NOVELTY - The battery cell (1) has a cell housing (2) which comprises cell terminal (3). The cell terminal is provided with an electrode of the battery cell, and a region of the cell terminal with free end projecting from the cell housing. The region has a lower portion (5) extending from the cell housing, an upper portion (6) extending up to the free end, and an intermediate portion (7) which connects the lower portion with the upper portion. The intermediate portion is designed such that the upper section over the intermediate portion is arranged resiliently resetting at the lower portion.    USE - Battery cell e.g. lithium-ion cell for use with cell connector used in battery (all claimed) used as energy store for powering hybrid, plug-in hybrid and electric vehicles.    ADVANTAGE - The structural stability of an electrically conductive connected battery cells and cell connectors is increased to facilitate the interconnection of the battery cells to battery or battery module. The cell contacted with the connector section of the cellular terminals is designed to give a thermally induced expansion of the cell to follow the expansion of connector, without mechanical stresses in the connection between the cell terminal and the cell connectors. The welding of the second portion of the cell terminals with cell connector is enabled, without the battery cell being affected by welding heat. Since the kinking or bending of the cell terminals, during transport of the battery cells or when connecting to the cell terminals or on the battery work is performed, the elastic restoring bendability of the second portion of cell terminals is largely prevented. The material in relation to the dimensioning of the cell terminals is saved and thus weight reduction of the battery cell can be realized. The first portion and/or the second portion formed of metal strip or metal pin is relatively easy, simple and inexpensive to produce. The problem of the mechanical stresses in relation to the areas in which cell terminals are connected with the connecting elements of cell connector is compensated by the cell terminal. The insulating and conductive connections of the cell terminals can be made very flat and material saving.
