Temperature gradient control with thermal interface material variation

This invention describes a system for cooling battery cells using a special adhesive. The adhesive contains tiny beads of a specific size, which act as spacers to maintain a precise gap between the battery cells and a cooling surface. This controlled distance helps manage how heat transfers from the batteries, aiming for a more even temperature distribution across the battery module.

Why it matters: The continuous push for higher energy density in battery packs makes precise thermal management more critical for safety and longevity. Advances in manufacturing and material science for thermal interface materials could make this precise spacing and thermal control more achievable and effective now.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateAdhesive with embedded beads, precise application
