A nanoporous sulfur-bridged hexaazatrinaphthylene framework as an organic cathode for lithium ion batteries with well-balanced electrochemical performance.

Some inherent drawbacks of organic cathode materials include low conductivity and high solubility in electrolytes, which lead to low rate capability and low cycling stability. Herein, a novel nanoporous sulfur-bridged hexaazatrinaphthylene (NSHATN) framework has been developed. The sulfur-bridged aromatic framework has good electrical conductivity and is insoluble in electrolytes.
