    • The subject invention discloses apparatus and methods to provide compression of an electrochemical cell independent of atmospheric pressure. One aspect of this invention is directed towards a lithium ion cell assembly which is surrounded by a layer of material under tension, so that the material applies pressure which compresses the cell to enhance contact between the anode, separator, and cathode layers. Specifically, a heat shrink material (material which reduces in size, or contracts in at least one dimension of a three-dimensional conformation, due to the application of heat) is provided about a laminar battery and shrunk in situ to provide a battery package. Another embodiment of this invention is directed towards a lithium ion cell asembly in which a sealed package contains both the battery and a spring element. The spring element within the package applies pressure to the battery to compress it and improve contact between the anode, separator, and cathode layers.
    • 本发明公开了提供独立于大气压力的电化学电池压缩的装置和方法。 本发明的一个方面涉及一种锂离子电池组件,该锂离子电池组件被张力下的一层材料包围,使得该材料施加压力以压缩电池以增强阳极,隔板和阴极层之间的接触。 具体而言,提供了一种热收缩材料(尺寸减小的材料,或由于施加热而在三维构象的至少一个维度中收缩的材料),并围绕层状电池进行原位收缩以提供电池组。 本发明的另一实施例涉及锂离子电池组件,其中密封包装包含电池和弹簧元件。 封装内的弹簧元件对电池施加压力以将其压缩并改善阳极,隔板和阴极层之间的接触。
