The Navy built rechargeable batteries that won't explode on you
The Navy, the airline industry and Samsung all have a major problem with lithium-ion batteries. Specifically, they tend to catch fire more than most people would like. But that could change soon thanks to a new breakthrough from the US Naval Research Laboratory (NRL) that allows for safe, rechargeable nickel-zinc batteries with a similar performance to Li-ion cells, but without all the flames.
PowerGenix NiZn rechargeable AA batteries: finally, some cells worth buying
It's rare if a month flies by without some random university or DIYer proclaiming that the next major jump in battery technology is just over the horizon, and yet, here we are -- in the year 2009 -- still buying overpriced AA cells from Duracell and Energizer that deplete far too quickly given the technology available. Heck, even those standard rechargeable cells have seen their performance degrade hastily in our experiences, and we've been longing for a rechargeable cell that was actually worth its salt for a long, long time. Frankly, we passed off the PowerGenix NiZn battery as just another slice of vaporware when it was first uncovered in late 2008, but after they went on sale this summer, we decided to really put a set through the paces. Click on to find out how we feel about 'em after months and months of hardcore usage.
