Abstract: Method for repairing plastic dividers (1), having longitudinal internal cavities (100), by following the steps of: identifying and extracting the damaged areas to be repaired (2), some gaps (4) being defined, preparing inserts (5) with a shape matching the gaps (4), and attaching by heat welds (8) the inserts (5) in the gaps (4); wherein the damaged areas to be repaired are extracted by cuts (3) with a curved path, and wherein in the step of preparing the inserts (5), the inserts are machined with an outer edge (50) aligned with the edges (10) of the divider (1), and an inner edge (51) parallel to the curved path of the cut (3), there being defined between the cut (3) made in the divider (1) and the inner edge (51) of the insert (5) a filling space (7) for filling with filler material (8).

Abstract: Provided is a battery assembly that includes an electrically-conductive housing (510A, 510B), one or more battery modules (512) electrically coupled to a busbar (522), the one or more battery modules and busbar being received in the housing. A non-woven core layer (506) is disposed between the busbar and electrically-conductive housing, the non-woven core layer comprising a plurality of fibers, the plurality of fibers comprising 60-100 wt % of oxidized polyacrylonitrile fibers. The non-woven core layer can exhibit a breakdown voltage of at least 0.9 kV at ambient conditions after exposure to 500° C. for 5 minutes.

Abstract: A ceramifiable composition comprises a crosslinked silicone matrix retaining stabilizing components. The stabilizing components comprise subcomponents: a) at least one of an aluminosilicate clay, aluminum oxide, or a hydrate thereof; b) at least one of phosphorus pentoxide, a polyphosphate, an inorganic phosphate salt, boron oxide, boric acid or a salt thereof; and c) at least one of an alkaline earth oxide, alkaline earth carbonate, or a hydrate thereof, and wherein heating the ceramifiable composition to a temperature between 600 and 1600 degrees Celsius, inclusive, results in a ceramified composition. An article including a layer of the ceramifiable composition and a method of making the same are also disclosed.

Abstract: A battery assembly comprises an assembly housing, a plurality of battery modules disposed within the assembly housing and electrically coupled to a busbar, and at least one ceramifiable pad disposed within the assembly housing. Each battery module comprises a plurality of individual cells disposed within a module housing. The at least one ceramifiable pad is disposed between at least one of: at least two of the individual cells, at least two of the battery modules, the busbar and the assembly housing, or at least one of the battery modules and the assembly housing. The ceramifiable pad comprises a ceramifiable composition. Heating the ceramifiable composition to a temperature between 600 and 1600° C., inclusive, results in a ceramified composition. Ceramifiable compositions and methods of making them are also disclosed.
