Patent ID: 10454147

Abstract:
Battery packs for high energy density batteries (cells), particularly arrays of such batteries are described herein. The battery packs include a microfibrous media (MFM)-phase change materials (PCM) composite block and one or more active cooling structures. The MFM is typically sintered to the active cooling structures. The battery packs may contain more than one MFM-PCM composite block. Additionally or alternatively, the MFM-PCM composite block may contain different layers containing different MFM-PCM composites, which have different functionalities. In a preferred embodiment, at least one layer contains a flame retardant PCM, while at least one other layer contains a PCM with a lower melting temperature. The cells may be arranged in a repeating square or equilateral triangle pattern, with one or more active cooling structures in the geometric center of the square or triangle.
