Abstract: Embodiments described herein relate to electrochemical cell assemblies with structural members for application of compressive force. In some aspects, an electrochemical cell assembly can include a plurality of electrochemical cells arranged in a stack, a first planar sheet in contact with a first side of the stack, a second planar sheet in contact with a second side of the stack, a first structural member in compressive contact with the first planar sheet, and a second structural member in compressive contact with the second planar sheet, wherein the compressive contact between the first structural member and the first planar sheet and the compressive contact between the second structural member and the second planar sheet collectively provide structural rigidity to the electrochemical cell assembly.

Abstract: Embodiments described herein relate to heat transfer plates with dimples for removal of heat from electrochemical cell systems. In some aspects, an electrochemical cell system can include a first electrochemical cell, a second electrochemical cell, a first planar sheet contacting the first electrochemical cell, the first planar sheet including a first plurality of dimples, and a second planar sheet contacting the second electrochemical cell, the second planar sheet extending parallel to the first planar sheet, the second planar sheet separated from the first planar sheet by a separation distance, the second planar sheet including a second plurality of dimples, wherein the first plurality of dimples and the second plurality of dimples are both configured to induce turbulence in an air stream flowing parallel to the first planar sheet and the second planar sheet.

Abstract: A multi-cell battery system is provided including one or more independent, self-contained, modular battery sub-assemblies. A desired number of sub-assemblies may be assembled together in a desired arrangement to produce a custom battery system. Adjacent battery sub-assemblies may cooperate to receive a heat exchange medium for thermal management of the battery system.

A movement restraint is positioned behind the barrier and a dampener is positioned intermediate the barrier and the restraint.

Abstract: A structure is disclosed to protect explosive ordnance. The structure comprises an inner ceramic layer. A polyurethane layer encompassing the inner ceramic layer. A third layer is a stainless steel layer encompassing the polyurethane layer with a second polyurethane layer wrapping around the stainless steel layer. A fifth layer is an outer ceramic layer. A sixth layer through tenth layer comprises interconnected aramid fiber fabric (i.e., KEVLAR) impregnated with polyurethane. The structure may be part of an explosive handling system to include a shipping container that decelerates projectiles approaching the explosive device. The container comprises fifteen additional layers to encompass the structure. The first layer is steel encompassing the structure with a second layer through fifteenth layer of the container each being KEVLAR impregnated with polyurethane. Both the composite structure and the shipping container can be made from commercially available products.
