The global electrolytic manganese dioxide market attained a value of USD 1.96 Billion in 2025 and is projected to expand at a CAGR of 6.90% through 2035. The market is further expected to achieve USD 3.82 Billion by 2035, driven by tighter battery-grade specifications, long qualification cycles with battery makers, growing use in water treatment and oxidation processes, and regional sourcing policies that favour traceable manganese supply chains.
Manganese ore supply from Australia and South Africa sets the cost base for the industry. South32 reported in July 2026 that Australia Manganese produced 3,031 thousand wet metric tonnes in the year ended June 2026, up from 1,106 thousand a year earlier, while South Africa Manganese produced 2,085 thousand wet metric tonnes, 4% above guidance. For electrolytic manganese dioxide producers, a recovery in ore output eases feedstock availability, although conversion economics still depend on ore grade, electricity prices and the cost of meeting battery-grade impurity limits in refining.
Gabon is a second reading on manganese ore availability. Eramet reported in July 2026, for the six months ended June 2026, manganese EBITDA of EUR 209 million, up 6%, with 3.2 million tonnes of ore transported, up 6%, and external ore sales of 2.8 million tonnes, up 4%. Alloys production rose 11% to 359 thousand tonnes. These volumes show how much manganese feed is moving toward conversion plants, and they matter to producers that buy ore or intermediates and then refine them to battery-grade specifications.
Policy support for North American refining forms a third reading. Element 25 said in July 2026 that it had agreed terms with the US Department of Energy on an updated grant agreement for USD 166 million under the Battery Materials Processing Grant Program, tied to its planned high-purity manganese sulphate facility in Louisiana, which would draw on its Butcherbird manganese project in Western Australia, where an expansion targets about 1.1 million tonnes a year of concentrate. Public funding for local refining supports traceable battery-grade manganese supply and signals demand for qualified manganese chemicals.

By Application, Batteries leads the market while Water Treatment grows fastest because battery makers qualify manganese dioxide grades over long cycles, while treatment systems need consistent oxidation and contaminant removal
Batteries leads because alkaline and specialty cells rely on electrolytic manganese dioxide for stable discharge, and qualification cycles tie battery makers to approved suppliers. Energizer Holdings reported in May 2026 net sales of USD 643.3 million for the quarter ended March 2026, down 3.0%, with Batteries & Lights sales of USD 473.2 million, down 3.0%, and adjusted earnings of USD 0.94 per share. Softer consumer volumes moderate growth, yet replacement purchases keep battery makers the steadiest buyers of the material.
Water Treatment grows fastest because manganese dioxide supports oxidation and contaminant removal in municipal and industrial water systems. Pentair reported in July 2026 Water Solutions sales of USD 422.0 million for the quarter ended June 2026, down 5%, while segment income rose 17% to USD 126.4 million at a return on sales of 30.0%. Strong profitability in water treatment equipment suggests operators keep funding filtration upgrades, which supports demand for consistent oxidation media and reagents even when equipment sales fluctuate.
Asia Pacific commands the largest regional share of the electrolytic manganese dioxide market, shaped by its concentration of battery manufacturing, chemical processing and integrated manganese supply chains
This is supported by South32, which told investors in January 2026 that Australian manganese output rose 26% year on year after operations recovered from storm and cyclone damage, while South African output rose 4% after planned maintenance. A recovery of this size in Australia restores ore supply to the Asia Pacific processors that convert manganese into battery and chemical grades for battery makers and chemical users alike, and it reinforces the region's position as the centre of production and consumption.
North America is the fastest-growing regional market as battery supply chains shift toward regional sourcing. RecycLiCo Battery Materials said in April 2026 that Green Manganese, which is developing a low-carbon process to recover high-purity manganese from local sources, mining tailings and industrial waste for the steel and battery industries, is moving into its Innovation Centre in Delta, British Columbia. Europe, Latin America and the Middle East and Africa grow more gradually on compliance, niche industrial and water demand.
The global electrolytic manganese dioxide market is concentrated among a small group of qualified producers, with specialty chemical and battery material groups competing alongside regional producers, mainly in Asia, that supply battery and industrial customers under long-term contracts.
Competitive dynamics are shaped by specification control, impurity management, qualification depth with battery makers, access to manganese ore and low-cost power, trade remedies and localisation policies, and the ability to provide technical service and documentation to battery and water treatment customers.
Tosoh Hellas A.I.C. is the Greek electrolytic manganese dioxide operation of the Tosoh Group and lists an address in the Sindos industrial area, supplying European alkaline battery makers. In May 2026 Tosoh Corporation reported for the year ended March 2026 net sales of JPY 1,019.9 billion and operating income of JPY 95.5 billion, with electrolytic manganese dioxide shipments falling overall, rising in Europe and declining in Asia.
Mesa Minerals Limited was a Western Australian manganese developer with tenements in the Pilbara region, working to commercialise technology that converted low-grade manganese dioxide ores and manganese-bearing waste into electrolytic manganese and fertiliser products. Formerly HiTec Energy Limited, it was renamed in October 2009, entered administration in July 2016, and a court ordered its liquidation in October 2018.
Tronox Holdings plc produces titanium dioxide pigment, zircon and other mineral products. In January 2026 it announced the permanent closure of its Fuzhou, China, TiO2 plant, which had capacity of 46,000 tonnes a year and about 550 staff, citing weak Chinese demand and excess output, and released selected preliminary results for the quarter ended December 2025 alongside the announcement.
American Manganese Inc. now operates as RecycLiCo Battery Materials Inc., a Delta, British Columbia, company that refines critical minerals and upcycles lithium-ion battery materials, using hydrometallurgical processes to recover lithium, cobalt, nickel and manganese from end-of-life batteries and manufacturing scrap. In January 2026 it granted a director 3,000,000 stock options expiring in January 2031.
