This disposable aqueous primary battery chemistry utilizes environmentally benign sulfur cathode and Zn anode, showcasing high energy density and areal capacity under high mass loading conditions.
We demonstrate a disposable aqueous primary battery chemistry that comprises environmentally benign materials of the sulfur cathode and Zn anode in a 1 M ZnCl2 aqueous electrolyte. The Zn-S battery shows a high energy density of 1083.3 Wh kg(-1) for sulphur with a flat discharge voltage plateau around 0.7 V. When operating at a high mass loading of 8.3 mg cm(-2) for sulfur in the cathode, the battery exhibits a very high areal capacity of 11.4 mA h cm(-2) and areal energy of 7.7 mW h cm(-2).
