure relates to bipolar cells including electrodes surrounding a collector. Embodiments of the bipolar cells include a collector containing a highpolymer material. The disclosure also relates to bipolar electrode batteries containing bipolar cells including a collector body containing electrically conductive highpolymer or electrically conductive particles distributed in a high-polymer. By adding such high molecular weight polymer material to the collector, the weight of the collector may be reduced and the output power density per weight of the battery may be improved. The disclosure further relates to methods of forming collecting bodies and electrodes for bipolar cells using an inkjet printing method. Bipolar cells according to the present invention may be used to fabricate batteries such as lithium ion batteries, which may be connected to form battery modules used, for example, to provide electrical power for a motor vehicle.
