Capacitance effects superimposed on redox processes in molecular-cluster batteries: a synergic route to high-capacity energy storage.

Rechargeable molecular-cluster batteries (MCBs) based on the manganese cluster complex [Mn12 O12 (CH3 CH2 C(CH3 )2 COO)16 (H2 O)4 ] ([Mn12]) that exhibited a capacity of approximately 200 A h kg(-1) in the battery voltage range of 4.0 to 2.0 V were developed.

Molecular cluster batteries of nano-hybrid materials between Keggin POMs and SWNTs.

Nano-hybrid materials of single-walled carbon nanotubes (SWNTs) and polyoxometalates (POMs) with three counter cations were prepared and used as cathode-active materials of molecular cluster batteries (MCBs). The charging/discharging performances and thus battery capacity of the MCBs with hybrid materials were significantly better than those of the microcrystal-POM MCBs.
