Recently, the Li-S primary battery with energy density of 500 Wh/kg (650 Wh/L) has been achieved in Prof. Huamin ZHANG and Prof. Hongzhang ZHANG’s group, due to the successful R&D of novel sulfur hosts. The sulfur hosts were designed as hierarchical orderly porous carbon materials with large pore volume, high specific surface area. This research work was published on the “Scientific Report 2015, 5, 14949” and named as “Lithium Sulfur Primary Battery with Super High Energy Density: d on the Cauliflower-like Structured C/S Cathode”.

With further breakthrough in the Key materials, the energy density of Li-S primary battery has achieved 860 Wh/kg (1000 Wh/L), with good shelf stability and discharge stability at room temperature. The as developed Li-S primary battery shows promising for commercial application.
