Recently, the research team of Zhang Huamin and Zhang Hongzhang of the Department of Energy Storage Technology of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences successfully developed a carbon-sulfur composite positive electrode based on a large pore volume, high specific surface, and gradient-order porous carbon material. The primary battery energy density reaches 500Wh/kg (650Wh/L) or more. Related Research Results Lithium Sulfur Primary Battery with Super High Energy Density: Based on the Cauliflower-like Structured C/S Cathode Online published in Scientific Report (2015, 5, 14949).
The research group broke through the technical bottleneck of lithium sulfur primary battery key materials, the battery energy density has been increased to 860Wh/kg (1000Wh/L) or more, shelved stability is good, stable operation at room temperature, has a good prospect of industrial development. At the same time, the research team has devoted many years to the research and development of key materials for lithium-based batteries, and has also conducted a large number of basic research work on new carbon materials, sulfur-based composite materials, electrode structures, separators, binders, and electrolyte materials. The research papers published in 2015 have included: J. Mater. Chem. A, 2015, 3, 19469-19475; J. Mater. Chem. A 2015, 3, 15314-15323; ACS Appl. Mater.
