A lithium battery that operates at -70 degrees Celsius, a record low

Researchers in China have developed a battery with organic compound electrodes that can function at -70 degrees Celsius — far colder than the temperature at which lithium-ion batteries lose most of their ability to conduct and store energy. The findings could aid engineers in developing technology suited to withstand the coldest reaches of outer space or the most frigid regions on Earth.
