Mitsubishi Chemical Kagawa Plant Natural-Graphite Anode Line

Mitsubishi Chemical Corporation announced in December 2024 an 11,000 tonne/year capacity increase for natural graphite-based anode material for EV lithium-ion batteries at its Kagawa Plant in Sakaide, Kagawa Prefecture, with expanded operations to start in October 2026 (tentative). The company cites a low-GHG manufacturing process and a proprietary grade that suppresses natural graphite's swelling to address battery-longevity issues. The coverage manifest links this facility to Japan's ESPA (Economic Security Promotion Act) approved storage-battery supply assurance plans, but METI's nintei.pdf list returned HTTP 403 during this curation pass, so the ESPA linkage remains UNVERIFIED and is deliberately not recorded as a claim — this record cites only the company releases. Modeling notes: the record covers the announced expansion line; the 11,000 t/y capacity claim is the announced increase, not total site capacity. The input intermediate is not named by the sources, so the input flow uses uncoated-spherical-graphite as an inferred mapping, and the 'natural graphite-based anode material' output is mapped to the coated-spherical-purified-graphite token.
