Cathode Materials for Lithium-ion Batteries

Nichia has been developing and manufacturing cathode materials for Lithium-ion batteries, based on its core technologies in powder synthesis Nichia has built up during its many years as a leading phosphor manufacturer. By carrying out the entire manufacturing process from raw materials to final products, Nichia has also been swiftly serving various demands of its customers and consistently supplying solutions for Lithium-ion batteries that meet the demands of higher capacity and higher safety. Recently, Lithium-ion batteries are required to make further progress in accordance with their applications such as large-sized batteries with high reliability and high-power operation , and for portable devices with low price and high capacity.As one of world-leading manufacturer of cathode materials for Lithium-ion batteries, Nichia will continue to supply products with the optimum particle design in order to keep up with rapidly expanding applications for Lithium-ion batteries.

Ever-expanding Applications


Utilizing Nichia’s unique coprecipitation technique and performing atomic-level mixing, Nichia offers products with optimum particle design for various applications. Ternary cathode materials (NMC) have an advantage of reducing the use of Cobalt and achieving both excellent output and excellent safety, making them the optimum materials for large-size batteries (i.e. in-vehicle use). In the coming years, an exponential increase in demand is anticipated and Nichia is committed to the development of these key materials.

Applications: small mobile devices, notebook computers, electric power tools, large-size Lithium-ion batteries, in-vehicle batteries, etc.
