BUILDING A BETTER FUTURE THROUGH CONVERGENCE
Soulbrain is stably supplying small-capacity (secondary) battery materials, and we are increasing our competitiveness in the secondary battery market through development of next generation large-capacity battery materials. We are manufacturing electrolyte and lead tabs, key materials in secondary batteries, and supplying materials both domestically and abroad, and we are also focusing on the development of medium-capacity (next generation) secondary battery materials.
Electrolyte, one of the key components of lithium ion secondary batteries, is a medium enabling the movement of lithium ions between the anode and cathode. Non-aqueous electrolytes are composed of organic solvents with high electric constants and low viscosity, lithium salts, and additives. Based on refined technology for differentiated solvents and additives, Soulbrain has developed a manufacturing process maintaining low moisture and HF content, and we are manufacturing high quality electrolytes. In addition, we are developing and supplying a variety of functional electrolytes to improve the lifetime and performance of secondary batteries, such as electrolytes with gas generation controlling and overcharge prevention capabilities.
Lead tabs for lithium ion secondary batteries are materials connecting the anode and cathode in the pouch, and are made of metals such as aluminum, nickel, and coppers. The Lead Tab Business Division of Soulbrain’s subsidiary, Materials Park Co., Ltd., is manufacturing high quality products which can perfectly block the leakage of electrolyte, through differentiated electroplating technology and surface coating technology. In addition, we are equipped with facilities which can supply a variety of products based on an automated production line capable of manufacturing products of to a variety of specifications.
