Lots of efforts have been done on different porous carbon materials as cathode for Lithium–
sulfur (Li–S) battery. However, seldom researches have been done on the relationship
between cathode thickness and electrochemical performance. Our work investigates the
relation between electrochemical performance and cathode thickness with typical porous
carbon materials. We explain the phenomenon that only a modest cathode thickness can
have the most adequate electrochemical reaction trend through the aspect of …
