Nickel oxyhydroxide battery (AA/AAA, 1.7V) - space-time - 04-24-2016 have you ever used one? they were introduced by Panasonic in 2005 (2004 in Japan). They put out 1.7 V, have higher capacity than Alkaline batteries, but were discontinued in 2011. I never know these existed until today, when I was doing some research to see which batteries are less likely to leak in devices I don't use often (spare remote controllers and such). Here are some interesting links for your reading pleasure DAVID POGUE, NYT: Can a New Disposable Battery Change Your Life? Parts of It, Maybe Michael Bluejay's Battery Guide Wikipedia: Nickel oxyhydroxide battery I really wish these were still being made today. Re: Nickel oxyhydroxide battery (AA/AAA, 1.7V) - The Grim Ninja - 04-24-2016 I'd like to see Lithium Ion 18650 and smaller variants become more popular. I've been playing with them in flashlights and my other electronic hackery, they're rather awesome. A single 18650 can replace two AA's and holds more power, plus rechargeable. The charger circuitry is extremely cheap now, too. Re: Nickel oxyhydroxide battery (AA/AAA, 1.7V) - SDGuy - 04-24-2016 I hope this pans out soon... "Instead of lithium, researchers at UC Irvine have used gold nanowires to store electricity, and have found that their system is able to far outlast traditional lithium battery construction. The Irvine team's system cycled through 200,000 recharges without significant corrosion or decline. However, they don't exactly know why. The original idea of the experiment was to make a solid-state battery: one that uses an electrolyte gel, rather than liquid, to help hold charge. Liquid batteries, like the common lithium variety, are extremely combustible and sensitive to temperature. The Irvine team was experimenting by substituting a much thicker gel. "We started to cycle the devices, and then realized that they weren't going to die," said Reginald Penner, a lead author of the paper. "We don't understand the mechanism of that yet."" Re: Nickel oxyhydroxide battery (AA/AAA, 1.7V) - Bill in NC - 04-24-2016 the higher voltage can damage some electronics. IIRC, users over at candlepowerforums reported that they would sometimes leak under heavy load. |
