Zhang Hua-min and Zhang Hong-chang, a research team of the Institute of Energy Storage Technology, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, successfully developed a carbon-sulfur composite positive electrode based on large pore volume, high specific surface and gradient ordered porous carbon materials. At the same time, using its developed lithium-sulfur primary battery energy density over 500 watts / kg (650 watt hours / liter). Related results recently published in the "scientific report" magazine.
Currently, the team has broken the technical bottleneck of key materials for lithium-sulfur primary batteries and has raised battery energy density to 860 watt hours / kilogram (1000 watt hours / liter). At the same time, it has good shelving stability and can run smoothly at room temperature. It can meet the needs of aerospace, marine exploration, reserve power supply and large-scale energy storage. It has good prospect of industrialization development.
