PowerGenix has been working to improve batteries for two of the world's most common power needs: home based applications (i.e., games, digital cameras, and other high drain devices) and personal transportation uses like the automobile. Previously, most consumers looked to alkaline batteries for all high drain devices, especially those that were meant to be used constantly for a set period of time like a hand held game. Alkaline batteries offer the voltage that these devices need, but are generally not rechargeable making them ultimately more expensive. It is also a fact that alkaline batteries are not eco-friendly.
Rechargeable batteries, like the nickel-metal hydride battery and the nickel-cadmium battery, generally do not put out enough power to work consistently or well in the high drain devices that sorely need them. Rechargeable batteries also hold the key to sustainable and lasting clean energy. Nickel-zinc (NiZn) batteries have the technology to deliver not only the recycling ability of other nickel-based battery types, but they also deliver a full 1.5 volts of power. Why then, if this powerful yet recyclable battery is available is it not more commonly used? The answer is quite simple: marketing, availability, and durability.
PowerGenix produces NiZn batteries. These batteries hit the market in December 2008. The batteries themselves are labeled as the "Quantaray Super Z" rechargeable AA battery (Practical Environmentalist 2008). Durability is the problem with these batteries because the zinc electrodes do not last as long as other materials. NiZn batteries do offer higher energy density, however, so the trade off might be worthwhile for some consumers.
Consumer-based high-drain devices such as hand-held games have a voracious need for batteries. If a hand-held game drains its alkaline (non-rechargeable) batteries after four hours of use per day, and the game is played a minimum of four days each week, the total battery usage would be 64 for the week. At the minimum, a four pack of AA batteries costs $1.00. At this price, the cost or operating a single hand-held game will be $64 per week, $256 per month, and $3072 per year.
PowerGenix is also working on NiZn batteries for electric and hybrid cars. It will take time for these batteries to catch up to and overtake the more common lithium-ion batteries, especially in this application, but it is only a matter of time. NiZn batteries are reportedly cleaner to produce and are also supposed to be the easiest to recycle meaning double benefits for the environment.
