Abstract:
A self-inhibiting, gradient sulfur structure was designed and developed by the synthesis of a carbon nanofiber-sulphur composite via sulfur vapor deposition method for use as a binder-free sulfur cathode, exhibiting high sulfur loading (2.6 mg cm(-2)) and high sulfur content (65%) with a stable capacity of >700 mA h g(-1).
