Abstract: Battery packs are presented having structural members for improving thermal management of battery cells therein. In some embodiments, the battery packs include a first end-member positioned opposite a second end-member and parallel thereto. The battery packs also include a first side beam positioned opposite a second side beam and parallel thereto. The first side beam and the second side beam extend longitudinally between the first end-member and the second end-member. A longitudinal member is disposed between the first side beam and the second side beam and defines a plurality of longitudinal rows. The battery packs may additionally include a lateral member disposed between first end-member and the second end-member to partition the plurality of longitudinal rows into an array of battery cell compartments. A battery cell is disposed within at least one battery cell compartment.

Abstract: Battery packs according to some embodiments of the present technology may include a first longitudinal beam and a second longitudinal beam. The battery packs may include a plurality of cell blocks disposed between the first longitudinal beam and the second longitudinal beam. The plurality of cell blocks may include first and second cell blocks each characterized by a first side surface proximate the first longitudinal beam, a second side surface, a third side surface proximate the second longitudinal beam, and a fourth side surface. The battery packs may include a first interface material thermally coupling the first side surface of the first cell block with the first longitudinal beam. The battery packs may also include a second interface material thermally coupling the third side surface of the second cell block with the second longitudinal beam.

Abstract: Battery packs are presented. The battery packs include a plurality of cell blocks, each cell block comprising a plurality of battery cells. The battery pack also includes a plenum chamber configured to fluidly couple each of the cell blocks to an exterior of the battery pack in response to a thermal event in the battery cell in a separate cell block. In some embodiments, at least one of the cell blocks is configured to be fluidly coupled to the plenum structure via a cell block vent.

Abstract: Insulators and polymer-coated insulators are provided. The insulators can include thermally-insulating nanoparticles and a binder configured to volatilize at a volatilization temperature. Insulators can also include an inorganic thermally-insulating material forming a porous structure. The porous structure can be configured to reduce the mean free path of gases in the insulator as compared to gases outside the porous structure. Polymer-coated insulators including an inorganic thermally-insulating material and a polymer coating disposed on the surface of the inorganic thermally-insulating material are also provided. Insulators can also include thermally-insulating nanoparticles and an opacifier. The opacifier can include a carbonaceous material coated with a refractory material that inhibits oxidation of the carbonaceous material at a carbon oxidation temperature. The insulators or polymer-coated insulators can be disposed between battery cells or battery cell blocks in an apparatus.
