The Dalian Institute of Chemical Industry of the Chinese Academy of Sciences broke through the technical bottleneck of lithium-sulfur primary batteries

Recently, the research team of Zhang Huamin and Zhang Hongzhang of the Energy Storage Technology Research Department of Dalian Institute of Chemicals, Chinese Academy of Sciences, successfully developed a carbon-sulfur composite cathode
based on large-pore volume, high-specific surface, gradient-ordered porous carbon materials.
At the same time, the energy density of the lithium-sulfur primary battery developed by it exceeds 500 Wh/kg
.

At present, the team has broken through the technical bottleneck of key materials for lithium-sulfur primary batteries, and the energy density of the battery has been increased to 860 Wh/kg
.
At the same time, its shelving stability is good, it can operate smoothly at room temperature, can meet the needs of aerospace, marine exploration, reserve power supply, large-scale energy storage and other fields, and has good industrialization development prospects
.
