Popular Science’s DIY Gravity Battery. Yields 1volt, no mention of cycle life.
Having moved way beyond sloshing glasses of batteries, A123 has secured another 40 Million of investments for their high-powered lithium battery development. “A123Systems has quickly become one of the World’s largest suppliers of high-power lithium-ion batteries. Based on the Company’s patented nanophosphate technology, the batteries deliver previously unattainable levels of power, safety and life.”
The folks over at the US Dept of Energy Lawrence Berkeley National Laboratory have been working on improved fuel cell cathode catalysts. “The next step”, Stamenkovic said, “will be to engineer nanoparticle catalysts with electronic and morphological properties that mimic the surfaces of pure single crystals of Pt3Ni.”
