Heat build-up is a major design consideration in large battery modules such as those used in data centers. Excessive battery temperature can reduce the reliability of equipment in a data center and can pose safety problems. This disclosure describes techniques that encase the cells of the battery module in a potting medium, which can be a semi-rigid or liquid material of moderate-to-high thermal conductivity and low electrical conductivity. The encasing results in improved cooling, energy density, and safety.
