A framed lithium battery cell group includes a first frame member () and a second frame member (). The frame members are locked together, clamping the lithium battery cell pack () on the seal edge surfaces (), thereby providing structural rigidity and protection from damage due to handling and vibration. Each of the frame members () has multiple pins () and sockets () on the side opposite the clamping surface () to facilitate aligning and stacking multiple lithium battery cell pack and frame assemblies to form a lithium battery cell group (). Each of the frame members () include a buss bar capture feature () having a bus bar () inserted therein for electrically connecting all of the terminals for a given lithium battery pack group to the buss bar ().

Apparatus and method for securing battery cell packs

A method of constructing a battery using a control unit to cause battery components to be drawn through an automated conveyor system and between indexed positions on the conveyor system is provided. Positive terminals for a battery are attached to a first carrier strip having indexing apertures. Negative terminals for a battery are attached to a second carrier strip having indexing apertures. Spools, controlled by control unit, are engaged in the indexing apertures of the first and second carrier strips and rotated for movement of carrier strips and terminals through indexed construction positions.

Battery constructed with indexing conveyor system and continuous terminal chain

A method of constructing a battery using a control unit to cause pallets on an automated conveyor system to move between indexed positions on the conveyor system. Control unit causes terminals to be deposited on said pallet in a first position, control unit causes pallet to be moved to a second position, and a delivery mechanism controlled by control unit deposits bicells on said terminals with use of an alignment plate, said alignment plate on a separate circulating conveyor, controlled by control unit. Bicells are aligned to be in electrical contact with said terminals.

Battery constructed with extracted bicells stacked on shuttled pallet

A battery pack containing a plurality of battery modules, these modules comprising a plurality of individual battery units, these battery units comprising a plurality of bicells with opposing terminals. The battery modules are connected in series by use of a flexible circuit and by opposing positive and negative terminals of each battery unit. The terminals of each battery unit contain a region of apertures which allow the adhesive of the packaging material to seal more effectively, thereby eliminating or reducing the amount of leakage from an individual battery unit.

Battery pack having flexible circuit connector

A battery pack containing a plurality of battery modules, these modules comprising a plurality of individual battery units, these battery units comprising a plurality of bicells with opposing terminals. The battery modules are connected in series by use of a flexible circuit and by opposing positive and negative terminals of each battery unit. The terminals of each battery unit contain a region of apertures which allow the adhesive of the envelope-like packaging material to seal more effectively by flowing through the apertures and sealing to itself, thereby eliminating or reducing the amount of leakage from an individual battery unit. The terminals pass through overlapped edges of the packaging material and include tangs for electrical connection to flaps formed in the flexible circuit.
