Researchers announce significant improvement in Li-S battery performance and cycle life

A team from the University of Waterloo in Canada and BASF has developed a way to stabilize cathodes in lithium-sulfur batteries, significantly improving performance and cycle life. Li-S batteries offer high theoretical energy density and low cost, due to the high natural abundance of sulfur. However, the insulating nature of sulfur and lithium sulfides requires… Read more »

PG&E and BMW team up to test V2G services

Pacific Gas and Electric Company (PG&E) and BMW are working together to test the ability of EV batteries to provide services to the electrical grid. PG&E selected BMW after a competitive solicitation to manage a minimum of 100 kilowatts of electric demand on PG&E’s system, as other large industrial and commercial customers do today as… Read more »

Graphene wrapper enhances performance of lithium-sulfur batteries

Lithium-sulfur batteries are of great interest, as they could offer specific energy densities far greater than those of current lithium-ion chemistries. However, current designs are plagued by low efficiency and capacity degradation. A team of researchers from the University of Cambridge and the Beijing Institute of Technology has devised a three-dimensional sandwich-type graphene sheet-sulfur/carbon composite… Read more »

Research team uses MRI to examine the inner workings of supercapacitors

A team of chemists from New York University and the University of Cambridge has developed a method for examining the inner workings of supercapacitors. Their technique, based on magnetic resonance imaging (MRI), offers a way to monitor and possibly enhance the performance of such devices. The work, which appears in the latest issue of the… Read more »

South Korean team develops coated LMO cathode that lasts longer at high temperatures

The quest for the better battery involves ongoing research on improving and optimizing materials used for lithium-ion cells. One such material is LiMn2O4 (LMO), which offers high power and low cost, but cell life at high temperatures can be problematic. In a paper in Nano Letters, a team from the Ulsan National Institute of Science… Read more »

Virgin and Venturi racing teams round out Formula E roster

Two high-profile groups have announced plans to field teams for Formula E, the all-electric racing series that will take place in 10 city centers around the world, beginning in Beijing in September 2014. The Virgin Racing and Venturi teams became the ninth and tenth to join, making the roster complete. Sir Richard Branson’s Virgin empire… Read more »

MIT team uses virus to make a better lithium-oxygen battery

Researchers around the world have taken up the quest for a better battery, and lithium-air is one of the many promising routes to the Grail. This week, a team from MIT described an improved way to make nanowires for a lithium-air battery electrode using – of all things – viruses. “Biologically enhanced cathode design for… Read more »

Prologis to build two electric truck charging hubs in Southern California

Logistics real estate specialist Prologis has unveiled two upcoming electric truck charging installations as part of its Prologis Mobility platform. The two charging sites will enable Performance Team, a national logistics company, to simultaneously charge up to 38 of its Volvo VNR Electric Class 8 battery-electric trucks. Prologis manages some 1.2 billion square feet of… Read more »
