Wilcke, senior, Manager of Nanoscale Science and Technology at IBM\u2019s Almaden Research Center, initiated and heads up the Battery 500 project, a coalition to create a battery that will give electric cars a 500-mile range.\u00a0 Partners include the United States Department of Energy National Laboratories, the<a href=\"http:\/\/www.slac.stanford.edu\/\"> Stanford Linear Accelerator National Laboratory<\/a>, and Stanford University.\u00a0 <a href=\"http:\/\/www.asahi-kasei.co.jp\/asahi\/en\/\">Asahi Kasei<\/a> and<a href=\"http:\/\/www.cgc-jp.com\/ir\/data\/20120420.pdf\"> Central Glass<\/a> have recently joined the enterprise, chosen for their expertise in battery separator membranes and electrolytes respectively.\u00a0 The Project\u2019s goal is to eliminate range anxiety for EV owners and use the excess capacity of the electrical grid at night for charging.<\/p>\n<p>http:\/\/www.youtube.com\/watch?v=ZmHZhBqI500&#038;feature=results_main&#038;playnext=1&#038;list=PLC380E428DEE6351B<\/p>\n<p>Dr. Wilcke explained that if all U. S. drivers had battery-powered electric cars, 73 percent of those EVs could be recharged at night with excess electricity from the grid.\u00a0 Given a typical week for a 500-mile car, a 4 kilowatt home charger used 5 nights out of that week would keep the car on the road with no need for public charging stations or unnecessary stops.<\/p>\n<p>Because Lithium-air cells literally pull their reagent, or reactive element, out of the air, such batteries can achieve up to 1000 Watt-hours per kilogram while weighing considerably less than their solid electrode cousins. \u00a0Current Lithium-ion cells achieve 100-200 wh\/kg, according to Dr. Wilcke, limiting their range partly because of weight considerations.<\/p>\n<p><iframe loading=\"lazy\" title=\"IBM Battery 500\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/RAvcb_E5ZHk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>It\u2019s important that these batteries are rechargeable, because most metal-air batteries are primary, or non-rechargeable cells, and would not readily lend themselves to disposal at the end of trip. \u00a0\u00a0Equivalent lead-acid batteries would weigh 15,900 grams (15 pounds), Lithium-ion 2,200 grams (4.84 pounds) and Lithium-air 300 grams (0.66 pounds) for the same range. Electrolyte choice is critical, since two different electrolytes help the battery achieve its high range, and both need to be capable of surviving multiple charge\/discharge cycles.<\/p>\n<p>Argonne National Labs\u2019 petaflop IBM Blue Gene supercomputer helped model the interactions of all the components of the battery.<\/p>\n<p>In a final illustration of fossil fuel to electric energy densities, Dr. Wilcke explained that filling up his Beech King Air required 384 gallons of Jet A, weighing 2,575 pounds and costing $2,112.\u00a0 Even an equivalent pack of 1,200 wh\/kg batteries would weigh 6,233 pounds.\u00a0 Dr. Wilcke pronounced, \u201cNo joy\u201d for that scenario, just a reflection of how far we have to go to achieve practical electric aviation.<\/p>\n<p>&nbsp;<\/p>\n<div id=\"facebook_like\"><iframe src=\"http:\/\/www.facebook.com\/plugins\/like.php?href=http%3A%2F%2Fcafe.foundation%2Fblog%2Fibm%25e2%2580%2599s-battery-500-project%2F&amp;layout=standard&amp;show_faces=true&amp;width=500&amp;action=like&amp;font=segoe+ui&amp;colorscheme=light&amp;height=80\" scrolling=\"no\" frameborder=\"0\" style=\"border:none; overflow:hidden; width:500px; height:80px;\" allowTransparency=\"true\"><\/iframe><\/div>","protected":false},"excerpt":{"rendered":"<p>One of several presenters at this year\u2019s sixth annual Electric Aircraft Symposium held by the CAFE Foundation at Santa Rosa, California on April 27 and 28 this year, Dr. Winfried W.
