The battery cassette may further include a seal component having one or more hollow tubes aligned with the hollow tubes of the frame. The frame and the seal component may be configured to receive one or more battery cells in the hollow tubes.

Batteries are provided that include a base including a body having a hole, and an inner wall extending away from the base and disposed around the hole. An interior of the inner wall and the hole form at least part of a through-hole extending through the battery. The battery includes an outer wall extending away from the base and disposed around the inner wall. Cells are disposed on the base and between the inner wall and the outer wall. Structural battery packs are also provided that include: a hollow elongated member including a first interior space between its first and second ends; and one or more batteries disposed around the hollow elongated member between its first and second ends. Each battery includes a through-hole. The hollow elongated member is disposed through the through-hole of each battery. Methods related to the batteries and the structural battery packs are also provided.

A battery housing has a body and a lid mateable with the body. The body and the lid, when mated, provide a chamber dimensioned to hold at least one battery; and a venting passageway from the chamber. At least a portion of at least one of the body and the lid comprises an intumescent flame retardant material with an expansion ratio sufficient to drive gas from the chamber through the venting passageway and to seal the chamber when the material intumesces in the event of thermal runaway of a battery housed in the chamber.

An example of a thermal composite includes a substrate, a primer layer, a first adhesive layer, a blanket layer, a second adhesive layer, and a metal layer. The blanket layer includes basalt fibers or glass fibers. The thermal composite may be incorporated into a battery pack as a battery enclosure.

A battery pack to be used in motorized furniture is provided. The battery pack includes a plurality of polymer cells. The plurality of polymer cells is connected such that a threshold voltage is achieved. The battery pack also includes a motherboard coupled to the plurality of polymer cells. The motherboard is configured to monitor and regulate each cell in the plurality of cells, as well as the entire plurality of cells as a whole. The motherboard is further configured to regulate power flow throughout the plurality of cells such that more than two motors may operate at the same time.

A battery pack includes a plurality of battery modules that includes a plurality of battery cells, a battery cell holder, a second-electrode assembly including a plurality of second-electrode bus bar plates, a first-electrode assembly, and a cover. The first-electrode assembly includes a plurality of first-electrode bus bar plates, a first-electrode terminal, a second-electrode terminal connected to one of the plurality of second-electrode bus bar plates, and an inter-electrode bus bar connecting the second-electrode bus bar plate and one of the first-electrode bus bar plate and the first-electrode terminal. The first-electrode assembly is in a first pattern or a second pattern. An arrangement of the first-electrode terminal and the second-electrode terminal in the battery module differs according to the pattern of the first-electrode assembly.

A battery module, which includes at least one battery cell and a module case for packaging the at least one battery cell, wherein the module case includes: a top cover configured to cover an upper side of the at least one battery cell; and a side plate configured to cover all of opposing side surfaces of the top cover and opposing side surfaces of the at least one battery cell and configured to be coupled to the top cover by fitting.
