<p>Efforts to reduce the energy consumption, CO₂ emissions, and production costs associated with lithium-ion battery manufacturing have prompted researchers to find alternatives to energy-intensive conventional oven drying. Towards this goal, we developed a method based on flashlight drying as a rapid, efficient approach, and succeeded in reducing the drying time and energy consumption to produce graphite composite anodes by 90% and 88.3%, respectively. In addition to its efficiency, this method uniquely induces surface activation not observed with oven drying to significantly enhance the electrochemical performance of the electrodes. Compatibility with the roll-to-roll (R2R) process is further demonstrated using a custom-designed R2R system integrated with a flashlight module to confirm its suitability for continuous production lines. Overall, flash drying is demonstrated to be a viable replacement for conventional drying methods in that it leads to substantial energy savings and improves the electrode performance. These improvements can be expected to ultimately lower the production costs to enable more sustainable, high-performance manufacturing for lithium-ion batteries.</p>
