Rechargeable zinc manganese dioxide batteries are based on the same tried and tested chemistry as the familiar household AA alkaline cell.

Investments in the technology at City College of New York, starting in 2008 under Professor Sanjoy Banerjee, have helped bring this traditionally primary (single use) chemistry to the secondary (rechargeable) battery market, through physical changes to the cell and doping agents added to its chemistry.

Designed in a modular fashion, the cells are now being mass-produced at the Urban Electric Power factory in Pearl River, New York.
