Abstract:

 With the development of emerging flexible electronic devices, high performance flexible power sources have attracted great attention. Lithium sulfur battery with merits in high energy density and low cost holds promise in application in next generation flexible energy battery system. Flexible electrodes are key components in flexible batteries, which serve as electronic conductive skeleton, ion conduction skeleton, and active material hosts. In this paper, the characteristics of lithium-sulfur battery and its flexible cathode are briefly introduced, and the research progress of flexible cathode material for lithium-sulfur battery is reviewed. The future research direction and development space of lithium-sulfur battery are prospected.

Key words: lithium-sulfur battery, flexible cathode, current collector, energy density
