This ultra-pure form ensures consistent electrochemical performance in battery applications.

Key physical properties include:

• Solubility in water: Highly soluble (520g/L at 20°C)
• Melting point: Decomposes at temperatures above 850°C
• Density: 2.95 g/cm³ (anhydrous form)
• pH: Slightly acidic (3.0-5.0 in aqueous solution)
• Appearance: Fine crystalline powder with particle size distribution typically between 10-50 μm

The compound's stability in ambient conditions makes it ideal for manufacturing processes, allowing for consistent quality in battery material production lines.

Critical Applications in Modern Battery Technology

The primary value of high-purity manganese sulphate lies in its role as a precursor for lithium-ion battery cathode materials, particularly in nickel-manganese-cobalt (NMC) and lithium-manganese oxide (LMO) chemistries. According to SMM Analysis (2025), HPMS serves three critical functions in battery applications:

1. Energy Density Enhancement: Manganese-containing cathodes deliver higher energy density compared to alternative chemistries, enabling longer-range electric vehicles.

2. Battery Life Extension: The incorporation of manganese in proper proportions helps stabilize battery structure during charge-discharge cycles, extending service life.

However, as SMM Analysis (2025) confirms, the battery sector continues to dominate demand, with other applications representing less than 15% of total HPMS consumption.

How Is the High-Purity Manganese Sulphate Market Performing in 2025?

The high-purity manganese sulphate market is experiencing notable headwinds in 2025, with SMM Analysis confirming a decline in total demand for high-purity manganese sulphate compared to previous years. This downturn represents a significant shift from the explosive growth seen in the early 2020s, when electric vehicle production was accelerating at double-digit rates annually.

Current Market Conditions and Demand Trends

According to the latest SMM Analysis (2025), inventory levels of major domestic producers have increased year-over-year, indicating a supply-demand imbalance in the market. This inventory buildup reflects both production capacity expansions initiated during more optimistic market periods and the current reality of slowing demand growth.

Market conditions vary significantly by region:

• Europe: Showing more stability due to stricter local content requirements for battery materials
• North America: Benefiting from government incentives but still facing demand shortfalls
• Asia (excluding China): Mixed performance with stronger positions in countries with established battery manufacturing

The price trajectory for high-purity manganese sulphate has followed this supply-demand imbalance, with downward pressure becoming evident in early 2025. While exact figures vary by region and contract terms, the general trend shows a 15-20% reduction from peak 2023 prices.

"The total demand for high-purity manganese sulphate will decline in 2025, with increasingly fierce market competition as inventory levels continue to rise." – SMM Analysis, 2025

Key Factors Driving the Demand Decline

The SMM Analysis (2025) identifies several specific factors contributing to the current market challenges:

1. Underperformance in Downstream Production: The ternary cathode precursor industry has fallen short of projected growth targets. This sector represents the primary demand driver for high-purity manganese sulphate, and its underperformance has directly impacted HPMS consumption.

2. Shift Toward High-Nickel Cathode Materials: The rapid development and adoption of high-nickel ternary cathode materials have reduced manganese requirements per battery unit. Modern NMC 811 cathodes (containing 80% nickel, 10% manganese, and 10% cobalt) use significantly less manganese than earlier NMC 111 or NMC 532 formulations.

3. Sodium-Ion Battery Commercialization Delays: While sodium-ion batteries represent a promising technology that would utilize manganese-based cathodes, their commercial deployment has progressed more slowly than anticipated, delaying a potential new demand source.

4. LMFP Technology Development Challenges: Lithium Manganese Iron Phosphate (LMFP) battery technology, which initially showed promise as a manganese-intensive alternative to LFP batteries, has encountered technical hurdles that delayed widespread adoption.

The table below illustrates the changing manganese content in evolving cathode chemistries:

This shift toward lower manganese-content chemistries has had a multiplier effect on HPMS demand reduction, as each gigawatt-hour of battery production now requires substantially less manganese input than previously anticipated.
