NOVELTY - The battery (1) has a set of individual cells (3) electrically connected with each other in parallel or series and arranged in a battery case (5). An air guidance element (8) is arranged in or at the battery case and is designed as a sealingly locked hollow body, where the individual cells are thermally connected with outer side of the air guidance element in a form-fit, positive and/or force fit manner. A set of bars (8.1) is vertically arranged in the air guidance element such that a set of air guide channels (K) is formed in the air guidance element.    USE - Battery i.e. lithium ion high volt battery, for use as an automotive battery for a vehicle e.g. hybrid vehicle and gas cell vehicle.    ADVANTAGE - The battery case is formed adjacent to a screen of the cells in a sealed configuration, thus reducing the risk of penetration of emergent gases into a vehicle interior through opening of the cells. The bars are vertically arranged in the air guidance element such that air guide channels are formed in the air guidance element, thus enabling improved heat transportation by increased heat transfer and improving cooling of the battery in a profitable manner. The individual cells are thermally connected with the outer side of the air guidance element in the form-fit, positive and/or force fit manner, so that the cells in the battery case are hermetic and are shielded absolutely and sealingly from the cooling air led into the air guidance element, thus avoiding contamination and corrosion of the cells, and hence lowering the danger of leaks and short-circuits. The cells are arranged in the battery case and are electrically and parallely or serially connected with each other such that effective cooling of the individual cells is enabled, and the battery can be manufactured in a simple and economic manner.
