According to a press release, the battery being developed involves a composite cathode of metal fluoride and should be more powerful and compact yet give the packaged batteries specific energies of 400-500 Wh/kg, which is about double that of modern lithium ion polymer cells. The potential impact for hybrid and electric vehicles, as well as for military applications such as UAVs and directed energy weapons, could eventually be enormous. That would turn the 200+ mile range of a Tesla Roadster to (engaging mythical mathematical prowess powers) over 400 miles or a 120 mile Aptera into, well, 240 miles. Now if they could also somehow halve the cost, your grandchildren may one day ask you what gasoline was.
