Application of thermally conductive silicone pads in battery modules

The thermal performance of battery modules impacts critical factors such as battery safety, performance, and lifespan. Both excessively high and low temperatures can affect the battery pack, necessitating temperature control to ensure stable operation over extended periods.

Common battery modules consist of multiple batteries. During discharge, these modules generate significant heat. Heatsinks are typically installed on the top and bottom of the battery pack to guide heat from one side of the battery to the other, where it is then dissipated by air or liquid cooling. However, gaps exist between the battery pack and the heatsink, containing air that hinders heat transfer efficiency, thus reducing the effectiveness of heat dissipation.

Therefore, thermally conductive silicone pads are used to fill the space between the heatsink and the battery pack, eliminating air at the interface and improving heat transfer efficiency. Thermally conductive silicone pads are a commonly used traditional thermal conductive material. They possess high thermal conductivity, low thermal resistance, insulation, and resistance to thermal shock. Placed between the heat source and the heat sink, they fill the gaps at the interface and eliminate air, reducing contact thermal resistance and improving thermal conductivity. Furthermore, the soft and elastic texture of thermally conductive silicone pads provides some shock absorption, making them highly suitable for the power battery pack industry.

Temperature-conducting silicone pads are made from ordinary silicone and undergo a series of special processes to transform them into silicone thermally conductive pads with excellent thermal conductivity. Their primary function is to transfer heat in high-temperature products.
