BATTERY CELL AND CELL GROUP IN A BATTERY

摘要

The invention relates to battery cells (2) of a battery, in particular of a lithium-ion battery, said cells (2) having a longitudinal axis and a thermally conductive jacket (7) that extends in the longitudinal direction and encases the cell (2). The invention also relates to a cell block or cell group (1) consisting of battery cells (2) of this type, said block or group being placed in the battery housing of a battery, in particular a vehicle battery, especially a battery for a vehicle with a hybrid drive or a fuel-cell vehicle, in particular a high-voltage battery. The aim of the invention is to provide battery cells (2) and a corresponding cell group (1), which is cost-effective to produce and is compact for installation in a battery housing. To achieve this, the jacket (7) of the cells (2) is a sleeve, the wall thickness of which varies around its circumference.
