Energy storage cell

An energy storage cell, comprising:

• a cell body extending two-dimensionally in an extension plane and having four lateral planes arranged along a circumference of the extension plane, with two of said lateral planes extending in each case parallel to one another and with the extension plane having a center point;
• first and second conductor electrodes disposed symmetrically on one of said lateral planes with respect to a center of said one lateral plane in a circumferential direction of the extension plane, each said conductor electrode having an edge facing toward said center and an edge averted from said center;
• said electrodes forming a facing contact point where the edge of said conductor electrode facing toward said center contacts said one lateral plane, and said electrodes forming an averted contact point where the edge of said conductor electrode averted from said center contacts said one lateral plane;
• and
• wherein one or both of the following is true:
• said facing contact point including with said center of said one lateral plane an angle λ about said center point of the extension plane of 10°<λ<36°;
• said averted contact point including with said center of said one lateral plane an angle β about said center point of the extension plane of 8°<β<45°.

An energy storage cell, comprising:

• a cell body extending two-dimensionally in an extension plane and having four lateral planes arranged along a circumference of the extension plane, with two of said lateral planes extending in each case parallel to one another and with the extension plane having a center point;
• first and second rectangular conductor electrodes respectively disposed on two mutually opposite lateral planes, said conductor electrodes being disposed in each case symmetrically in the direction of the circumference about a center of the corresponding said lateral plane, and each said conductor electrode forming a contact point where an edge thereof contacts the respective said lateral plane, and said conductor electrodes having edges remote from the corresponding said lateral plane and extending non-parallel with the circumference of the extension plane;
• said contact points of one or both said conductor electrodes including with the center of the corresponding said lateral plane an angle λ about a center point of the extension plane of 20°<λ<60°;
• and/or said edges of said conductor electrodes remote from the corresponding said lateral plane including with the center of the corresponding said lateral planes for one or both conductor electrodes an angle γ about the center point of the extension plane of 25°<γ<55°;
• an angle β between a connecting line of edges formed between said lateral planes, which edges define said lateral planes that comprise said conductor electrodes in the direction of the circumference, and the center point of the extension plane on the one hand and a connecting line between the center of the respective said lateral plane and the center point of the extension plane on the other hand has a value of 40°<β<60°.
