4680 Thermal Design And Management // Why Ribbon Cooling Is Better Apr 2026

According to The Limiting Factor, ribbon-based side cooling for Tesla’s 4680 cells provides superior thermal management compared to traditional bottom cooling by increasing surface area contact, which lowers peak temperatures and ensures better uniformity. This approach optimizes the 4680's tabless design to manage higher heat output, thus supporting faster charging and improved battery longevity.
