Engineers at the University of California San Diego have developed lithium-ion batteries that perform well at freezing cold and scorching hot temperatures, while packing a lot of energy. The researchers accomplished this feat by developing an electrolyte that is not only versatile and robust throughout a wide temperature range, but also compatible with a high energy anode and cathode.

The temperature-resilient batteries are described in a paper published the week of July 4 in Proceedings of the National Academy of Sciences (PNAS).
Such batteries could allow electric vehicles in cold climates to travel farther on a single …
