Major breakthrough in lithium battery technology reported

Canadian researchers have demonstrated the first robust lithium-sulphur battery, as well as a new approach to creating composite materials. Lithium-sulphur batteries have been long been sought because they have potential for high energy densities and sulphur is cheaper to obtain than materials currently used in lithium-based batteries. The team developed a nano-casting technique consisting of a structure of nanoscale carbon rods seperated by empty channels. The rods kept the channels open until molten sulphur was added. Capillary forces drew the sulphur into the channels where it solidified into sulpher nanofibers. The resulting battery demonstrated 3 times the storage capacity of lithium-ion batteries. The researchers are currently ironing out the details with an eye to commercialization.
