Why Chinese space station is studying how gravity affects battery performance

Led by only the second civilian the country has sent into space, China had started a series of experiments on board its Tiangong space station that could lead to the development of safer and more powerful space batteries, state media reported on Wednesday. The tests on lithium-ion batteries run by Zhang Hongzhang, a professor at the Dalian Institute of Chemical Physics, could help scientists better understand how gravity affects the workings of the batteries. Zhang, 39, is one of the three...
