Chemistry Found For Not Burn Not Explode Lithium Batteries
September 12, 2017 | 4 Comments
Researchers at the University of Maryland and the U.S. Army Research Laboratory have developed a lithium-ion battery that uses a water-salt solution as its electrolyte. The chemistry solution also reaches the 4.0 volt mark desired for household electronics, such as laptop computers, without the fire and explosive risks associated with some commercially available non-aqueous lithium-ion […]

Current Lithium Batteries Could Be 3 Times Better
July 6, 2016 | 2 Comments
Paul Scherrer Institut materials researchers have developed a very simple and cost-effective procedure for significantly enhancing the performance of conventional lithium-ion rechargeable batteries by up to 300%. They said the procedure is scalable in size, so the use of rechargeable batteries would be optimized in all areas of application – whether in wristwatches, smartphones, laptops […]

Lithium & Sodium Batteries Improved with Graphene Oxide
December 30, 2014 | Leave a Comment
A Kansas State University (KSU) engineering team has discovered some of graphene oxide’s important properties that can improve sodium and lithium-ion flexible batteries. The KSU team is the first to show that a flexible paper composed entirely of graphene oxide sheets can charge and discharge with sodium-ions for more than 1,000 cycles. Sodium perchlorate salt […]

The Best Lithium Air Batteries Get a 33% Boost
February 8, 2012 | Leave a Comment
The best lithium air lab research batteries had cathodes built with graphene nanosheet materials. Back in August of 2011 scientists at the Nanomaterials and Energy Group at the University of Western Ontario (UWO), Canada, reported the development of graphene nanosheet cathode (GNS) materials for non-aqueous lithium-oxygen (Li-air) batteries showing a capacity of 8,705.9 mAh g-1 […]
