Photoassisted lithium–sulfur battery (PALSB) can promote the solar energy application. A freestanding Au@N-TiO 2 /carbon cloths (CC) photoelectrode for PALSB cannot only work as a photocatalyst that produces the electrons and holes to facilitate the reduction and evolution of sulfur, but also can work as an electrocatalyst to promote the conversion of intermediate polysulfides during charge/discharge process. Abstract Integration of solar cell and secondary battery cannot only promote solar energy application but also improve the electrochemical performance of battery. Lithium–sulfur battery (LSB) is an ideal candidate for photoassisted batteries owing to its high theoretical capacity. Unfortunately, the researches related the combination of solar energy and LSB are relatively lacking. Herein, a freestanding photoelectrode is developed for photoassisted lithium–sulfur battery (PALSB) by constructing a heterogeneous structured Au@N-TiO 2 on carbon cloths (Au@N-TiO 2 /CC), which combines multiple advantages. The Au@N-TiO 2 /CC photoelectrode can produce the photoelectrons to facilitate sulfur reduction during discharge process, while generating holes to accelerate sulfur evolution during charge process, improving the kinetics of electrochemical reactions. Meanwhile, Au@N–TiO 2 /CC can work as an electrocatalyst to promote the conversion of intermediate polysulfides during charge/discharge process, mitigating induced side reactions. Benefiting from the synergistic effect of electrocatalysis and photocatalysis, PALSB assembled with an Au@N-TiO 2 /CC photoelectrode obtains ultrahigh specific capacity, excellent rate performance, and outstanding cycling performance. What is more, the Au@N-TiO 2 /CC assembled PALSB can be directly charged under light illumination. This work not only expands the application of solar energy but also provides a new insight to develop advanced LSBs.
