Battery Materials

We contribute to the realization of a sustainable society with electrolytes and additives for lithium-ion rechargeable batteries.

The popularization of mobile devices such as smartphones and laptops and environmentally friendly electric vehicles (EVs) around us is supported by light, high-capacity lithium-ion rechargeable batteries. Kanto Denka Kogyo is the only manufacturer in Japan that manufactures electrolytes and additives essential for lithium-ion rechargeable batteries.
As the global trend towards decarbonization and EV shift accelerates, we continue our contribution to the creation of a sustainable society by leveraging our world-class quality and supply capabilities and working with reliable partner companies.

KDK’s battery materials are used in information terminals such as smartphones and batteries in electric vehicles.
