In the manganese-based hydrometallurgy industry chain, sulphuric acid is not merely an ordinary auxiliary material, but rather a core lifeline raw material that runs through the production of all product categories, controls production costs, and influences process selection. Mainstream products such as EMM, various grades of manganese sulphate, and EMD differ vastly in production processes and have entirely distinct acid consumption structures, which also leads to completely stratified sensitivities of various manganese products to sulphuric acid price fluctuations. Every round of change in acid prices transmits from top to bottom, directly reshaping the cost structure and market dynamics of the manganese industry chain.

Recently, China’s manganese-based battery materials market has shown an overall pattern of cost-driven dynamics, product differentiation, and gradually recovering demand. Manganese sulphate and Mn3O4 were supported by rising upstream raw material costs and freight rates, with prices trending upward; MnO2 remained stable; LMO held steady amid fluctuations in lithium carbonate, awaiting a recovery in demand in April.
