ABSTRACT
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.
