The restraint members are coupled by grappling structures to the pair of end plates on two end portions along the lamination direction the battery cells, and the pair of end plates clamps the battery cell group in a state that the battery cell group is compressed and pulling forces toward opposite directions act on the two end portions of the restraint members by a restoration force when the battery cell group restores from the compression state.

A power supply device includes: a battery stack body that includes a plurality of secondary battery cells that are stacked; a pair of end plates disposed on both end surfaces of the battery stack body, respectively; and binding bars that are disposed on both the end surfaces of the battery stack body, respectively, and bind the pair of end plates. Each of the binding bars includes engaging steps that are opposite the pair of end plates, respectively. Each of the engaging steps extends in a direction intersecting with a stack direction of the battery stack body. Each of the pair of end plates includes engaging protrusions that are opposite the binding bars, respectively. The engaging protrusions engage with engaging steps. Consequently, rigidity that binds the battery stack body together is increased without changing a material and a thickness of the binding bars.

A battery plate having a substrate with opposing surfaces and one or more nonplanar structures and one or more active materials disposed on at least one of the opposing surfaces; wherein the battery plate includes one or more of: i) one or more projections disposed within but do not extend beyond the active material; ii) one or more projections which project beyond the active material and substantially free of the active material or dust formed from the active material; and/or iii) a frame about the periphery of the substrate which projects beyond the active material and is substantially free of the active material or dust formed from the active material; and wherein the battery plate is adapted to form part of one or more electrochemical cells in a battery assembly.

A frame can be mounted easily in an arrangement and which protects the cells received in the arrangement in as optimum manner as possible with high operational suitability, a frame for fixing cells, has a frame body, in which at least one cooling duct for a cooling medium is configured, wherein the frame has at least one plug-in piece for connecting to another frame, wherein the cooling duct runs at least partially within the plug-in piece.

A battery module of the present invention is adaptable to be utilized in various configurations including and not limited to an overlapping battery cell packaging configuration and a vertical stack battery cell packaging configuration used in an automotive and non-automotive applications. The battery module has a plurality of battery heatsink assemblies with the cells disposed therebetween. A plurality of rods extend through the each heatsink assemblies to secure the heatsink assemblies and the cell with one another to form the battery module.

An apparatus for mounting a battery cell mounts a battery cell stack to a frame that includes a base cover and a pair of side covers respectively extending from both ends of the base cover. The apparatus includes a support member to support the battery cell stack, a roller member around which a film fixed to the support member is wound, and a film guide member configured to move the film into the frame. When the film guide member moves the film into the frame, the support member and the frame move toward each other, and the battery cell stack is movable along the film to be mounted to the frame.

Provided are a method of manufacturing an all-solid battery and an all-solid battery manufactured by the method. The all-solid batter may have edge portions that can be more effectively insulated. In particular, the all-solid battery may include a cathode layer, an anode layer, and an electrolyte layer, a first insulator disposed at an edge of the cathode layer and a second insulator disposed between the cathode layer and the first insulator, thereby forming a membrane of the second insulator for preventing contact between the cathode layer and the anode layer in pressing.

A modular power storage and supply system having a plurality of stacked frame members retaining a plurality of pouch cells, each of the frame members having a pair of pressure contact members abutting the cell tab terminals of the pouch cells, the pressure contact members and cell tab terminals being approximately equal in contact surface area, the frame members being separated by a gap, the system having a compression mechanism that applies pressure to the combination of pressure contact members and cell tab terminals.

A battery pack includes a grouping of battery cells and a plurality of array frames for retaining the grouping of battery cells. Each of the plurality of array frames includes a ratchet feature.
