Lithium Battery Material Department
Regarding Lithium Battery Material Department
Lithium Battery Material Department is developing and establishing a mass production system for solid electrolytes, which are key materials for all-solid lithium battery that contribute to the evolution of mobility and the creation of a Resources recycling society. In addition, we are working on the development of "Catholite," Functional materials that fuses solid electrolytes and cathode materials, and sulfur-based cathode materials.
We will advance these initiatives with the aim of implementing all-solid lithium battery in provide for society.
Main initiatives/research contents - 01
Development of solid electrolytes materials
We are working to improve the performance of solid electrolytes in all-solid lithium battery, and to develop manufacturing processes for these materials, with the aim of commercializing them.
We continue to propose and improve materials to each of our partner companies, and continue to refine our materials.
Main initiatives/research contents - 02
Efforts toward mass production
We currently operate two Small-scale verification facility. We have also decided to construct Large pilot facility with the aim of establishing mass production technology. Furthermore, we have decided to construct Lithium sulfide production facility an intermediate raw material for solid electrolytes. We are steadily progressing in building an integrated value chain from raw materials to finished products.

Development of next-generation cathode materials
To strengthen the materials value chain for electrification and motorization, we are working on developing not only solid electrolytes but also cassolite and sulfur-based cathode materials. We are currently developing "cassolite," Functional materials that fuses solid electrolytes and cathode materials, in collaboration with Umicore in Belgium. Furthermore, sulfur-based cathode materials are materials that support the realization of all-solid-state lithium-sulfur batteries, which have the characteristics of being lightweight, high-capacity, and rare-metal-free, and these batteries are expected to be a strong candidate for second-generation all-solid lithium battery.

Intellectual property strategy activities
We are currently considering strategically acquiring our intellectual property in order to commercialize solid electrolytes.
Our proprietary lithium sulfide industrial production technology and sulfide-based solid electrolytes made from lithium sulfide have led to many inventions and the number of patent applications in this field is among the highest in the world. We will continue to contribute to commercialization by pursuing the rights to the technologies we develop.
