Product List

Battery Internal Materials

Iwatani imports and sells materials, including lithium, cobalt, nickel, and manganese, for cathode active materials in lithium ion rechargeable batteries, which show promise for next generation vehicle applications. In addition to cathode materials, we handle a wide range of battery materials, including anode active materials, metal materials, and conductivity-boosting agents.
Cylindrical Battery Materials

Characterized by high capacity discharge, cylindrical batteries incorporate materials that require high machining precision. Iwatani operates a precision machining plant for metal materials in China, drawing on ultra-precise slitting capabilities to provide a wide range of aluminum, nickel, clad, and copper foil materials for use as battery leads.
Square Battery Materials

Offering high strength and energy density, square batteries incorporate thermally insulating and heat dissipating materials. Iwatani handles a wide range of sheets, potting materials, and adhesives for use with these thermally insulating and heat dissipating materials. We offer materials that meet thermal design requirements for vehicle and consumer batteries.
Pouch Battery Materials

Pouch batteries are lightweight and offer greater freedom of shape formation compared to cylindrical and square batteries, and are hence widely used in EV and mobile device applications. Iwatani handles taper processed metals for tab leads and acrylic forms for EV batteries, utilizing our unique technology and processing capabilities.
Subsidiary Materials for Batteries

In addition to cathode active materials and structural materials, including films and metals for rechargeable batteries, Iwatani handles various subsidiary materials for batteries, including filters, lubricants, and doctor blades. Through offering high performance materials, Iwatani contributes to optimizing customer’s manufacturing processes.
