About Battery Material Development Center / Technology & Engineering Development Center
Lithium Battery Material Department aims to contribute to an electrified society through the development and commercialization of new materials for next-generation batteries, with a focus on solid electrolytes in all-solid-state lithium batteries, which are expected to be put to practical use as the next-generation secondary batteries.
At Battery Material Development Center / Technology & Engineering Development Center, we are developing solid electrolytes that have superior properties such as thermal stability compared to flammable electrolytes, which have been an issue with conventional liquid lithium batteries. All-solid-state lithium batteries using these solid electrolytes are expected to achieve both high energy density and safety, and to be long-lasting yet excellent for rapid charging.
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
R&D chemists, process development engineers, and equipment engineers are working together to develop manufacturing methods in order to establish the world's leading mass production technology for solid electrolytes. The demonstration facility began operation in the fall of 2021. We are promoting development with the aim of mass-producing solid electrolytes, further improving quality and reducing costs, and building an integrated production and stable supply system from raw materials.

Lithium recovery technology
With the predicted spread of EVs and other devices, the demand for lithium secondary batteries is expected to expand rapidly. As the raw materials used will also increase rapidly, the reuse and recycling of batteries is attracting attention. We are developing technology to recover lithium from used batteries for use in solid electrolytes of all-solid lithium battery.
Main initiatives/research contents - 04
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.
