High-safety lithium-ion sulfur battery with sulfurized polyacrylonitrile cathode, prelithiated SiOx/C anode and carbonate-based electrolyte

In this work, a lithium-ion sulfur battery has been constructed by employing the sulfurized polyacrylonitrile ([email protected]PAN) cathode, prelithiated SiOx/C anode and commercial carbonate-based electrolyte. Compared with the traditional lithium-sulfur battery, the replacement of lithium metal with prelithiated SiOx/C anode and the use of commercial carbonate-based electrolyte ensure the high safety of the new battery. Meanwhile, the...
