Abstract
A compact modular electrical energy storage device comprising one or more cell modules in which certain components of the device are maintained in a substantially fixed position in the device by utilizing a resilient porous body of compressed carbon fibers to resiliently urge the components into physical contact with one another. The invention further provides means for maintaining the cell components in such fixed position during cell operation at elevated temperatures for extended periods of time. A preferred compact cell module construction particularly suitable for use in a high-temperature, high-energy-density lithium battery includes two positive electrode assemblies positioned in opposing relationship by a U-shaped spacer member maintained in contact with a separator member of each positive electrode assembly by a resilient porous body of compressed graphite fibers, a unitary double-faced negative electrode assembly being positioned between the two positive electrode assemblies.
