Revolutionary nanowire battery tech can be charged over 200,000 times

Lithium-ion batteries have enabled a brave new world of powerful wireless devices, but they're not without their limitations. After being charged a number of times, they start to lose their ability to hold that charge, requiring either a replacement battery or a brand new phone. Most batteries last 5,000 to 7,000 recharges, or cycles.
Researchers Reginald Penner and Mya Le Thai of UC Irvine may have created a solution to this dilemma, with a nanowire battery that can be recharged hundreds of thousands of times. According to the pair, nanowires, which increase the surface area of the battery's electrodes, are very fragile and start cracking and degrading after a period of use.
By coating the nanowires in a shell of manganese dioxide and a Plexiglas-like electrolyte gel, Le Tai was able to cycle the an electrode over 200,000 times without detecting any loss of capacity or power, and with no nanowire fractures or degradation.

Manganese is also part of lithium ion battery chemistries that are resistant to ignition or explosions when packaging ruptures and is exposed to atmosphere.

Sounds like a win-win battery design to me. Nanowires are still a bit pricey to mass produce, but that may change. The green / renewable energy landscape just improved.

Hey! that is almost as good as the Edison Battery! Too bad it is tiny, lab scale experiment. (Photo at Plaxma's link looks AAA size.)

This one lasted more than 30 years with more than one daily deep discharge cycle. (It may still be going strong - there is no evidence of capacity loss, even in projectons of 100 years of deep discharge use.) You need 10 cells in series to get 12Volts. Iron & nickle and the electrolyte are cheap and so environmentally sound, you can just dump them in the trash, if and when, they ever do finally fail.

Here is modern one you can buy today:

Unless you are a sub-teenager, you will be dead before it is. US now has two active makers and China makes them too. Specifications from: http://www.nickel-iron-battery.com/

Energy/weigh: 30-50Wh/kg
Energy/size: 30 Wh/l
Power/weight: 100W/kg
Charge/discharge efficiency: 65% - 85%
Energy/consumer-price: 1.5 – 6.6Wh/US$
Self-discharge rate: 10-15% /month
Time durability: 30– 100 years
Cycle durability: Repeated deep discharge does not reduce life significantly.

They are ideal with solar or wind as mean to provide continueous DC power (Best form for wind machine as easy and efficient to get 60Hz.) Due to difusion solar cells will fail before the Edision Battery does!
