Abstract

A novel Zn-MnO₂ battery ststem by use of spinel related MnO₂ as positive electrode and Zn(ClO₄)₂ in propyl carbonate as electrolyte was constructed and its charge discharge behaviour was studied. The results show that the cell reaction of the system proceeds through the electrochemical intercalation of zinc into the crystalline lattice of MnO₂ to form Zn_xMn₂O₄. At x≤0.5, Zn_xMn₂O₄ onstrates excellent cycleability (>200 cycles), higher discharge charge efficiency (>90%) and prolonged storage life.
