SEPARATOR ASSEMBLIES FOR USE IN ENERGY STORAGE DEVICES, AND METHODS THEREOF

A separator assembly for use in energy storages devices comprising a separator layer and a supporting tape, and methods thereof are disclosed. Separator assemblies utilizing a supporting tape such as a barrier layer and/or a coil core layer provides additional support to prevent electrode buckling and to protect the separator layer from wear-related electrode buckling and puncture over the life of the energy storage device.
