CPC Code(s): H01M50/242
Abstract: excessive expansion of rechargeable batteries during recharging is a significant concern since the uncontrolled buildup of high internal battery pressures from expansion inside a confined space can lead to separator membrane failure and/or thermal runaway of a battery cell. a crushable foam or honeycomb insert layer is placed inside of a rigid battery fixture to automatically limit the progressive buildup of internal battery pressure due to charging-induced expansion of the battery cell during recharging. the crushable insert layer is included as part of the rigid battery fixture. aluminum honeycomb cores and porous aluminum metal foam materials have a significant amount of crushability over a very wide range of compressive strains. alternatively, a porous metal foam or metal honeycomb material may be infused with a liquid polymer (e.g., silicone, rubber, edpm, or polyurethane) to enhance the mechanical properties of the polymer-infused metal foam or honeycomb metal/polymer composite material.
