PowerGenix Nickel-Zinc Technology Overview

PowerGenix has developed a high-energy density, high-cycle life and low-cost nickel-zinc (NiZn) battery ideal for applications that demand high discharge rate capabilities.

The technology offers compelling performance advantages, most notably a 30% weight and size reduction coupled with higher power and superior low temperature discharge behavior.

Using both a patented electrolyte and a patented electrode composition, PowerGenix has eliminated past issues of dendrite formation and shape change of the zinc electrode during cycling. Dendrite formation and shape change of the zinc electrode have been the primary hindrances to a commercially viable rechargeable NiZn battery. Additionally, PowerGenix developed this breakthrough technology in a manner that did not compromise the inherently superior performance characteristics of a NiZn battery.

Two of the more prominent features of the PowerGenix NiZn battery are its small size and low internal resistance, which enables the delivery of significantly more power during periods of peak demand than a nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) battery of comparable size.

Although the design and construction of the cell is similar to NiCd, the higher voltage of PowerGenix's NiZn cell results in a 25% lower cell requirement in multi-cell packages, representing significant space and cost savings.
