Rechargeable lithium-sulfur batteries are potentially high-energy- density and low-cost electrochemical devices for future electric transportation and stationary energy storage, however the short cycle life imposes a strong constraint on their applications. On the cathode side, poor cycling stability is mainly caused by uncontrolled diffusion of lithium polysulfide intermediates. Our research aims to address this key challenge by realizing rational design of high-performance sulfur cathodes based on molecular level understanding of the chemical interactions at material/polysulfide interfaces.
