NOVELTY - The holder (2a) has recesses and/or projections cooperating with recesses and/or projections of an adjacent holder, where the holder is made of plastic. A set of frame walls (6a) is arranged on entire boundary edges of both sides of a base wall (5a) and protrudes from the base wall, where the base wall and the frame walls enclose sides of a rechargeable battery cell (3). The base wall or the frame walls is/are adapted for a point and/or narrow type contact with the cell, where the base wall and the frame walls are integrated as a one-piece component.    USE - Stackable holder for use in a modular system for holding a rechargeable prismatic battery cell i.e. lithium ion battery cell (claimed), in battery-driven electric cars. Can also be used for high-performance electric and electronic devices, and niche applications such as forklift and mining cars.    ADVANTAGE - The base wall or the frame walls is/are adapted for a point and/or narrow type contact with the cell, so that an extension compensation is realized, the cooling channels are freely configurable, and the contact pressure is selectively adjustable for each cell. The design of the holder enables direct contact of the heat transfer medium with the cell, thus ensuring effective heat transfer. The holder can be used for any type of batteries. The design of the holder enables forming of a stable housing for the battery cells, even when used with flexible battery cells. The holder is formed as a one-piece component, so that the holder can be recycled in a simple manner, the battery can be manufactured with fewer components in a quick manner both by manual and machine operations and can be dismantled in an easy manner, and the danger of incorrect assembly of the battery is avoided.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a battery.    DESCRIPTION OF DRAWING(S) - The drawing shows a longitudinal sectional view of a battery.
