Dry Electrode Production Equipment Electrode R&D

The dry film preparation technology avoids the use of any solvent in the preparation of lithium batteries, thus solving the following problems: G. Dry Electrode Production Equipment Lithium Metal F. Preparation Equipment Calendering machine Lithium strip calendering Winding, unwinding and release film forming Lithium/Copper Laminator Lithium copper strip rolling combination and coiling Low tension control Realize the coiling of ultra-thin lithium strips Lithium copper strip combination and coiling Lithium alloy mixing Fully sealed argon gas protection glove box Casted into ingots Lithium ingot casting Cost reduction: Dry electrode technology saves solvents, as well as the cost of solvent evaporation, recovery, and drying equipment. Inhibition of layering: Dry electrode technology does not use solvents during the mixing process of electrode components. Therefore, during the dry mixing process, due to the shear and friction of the mixer and particles, different components of the electrode material can be evenly distributed. Moreover, due to the absence of slurry during the dry mixing process, there is no longer electrode layering caused by solvent evaporation. No restrictions on electrode thickness: dry film technology can easily control electrode thickness and uniformity of thick electrodes, without generating cracks. It has unique advantages in preparing thick electrodes. Compatible with sulfide solid-state electrolytes: Dry film technology avoids the use of organic/polar solvents and only requires a small amount of adhesive during the film making process, making it particularly suitable for preparing sulfide all solid-state batteries. The dry film preparation technology is helpful in preparing solid-state sulfide electrolyte film and maintain its high ionic conductivity, as it does not involve the use of solvents that react with sulfide solid-state electrolyte
