  • Publication number: 20240283080
    Abstract: A battery pack includes a housing, a battery cell assembly, a first separator, a pressure relief portion, and glue. The first separator is disposed between the housing and a first side of the battery cell assembly, and is deformed when a temperature is higher than a first threshold. The glue fills a clearance between the housing and at least a partial area outside the first side of the battery cell assembly and is configured to fasten the battery cell assembly to the housing. When thermal runaway occurs in the battery pack, the first separator is thermally deformed to form a first pressure relief channel between the housing and the first side of the battery cell assembly. Then, high-temperature gas can smoothly escape from the battery pack through the first pressure relief channel and the pressure relief portion.

  • Publication number: 20220372309
    Abstract: The present invention provides a coalescing agent for aqueous coatings, a coalescing agent composition, and an aqueous coating. The coalescing agent for aqueous coatings is obtained by esterification reaction of fatty acids and glycol ethers. The coalescing agent prepared by the present invention has a boiling point as high as 330° C., has no irritant odor, and is environmental friendly and safe. It overcomes shortcomings of conventional coalescing agents, which is suitable for various polymer emulsion systems, and can significantly reduce the film-forming temperature of aqueous emulsion coatings and optimize the film-forming performance.
