New Idea for Battery Manufacturing: A Simple Press to Accelerate Electrolyte Wetting Press & Wet: A "Sponge-Inspired" New Strategy for Pouch Battery Electrolyte Wetting In the manufacturing process of lithium-ion batteries, electrolyte injection and wetting is an often-overlooked yet crucial step. The electrolyte must fully penetrate the separator and the interior of porous electrodes to form stable ion-conducting pathways, providing an efficient and safe operating environment for the battery. However, the electrolyte wetting process is typically extremely slow—even in automated production lines, it often takes 24 to 48 hours to complete. This not only severely slows down the production rhythm but also significantly increases manufacturing costs. A research team from
