Manganese occupies a peculiar position in the commodity world. It’s the fourth most-used metal globally by tonnage, essential to virtually all steel production, and was once hailed as a key beneficiary of the EV revolution. In April 2026, that narrative is fracturing — and the market implications are significant.

Steel: The Bedrock of Manganese Demand

Approximately 90% of all manganese consumed globally goes into steelmaking. Manganese is a critical alloying element that removes sulfur and oxygen during steel processing and improves strength, hardness, and wear resistance. There is no commercially viable substitute for manganese in steel production at current technology levels.

This steel dependency means manganese demand tracks global steel output closely. In early 2026, the steel picture is mixed. Chinese steel production — roughly half of global output — has been under policy pressure as Beijing continues to push decarbonization targets for heavy industry. European steel output remains below pre-pandemic levels. Bright spots include India, where infrastructure investment is driving steel consumption growth in the high single digits annually, and Southeast Asia, where construction activity is expanding.

The net effect: steel-driven manganese demand is growing slowly but steadily, providing a demand floor that prevents dramatic price collapses.

The EV Battery Pivot — Away from Manganese

The growth narrative for manganese centered on its role in lithium-ion battery cathodes. NMC (nickel-manganese-cobalt) cathode chemistry was projected to dominate the EV battery market, with manganese comprising roughly 10-15% of cathode weight in NMC 622 and NMC 811 formulations.

That thesis has weakened considerably. Several trends are working against manganese-intensive battery chemistries:

LFP dominance: Lithium iron phosphate (LFP) batteries — which contain zero manganese — have gained massive market share. BYD, CATL, and Tesla have all shifted significant production volume to LFP chemistry for standard-range EVs. LFP’s advantages in cost, safety, and cycle life have proven more commercially important than NMC’s energy density advantage for the mass market.

Sodium-ion emergence: CATL and BYD have begun commercial deployment of sodium-ion batteries for low-cost EVs and energy storage. These batteries use no manganese, lithium, cobalt, or nickel — a complete bypass of the traditional battery metals complex.

LMFP still niche: Lithium manganese iron phosphate (LMFP) chemistry — which does include manganese — has been positioned as a next-generation upgrade to LFP. However, commercial adoption has been slower than projected. Manufacturing challenges and the adequacy of existing LFP performance have limited LMFP’s market penetration.

Supply Concentration Risk

Manganese mining is heavily concentrated. South Africa produces approximately 37% of global manganese ore, followed by Gabon (18%), Australia (17%), and China (9%). This concentration creates supply vulnerability:

• South African mining faces persistent challenges with electricity supply (Eskom load-shedding), rail logistics (Transnet performance), and port capacity at Saldanha Bay
• Gabon’s Comilog mine (owned by Eramet) is a single-point-of-failure for a significant share of global high-grade manganese ore
• Australia’s South32 operations in the Groote Eylandt mine provide high-quality ore but face indigenous land rights negotiations and environmental reviews

Processing is even more concentrated, with China controlling an estimated 90%+ of global electrolytic manganese metal (EMM) and manganese sulfate production.

Key Risk Factors

• Chinese steel policy: Any acceleration of steel production cuts under decarbonization mandates directly reduces manganese demand
• Battery chemistry evolution: Further LFP gains or sodium-ion scaling would diminish the EV-driven manganese growth thesis
• South African logistics: Transnet rail and port disruptions periodically squeeze manganese ore supply and create price spikes

What to Watch

1. Chinese monthly steel production data (NBS) — the single largest driver of manganese consumption globally
2. CATL and BYD quarterly battery chemistry mix disclosures — reveals the actual trajectory of LFP vs. NMC vs. sodium-ion adoption
3. South Africa’s Transnet rail performance metrics — logistics bottlenecks are the most common trigger for short-term manganese price volatility

Signal Summary

Manganese in April 2026 is a commodity caught between a reliable but slow-growth steel demand base and a fading EV battery growth narrative. The supply side remains structurally concentrated and vulnerable to disruption, which provides episodic price support. But the long-term demand excitement that drove investor interest in manganese during 2021-2023 has cooled significantly. This is a market that rewards patience and logistics awareness more than directional conviction.
