Researchers Develop More Efficient 'Lithium-Air' Battery #batterynews

Massachusetts researchers using a fabricated form of carbon have developed battery technology that they hope will enable electric cars to travel far longer distances. Chemists Dunwei Wang of Boston College and Wei Fan of the University of Massachusetts used an engineered form of the element — called 3DOm carbon — to enhance reactions between lithium and oxygen in batteries. Researchers seeking a more efficient battery — one capable of allowing cars to travel hundreds of miles without recharging — have focused on the relationship between lithium and oxygen. They believe such "lithium-air" batteries would resolve size and cost constrains faced by current lithium ion batteries. But the presence of carbon, an essential component in all batteries, previously proved too unstable to generate longer life cycles for the lithium-oxygen reaction. 3DOm carbon, which has a far more ord...
