Zinc Manganese Dioxide

UEP's Zinc Manganese Dioxide battery revolutionizes the traditional single use alkaline chemistry for rechargeable energy storage systems with high energy density, long life and flexible performance ranging from 2-8 hours charge/discharge capabilities. There exists a real need for stationary energy storage to enable the widespread use of intermittent renewable energy sources and to eliminate the use of fossil-fuel-based solutions. Such storage must be easy to site, inexpensive, and durable. To date no technology has emerged as a universal solution, and those successfully implemented have significant drawbacks. That is, until now. 

The UEP technology concept was originally funded under the competitive Department Of Energy ARPA-E GRIDS program in 2009 and was based on research being conducted at the CUNY Energy Institute under the guidance of distinguished Professor Sanjoy Banerjee.  UEP was formed in January 2013 to license the technology and commercialize the battery product to bring to market. UEP’s battery systems are modular and scale to meet every stationary energy storage need, from residential to commercial to grid.


UEP’s zinc-manganese dioxide (Zn-MnO2) battery technology utilizes the same material as primary alkaline batteries, like the standard double AA. Revolutionizing the chemistry into rechargeable systems with high energy density and long cycle life.


Zn-MnO2 batteries use safe, non-toxic materials without lead, other heavy metals, or flammable electrolytes. They are recycled using similar processes developed for primary alkaline batteries.


UEP is scaling up production with a pilot manufacturing line in the previous Pfizer campus of Pearl River, NY - revitalizing jobs and manufacturing efforts in the Mid-Hudson Valley for US installations and exports across the globe.
