A battery pack has bus bars at one end, freeing the other end of the battery pack for cooling or other arrangements. A plurality of battery cells oriented in the same manner in the battery pack has first terminals of the battery cells at first ends of the battery cells. Portions of second terminals of the battery cells are at the first ends of the battery cells. The first ends of the battery cells are in a coplanar arrangement. A plurality of bus bars is assembled proximate to the first ends of the battery cells. The bus bars are coupled to the first terminals and the second terminals of the battery cells at the first ends of the battery cells to place the battery cells in a series connection and a parallel connection.

In accordance with an example embodiment of the present invention, an apparatus is disclosed. The apparatus includes a single battery ribbon and vacuum packaging. The single battery ribbon includes a first portion, a second portion, and an interconnecting portion between the first portion and the second portion. The first portion includes a first block. The second portion includes a second block. The first portion, the second portion, and the interconnecting portion form a continuous single layer including an anode and a cathode. The vacuum packaging surrounds the single battery ribbon. The vacuum packaging includes a middle connecting portion configured to contact a first side of the interconnecting portion and a second opposite side of the interconnecting portion.

The present application relates to a battery. According to the invention, the battery comprises a housing made of plastic, which has a cavity delimited by an inner wall of the housing, in which a stack of electrodes is arranged and an electrolyte solution is filled. At least one feed-through element protrudes from a surface of the housing through the housing at least partially into the cavity. At least one contact element made of a conductive material is arranged inside the cavity and is conductively connected to the at least one feed-through element. The at least one contact element is arranged in the cavity in such a way that tab elements of like-poled electrodes of the electrode stack are held in a clamping manner between at least a first surface of the at least one contact element and the inner wall.

A miniature electrochemical cell has a total volume that is less than 0.5 cc. The anode is a lithium sheet that is swaged onto an inner surface of a casing tube to form an anode lumen. The cathode comprises CF.sub.x contacting a rod-shaped current collector and the cathode having a cylindrical shape resides in the anode lumen. The rod-shaped cathode current collector has a cylindrically-shaped outer surface extending along a longitudinal axis. At least one helical groove recessed into the outer surface turns around the longitudinal axis at a constant distance while moving parallel to the axis. The helical groove prevents the CF.sub.x from sliding on or delaminating from the rod-shaped current collector. A separator segregates the anode from contacting the cathode, and an electrolyte activates the anode/cathode.
