■ AI-SUMMARIZED FROM 5 SOURCES ▸ TIMELINE

SoftBank Group plans to manufacture lithium- and cobalt-free batteries for data centers in Japan by fiscal year 2027. The move aligns with Japan's broader strategy to reduce dependence on Chinese metal supplies.

SoftBank's battery initiative targets the data center sector, which typically relies on lithium-ion technology that depends heavily on cobalt and lithium sourcing. By developing alternatives domestically, the company aims to address supply chain vulnerabilities while supporting Japan's critical mineral independence. The timing matters as global demand for data center power solutions accelerates due to AI and cloud computing expansion. Japan has increasingly focused on reducing reliance on Chinese metal exports, particularly for strategic technologies. Details on the specific chemistry or technology SoftBank will use remain limited. The FY2027 target—Japan's fiscal year ends March 31, 2027—gives the company approximately three years to scale production. Success could position SoftBank as a supplier for domestic and potentially regional data center operators seeking supply chain alternatives.
