IMnI Annual Review (battery-manganese demand)

International Manganese Institute (IMnI)

World manganese demand across all battery types: ~370 kt contained Mn in 2025, the industry body's own estimate - the platform's only world manganese demand figure. Citable context carried here (not emitted as records): 2025 world production SiMn ~16.4 Mmt (China 68%), HC FeMn ~4.0 Mmt, Ref FeMn 1.8 Mmt record, EMM 1.44 Mmt, Mn ore 21.4 Mt contained Mn (SA 46%/Gabon 19%/Australia 9%)

Quirks

ONE ROW BY DESIGN: both free Annual Review editions were read page by page (2026-08-04) and the SiMn / HC FeMn / Ref FeMn production-and-demand SERIES charts are unlabelled bars - numbers are never transcribed off unlabelled bars (the ILZSG lead-factbook precedent). The granular series are member products, out of license scope
per-class production levels are gross-product basis with distinct Mn contents - never summed across classes, and deliberately not emitted as supply records (a basis-mixing decision no one has made)
