Researchers develop new lithium-ion batteries that perform well in both heat and cold
Researchers have developed new lithium-ion batteries that perform well at both freezing cold and scorching hot temperatures, while packing a lot of energy. The batteries, described in the journal PNAS, could allow electric vehicles in cold climates to travel farther on a single charge. They could also reduce the need for cooling systems to keep the vehicles' battery packs from overheating in hot climates. The researchers at the University of California (UC) San Diego in the US developed an electrolyte that is not only…
