Hybridized S cathode with N719 dye for a photo-assisted charging Li-S battery

An integrated battery system, which integrates solar power and rechargeable battery in the same unit, is recognized as a propective solution for the shortage and inefficiency of power energy. Herein, a hybrid S/N719 dye cathode is proposed in the rechargeable Li-S battery to realize the photo-assisted charging battery system. Specifically, the photo-charge contribution reduces the charge voltage of the sulfur cathode by 0.12 V and accelerates the charge process under light illumination, showing the great potential in saving electric energy and expediting fast-charge capacity of Li-S battery.
