Rechargeable Nickel-Zinc (NiZn) Batteries offer many compelling benefits for the high-growth hybrid electric vehicle (HEV) market, providing a smaller, lighter and more powerful alternative to incumbent rechargeable battery technologies. Nickel-Zinc Battery offers superior energy and power density compared to lead-acid and Nickel-Metal Hydride (NiMH) batteries and avoids the high costs and safety issues associated with Lithium-ion (Li-ion) batteries. Additionally, Nickel-Zinc Batteries are the most recyclable rechargeable battery chemistry on the market. Nickel-Zinc Battery contains zero lead, cadmium, mercury or other rare earth metals. NiZn batteries’ inherent high power density and discharge rate make this technology an ideal solution for automotive applications that demand a large quantity of power in a small and lightweight package.

PowerGenix, the leading manufacturer of high performance rechargeable Nickel-Zinc (NiZn) batteries, now entered into the burgeoning micro-hybrid electric vehicle market with its first production prototype product. The company holds 23 patents (granted and pending) on Nickel-Zinc batteries. PowerGenix has begun engineering qualification activities for the new battery with several automotive OEMs and will be fielding demonstration vehicles later 2011. A more powerful and robust alternative to lead-acid batteries currently used in these “start/stop” hybrids, PowerGenix’s NiZn batteries offering is well positioned to dominate the multi-billion-dollar market opportunity.

Micro-Hybrid Electric Vehicles (HEV) are conventional cars with automatic start-stop technology – are the simplest automotive hybrid system and one of the most cost-effective ways to improve fuel economy and reduce automotive carbon emissions. In a micro-hybrid, the engine shuts off when the vehicle is stopped, providing a 5 to 8 percent improvement in overall fuel economy (even higher in city-only driving) at a cost under $500 per vehicle. Micro-hybrid electric vehicle technology will be deployed as standard equipment in millions of vehicles in Europe, Asia and North America over the next several years.

Although lead-acid batteries can address a portion of the micro-hybrid market, their limited charge acceptance and short service life restrict their effectiveness in a start/stop operation. PowerGenix rechargeable Nickel-Zinc (NiZn) batteries offer micro-hybrids significant performance improvements by overcoming the cycle and calendar life limitations of lead-acid cells. Replacing a lead-acid battery with NiZn results in up to 70 percent reduced battery weight and size, further increasing vehicle fuel efficiency.

In case of mild and full Hybrid Electric Vehicles (HEV), Rechargeable Nickel-Zinc (NiZn) Batteries are a high performance and low-cost alternative to the Nickel-Metal Hydride (NiMH) batteries. With superior energy density and power density compared to NiMH battery, NiZn battery reduces battery weight and size by 30 percent and does so at a 25 percent cost advantage over NiMH. The NiZn battery pack provides more power and equivalent hybrid fuel efficiency in a package one-third lighter than the NiMH battery pack.
