Battery Materials Department
The Battery Materials Department provides the main materials of lithium-ion batteries: cathode materials, anode materials, formulated electrolytes and separator. Our cathode materials, NMCO7 and NMCO5, are the ternary system of manganese, nickel, and cobalt. The anode materials, MPG and ICG, are graphite-based products. The Sol-Rite ™ formulated electrolytes have the capability to generate a solid electrolyte interface on the electrode surfaces. The separators are polypropylene membranes with three-dimensional network of micropore. Mono-layer and tri-layer types are available.

NMC05 and NMC07, cathode materials for lithium-ion batteries, are the ternary system of nickel, manganese and cobalt with the composition of Ni/Mn/Co=33/33/33 and 45/45/10, respectively. Reducing the expensive cobalt to 10% by our proprietary technology, NMC07 achieves the output power equivalent to NMC111 and the durability superior to NMC111.
MPG (natural graphite-based materials) / ICG (artificial graphite-based materials)
Mitsubishi Chemical provides two types of anode materials for lithium-ion batteries: MPG, natural graphite-based materials and ICG, artificial graphite-based materials. MPG shows excellent performance under rapid charging and discharging cycles. ICG has large capacity with improved battery life.
Sol-Rite™, formulated electrolytes in organic solvents, are mainly used for lithium-ion batteries. It is also used for primary lithium batteries and aluminum electrolytic capacitors. Functional additives in the formulation improve battery performance significantly. Sol-Rite™ is the trademark of Mitsubishi Chemical Corporation.
SEPALENT™, separators for lithium-ion batteries, are polypropylene (PP) micro-porous membranes. The three-dimensional micro-pore structure of SEPALENT™ improves safety, output, and lifetime of lithium-ion batteries.
