Electrochemical performance and structural evolution of spray pyrolyzed Mn₃O₄ thin films in different aqueous electrolytes: effect of anions and cations.

ABSTRACT: This work presents the impact of cycling in different cationic and anionic aqueous electrolytes on the electrochemical storage performance of the Mn₃O₄ thin film electrode prepared using the chemical pyrolysis method. Studies on the as-deposited electrode confirmed the formation of Mn₃O₄ phase. Extensive electrochemical analysis was performed using Na₂SO₄, NaCl, Li₂SO₄, K₂SO₄, and MgSO₄ electrolytes to examine the influence of cations and anions on charge storage behaviour. Considerable changes were observed in the specific capacitances owing to different ionic sizes as well as hydrated ionic radius of the electrolyte ions. Accordingly, the electrode unveiled a good perf
