I was forwarded an article about battery tech from globalspec. Of course, I don't know how soon they are to selling these things commercially, or the price. A 20 year shelf life for a fuel cell battery charger sounds pretty sweet. view.email.globalspec.com/?j=fe5a1675766d007a7117&m=fef11d73726d06&ls=fdf715747764017c7c137771&l=fefb107070670c&s=fe2e10727564027c711379&jb=ff941374&ju=fe1616747c6c0c757c1273&r=0Some Flexibility with Electrode Material Choice Flexible electronics integrated into consumer products and wearable devices require a flexible power source. The use of bendable lithium-ion batteries for such applications has been hindered by electrode material limitations — until now. Fabrication using a two-step deposition/transfer process allows any material to serve as the electrode. Encased between polymer sheets, this thin-film battery has exhibited a 106 μAh/cm² charging capacity and 4.2 V charging voltage. Watch the bendable battery with lithium cobalt oxide cathode power a flexible organic LED. Portable Charging Cell phones and other portable electronics are recharged with a compact, disposable hydrogen fuel cell from Japan. Thin sheets of solidified calcium hydride produce 4.5 L of hydrogen and 5 Whr power output at ambient temperature. Long-term energy storage is another plus claimed for the soon-to-be-commercialized packets: the shelf-life is 20 years as long as the device remains sealed.
