Sustainability

A Sustainable Closed-Loop

The surge in demand for lithium batteries around the world means that more materials need to be recovered and recycled from used batteries. Idemitsu is developing technology to manage the recovery of battery materials and integrate them directly into our solid electrolytes. Idemitsu reduces the carbon footprint in manufacturing processes of battery materials by applying energy efficient processing steps, ensuring Idemitsu remains compliant with the highest environmental standards. Working together with our partners we will work towards a shared commitment to a circular economy.

Our vision is to integrate recovered materials directly into our solid electrolytes. We aim to manage the supply chain with our partners to reinforce our shared commitment to a circular economy.
