With all the chaos surrounding lithium-ion batteries recently, the timing of this announcement seems eerily prescient: A company called Zinc Matrix Power is close to releasing a rechargeable battery made of silver and zinc.
The batteries have absolutely no lithium and certainly no flammable liquids; in fact, the silver-zinc batteries are created using a water-based chemistry. This makes for virtually no fire risk and also makes the batteries easier to recycle (since they won’t be leaking any of those harmful chemicals). In addition, the company claims that they have twice the runtime of their lithium-ion counterparts.
Look for those batteries to appear in a big way this fall, and look to be able to use them in both notebooks and mobile phones.
