FAQ
Q1: How does battery grade manganese sulfate compare to MnO in precursor synthesis?
A1: MnSO₄ dissolves readily in water, offering uniform Mn distribution and accurate stoichiometry, unlike MnO, which has lower solubility and slower reaction kinetics.
Q2: Why are Fe, Ca, and Mg impurities critical in battery-grade MnSO₄?
A2: These impurities can affect cathode crystal structure and electrochemical performance. Low levels ensure high-purity NCM precursor production.
Q3: What are the heavy metal limits for battery applications?
A3: Pb ≤ 2 ppm, Cu ≤ 1 ppm, Zn ≤ 1 ppm, ensuring compliance with battery-grade safety standards.
Q4: Can this MnSO₄ be used for other lithium-ion cathode materials?
A4: Yes, it is suitable for various lithium-ion cathode chemistries requiring high-purity manganese, including LMO and LMFP precursors.
Q5: How stable is this product during storage?
A5: Stored in dry, ventilated conditions, the product maintains consistent Mn content and low impurity levels for extended shelf life.
