Abstract
In this paper we report the thermal conductivity for commercial battery components. Materials were obtained from several electrode- and separator manufacturers, and some were extracted from commercial batteries. We measured with and without electrolyte solvent and at different compaction pressures. The experimentally obtained values are used in a thermal model and corresponding internal temperature profiles are shown. The thermal conductivity of dry separator materials was found to range from 0.07±0.01 to 0.18±0.02WK−1m−1. Dry electrode (active) materials ranged from 0.13±0.02 to 0.61±0.02WK−1m−1. Adding the electrolyte solvent increased the thermal conductivity of electrode (active) materials by at least a factor of 2.
