Range anxiety, the fear that such vehicles will leave the vehicle's occupants stranded well short of their destination, remains one of, if not the main barrier to the widespread adoption of EVs. A new material developed by Japanese company Sumitomo Electric could help allay such fears by potentially improving the capacity of lithium-ion batteries by 1.5 to three times, and therefore extending the range of EVs by by an extra 50 to 200 percent. That would give a Nissan LEAF a range of up to 109 to 219 miles (175 to 352 km) or a Tesla Roadster a range of up to 366 to 732 miles (589 to 1,178 km) - enough to assuage the range anxiety of the most fretful drivers.
