Japan achieves 90% lithium recovery in EV battery recycling

Japanese firms and government ministries have developed recycling processes capable of recovering 90% ^[1] of lithium from used electric vehicle batteries.

This breakthrough addresses the critical shortage of rare metals needed for green energy transitions. As the global demand for EVs grows, the ability to reclaim materials from old batteries reduces reliance on volatile foreign mining markets.

The progress centers on a recycling facility in Tsuruga, Japan ^[1]. Engineers there have focused on upcycling and extraction methods that overcome the technical difficulties associated with traditional battery disposal. These processes allow for the efficient recovery of lithium, a metal essential for the high-capacity batteries that power modern transport ^[1], ^[3].

Beyond the technical achievements, the Japanese government is moving to formalize the battery lifecycle. Officials have drafted a policy proposal that would create a mandatory collection requirement for carmakers ^[2]. This would compel automotive companies to take responsibility for the batteries once they reach the end of their functional life, ensuring a steady stream of raw materials for the Tsuruga plant and similar facilities.

The push for these systems is driven by the rising cost and scarcity of rare metals ^[3]. Traditional recycling methods have often been too expensive or inefficient to be viable at scale. By increasing the recovery rate to 90% ^[1], Japan aims to create a circular economy where the automotive industry can sustain its own material needs without constant new extraction ^[2], ^[3].

Government ministries continue to collaborate with private carmakers to integrate these recovery systems into the broader industrial strategy. The goal is to stabilize the supply chain for the next generation of electric vehicles while mitigating the environmental impact of battery waste ^[2].
