Silicon–air batteries are a new battery technology invented by a team led by Prof. Ein-Eli at the Grand Technion Energy Program at the Technion – Israel Institute of Technology. Silicon–air batteries are created from oxygen and silicon. Such batteries would be lightweight, and have a high tolerance for both extremely dry conditions and high humidity and would provide significant savings in cost and weight because the built-in cathode of conventional batteries is not present in silicon–air batteries.〔(Silicon–Air Battery: Non-stop Power for Thousands of Hours )〕〔(New Silicon-Air Battery to Have Unlimited Shelf Life )〕 The experimental cells described in the journal ''Electrochemistry Communications'' using a room-temperature ionic liquid as electrolyte produced between 1 and 1.2 volts at a current density of 0.3 millamperes per square centimeter of silicon.〔http://www.sciencedirect.com/science/article/pii/S1388248109003889 Abstract of paper ''Silicon–air batteries'' , Volume 11, Issue 10, October 2009, Pages 1916-1918 in ''Electrochemistry Communications'', retrieved 2011 Aug 3〕 == History == The only research report available to the public was done by its creator Professor Yair-Ein-Eli. Eli began research in Technion - Israel Institute of Technology with Dr. David Starosvetsky, graduate student Gil Cohen of Technion, Professor Digby Macdonald of Pennsylvania State University, and Professor Rika Hagiwara of Kyoto University. Eli's reasoning for using silicon as a fuel cell is because of its high specific energy, availability as a resource(eighth most plentiful in the universe, second most plentiful in Earth's crust), tolerance of places with high humidity, and non-toxic properties. In their experiments, they tested for different potential energies and voltages using different liquid oxygen solutions. The experimental results and theories on the battery were published online in 2009 in the journal ''Electrochemistry Communications''. This got the attention of organizations such as DARPA and the Pentagon where they are currently working on military usage of this battery. The battery is still under research by these organizations and not available for commercial use. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Silicon–air battery」の詳細全文を読む スポンサード リンク
