Project Name: Dry Electrode Supercapacitor Production Line
Description: XIAMEN TOB NEW ENERGY TECHNOLOGY CO., LTD. designed and established a 60138 supercapacitor production line which is using dry electrode process for the customer's battery factory, and TOB New Energy provides a full set of production technology, production line equipment, raw materials and supplies of various consumables.
Date: From January 2021 to January 2023
Location: North America
The traditional cathode and anode electrode manufacturing process of lithium batteries usually requires the use of a solvent containing a binder, which is mixed with a conductive agent to form a slurry. The slurry is then coated on copper or aluminum foil, and the solvent is evaporated by drying. In the electrode manufacturing process, the manufacturing cost of coating and drying links accounts for about 54%. Moreover, the toxicity of the solvent is high, and the manufacturing process is not environmentally friendly. The dry electrode technology is performed in a solvent-free manner, through dry powder mixing, powder film formation, and then integrated into the current collector layer of copper foil or aluminum foil on the basis of the film, which is not only lower in manufacturing cost but also more environmentally friendly. On the one hand, they want to try to use this feasible new technology in the battery field to expand their product categories, and on the other hand, they can also accumulate technical experience for subsequent research in other directions.
