Lithium‐sulfur batteries with high energy density and low cost have been widely studied, especially, the designing of flexible self‐supporting electrodes. In this paper, the fabrication method and development history of carbon‐based flexible self‐supporting sulfur cathode are detailedly introduced. Meanwhile, carbon substrates with various dimension construction units were classified into different categories to discuss their structure–activity relationship in lithium‐sulfur batteries electrochemical performance enhancement. On the basis of the advantages and shortcomings of different types of cathodes, some expectations and design conceptions are laid out for the lithium‐sulfur batteries with long life, fast redox kinetics, and a wide working temperature range.
