Abstract At present, electronic devices such as electric vehicles and mobile phones have increasing requirements for battery energy density. Lithium–sulfur batteries (LSBs) a high theoretical density are considered potential choice realizing the next generation of (2600 W h kg −1 ) batteries. However, actual LSBs is much lower than due to poor conductivity sulfur, serious LiPSs shuttle, low sulfur utilization, so on. Many lightweight materials characterized by surface area designability. The reasonable design modify can reduce proportion inactive substances optimizing electrochemical performance, which crucial improving LSBs. few reviews discuss effect on from perspective whole system. Herein, application in six aspects: liquid electrolyte, solid cathode, anode, separator, current collector discussed. significance use further improvement summarized prospected.
