Rechargeable batteries perform poorly when it’s cold out. Now researchers have designed a new lithium-ion battery that still works at –70 °C. Such batteries could improve the performance of electric cars in winter, and help power high-altitude machinery, space stations, and planetary rovers (Joule 2018, DOI: 10.1016/j.joule.2018.01.017).

On cold winter days, electric vehicles can lose half their driving range due to poor battery performance. At –40 °C, lithium-ion . . .
