The First Pure Lithium Battery Claim Is Made
July 30, 2014 | 1 Comment
Stanford researchers report that they have taken a big step toward designing a pure lithium anode – an accomplishment that battery designers have been trying to do for decades. The group’s paper has been published in the journal Nature Nanotechnology. Chemical batteries have three basic components: an electrolyte to provide electrons, an anode to discharge […]

Lithium Battery Material Redesign For a Big Improvement
February 6, 2013 | Leave a Comment
SLAC National Accelerator Laboratory and Stanford University scientists set a new world record for energy storage, using a clever “egg yolk-shell” design to store five times more energy in the sulfur cathode of a rechargeable lithium-ion battery. The comparison is made directly to today’s commercial technology. The performance is quite impressive beyond the capacity. The […]

Halfway to the Ultimate Lithium Battery
November 16, 2011 | 1 Comment
Northwestern University engineers show in the journal Advanced Energy Materials they have developed technology that could hugely improve lithium batteries. The new anode technology suggests a cellphone battery might recharge in 15 minutes and last ten times longer. The scientists combined two chemical engineering approaches to address two major battery limitations — energy capacity and […]
