Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

Sizing starts from electrolytic manganese dioxide production tonnage by grade, alkaline, zinc-manganese, and lithium-ion, split by region, and the realized per-tonne price each grade commands. Battery-grade tonnage is built from primary and rechargeable cell production volumes multiplied by the EMD content per cell type, while the industrial and water-treatment grade volume is built from municipal and industrial oxidation-media consumption. That unit-and-price build is then checked against the manganese chemicals segment revenue disclosed by producers such as Tosoh and Tronox in their own financial filings; where a producer's disclosed segment revenue implies a different tonnage than the bottom-up volume assumption, the volume or price assumption feeding the build is corrected rather than averaged against the disclosed figure.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary research targets commercial and technical roles inside EMD producers and their direct battery-cell and water-treatment customers, procurement and sourcing managers at battery pack assemblers, and channel partners who distribute EMD to smaller regional buyers. Regulatory and trade contacts are included where manganese ore import or environmental permitting affects production capacity. Sampling weights Asia Pacific most heavily given the concentration of both EMD production and battery cell manufacturing there, with additional coverage in North America and Europe to capture automotive and water-treatment demand-side views, and a smaller sample in Latin America and the Middle East and Africa where ore supply and downstream demand are both present but smaller in scale.

Secondary sources, this report

Secondary research draws on manganese dioxide trade flows recorded under HS code 2820.10, manganese ore production and trade statistics published by producing countries and by the International Manganese Institute, and the annual reports and segment disclosures filed by Tosoh, Tronox, and Eramet. Primary battery shipment volumes are checked against data published by battery industry associations such as the Battery Association of Japan and NEMA's battery section in the United States, and water treatment capacity additions are checked against municipal and industrial infrastructure investment records published by national water utilities and environmental agencies.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built from separate growth curves for each battery chemistry's EMD intake, primary and zinc-carbon cell demand tracked against population and electrification access in emerging markets, and manganese-based lithium-ion cathode adoption tracked against announced cell manufacturing capacity additions. Water treatment demand is forecast from municipal and industrial capacity expansion plans, not from the historical shipment trend alone. Pricing carries forward the pass-through relationship between manganese ore cost and EMD selling price observed across the historical period, and the 2020-2021 production disruption is treated as an anomaly normalized out of the trend line rather than a new baseline. The forecast holds if lithium-ion cathode capacity additions proceed roughly as currently announced.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Outputs are back-tested by holding out the two most recent historical years, rebuilding the forecast from data through 2022, and comparing the implied 2023 and 2024 values against what actually occurred by grade and region. Segment share shifts, particularly the pace at which lithium-ion battery grade gains share from alkaline grade, are reviewed against announced battery cell capacity additions instead of being accepted as a straight-line trend. Sensitivities are tested on the manganese ore price assumption and on the EMD content per battery cell, since both feed the bottom-up build directly, and the range of outcomes under each is checked against the bull and bear scenarios before they are finalized.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest for alkaline and zinc-manganese battery grade demand in North America, Europe, and East Asia, where production tonnage and battery cell shipment data are both well recorded. It is weaker for lithium-ion battery grade revenue, where manganese-based cathode adoption is still early and disclosed cell-level chemistry mix is limited, and for water treatment demand in Latin America and the Middle East and Africa, where capacity expansion plans are less consistently published. A structural risk that would force a revision is a faster-than-assumed shift away from manganese-based cathodes toward alternative chemistries in new lithium-ion cell designs.
