General Motors Innovates Cooling Solutions for Prismatic Battery Cells
General Motors (GM) is taking a significant step forward in electric vehicle technology with a novel approach to prismatic battery cell design aimed at enhancing cooling efficiency. A recent patent filing, initially submitted in June 2023 and published by the United States Patent and Trademark Office (USPTO) on December 26, 2024, outlines a unique configuration where battery layers are arranged in an inverted “U” shape.
This innovative design is expected to enhance thermal conductivity both horizontally and vertically, particularly in the upper and lower regions of the battery cell. Such advancements may lead to improved heat dissipation, ensuring that cooling systems remain effective when integrated into battery packs. GM suggests that this design can maintain lower peak temperatures, even in situations where the cells may experience overheating, thus enhancing safety and performance.
Moreover, the inverted “U” configuration could allow for a thinner thermal response barrier, potentially enabling manufacturers to either reduce cell dimensions or increase energy density by optimizing space for active materials. This shift could also result in smaller pack sizes thanks to decreased cooling requirements.
While GM aims to utilize a variety of cell formats for greater adaptability in its upcoming electric vehicles, the complexity of this new design may pose challenges in mass manufacturing. Other automakers like Tesla and BMW have opted for cylindrical cells for their next-gen models, favoring them for advancements in range and efficiency.
