Chinese researchers achieve 700 Wh/kg lithium battery using fluorinated hydrocarbon electrolyte

Co-developer of the electrolyte; potential near-term customer for space applications

The best commercial lithium batteries today store about 250 to 300 watt-hours per kilogram. A team from Nankai University and the Shanghai Academy of Spaceflight Technology — which builds China's rockets and space station modules — has published results in Nature. The new fluorinated hydrocarbon electrolyte pushes lithium metal batteries to 700 Wh/kg at room temperature and nearly 400 Wh/kg at minus 50 degrees Celsius.
