Rechargeable molecular cluster batteries

Abstract
We fabricated a rechargeable molecular cluster battery, based on a cathode active material, [Mn12O12(CH3COO)16(H2O)4]. The charging–discharging experiments revealed rechargeable battery performance with a capacity of ca. 90 A h kg−1, while the first discharging process exhibited an extremely high value of 200–250 A h kg−1.
