Abstract:
The main issues of lithium–sulfur (Li–S) batteries, including the insulating properties of electrode materials and the dissolution of lithium polysulfides into electrolytes, hinder their further development. Encapsulating S with a conductive agent is considered as an effective way to address these issues. The electrical conductivity of the electrode is substantially improved by the addition of a conductive agent. Furthermore, the polysulfide dissolution is also effectively suppressed by the physical/chemical confinement of the additives. An exploration of new encapsulation agents for the S cathode–hierarchical porous carbon derived from a peanut hull is reported. Such structures comprise the 3D interconnected network carbon and abundant meso/micropores, which significantly improve the electronic conductivity and effectively suppress the polysulfide dissolution. The high S loading, long lifespan, and great rate capability empower such a strategy to be an effective way to push the Li–S battery to further development.
