The next-generation large-capacity HEV and EV electrolyte businesses will be consistently promoted

Home > Business > Secondary Battery

Soulbrain will continue to develop and strengthen the secondary battery materials business for IT and xEV.

Electrolyte

The non-aqueous electrolytes for the secondary lithium battery are composed of the diverse organic solvents, lithium salts, and various additives to improve the battery performances. Soulbrain have the techniques to purify the solvents and additives, and is producing high-quality electrolytes by developing a manufacturing process to keep moisture and HF level low. Soulbrain provides various functional electrolyte solutions, which can improve battery lifetime and performance by suppressing gas formation and preventing over-charge.
