Description

General description

Manganese(II) carbonate is a chemical compound that has a structure similar to calcite, with octahedral co-ordination symmetry. It is a carbonate that is insoluble in water and on treatment with acid it gives water soluble salts. It is a widely used material in plant fertilization as an additive that cures the magnesium deficiency in crops.

Application

Manganese(II) carbonate can be used as:      

• A primary electrode material in asymmetric supercapacitors for improving the charge storage capacity and overall performance of the supercapacitors.      
• A precursor for synthesizing manganese oxide, which is used as a component in various electrochemical applications, including batteries and supercapacitors.    
• A precursor material in the synthesis of oxygen vacancy-rich nitrogen-doped manganese carbonate (MnCO₂@N) microspheres. These microspheres are then employed as cathode materials in aqueous zinc-ion batteries (ZIBs) to enhance their electrochemical performance.
• A potential electrocatalyst for the oxygen evolution reaction (OER) in water splitting applications.
