Project Overview:

Cross-plane thermal transport generally limits heat removal from the multilayer stacks that form prismatic and spiral-wound batteries. The heat must conduct to the case through many layers of the anode-separator-cathode structure. Few measurements of thermal conductivity exist, even for common cathode and anode materials, and the in situ interface resistance is virtually unknown. We are currently measuring the cross-plane thermal conductivity and interface resistances within battery cells using a miniaturized version of the conventional reference bar method integrated with high-resolution infrared thermography to quantify thermal properties in realistic battery geometries and conditions.
