“…Data from previous studies are included. [36,39,41,42,46,47] ChemSusChem composites were measured for comparison. In Figure S7, the reduction peaks of MnO/ZnO/C are 1.351 and 1.221 V, higher than that of the raw cathode (1.333 and 1.180 V), ZMO cathode (1.340 and 1.204 V), and MnO/C cathode (1.344 and 1.216 V).…”

“…Clearly, when the rate increases roughly 20-fold to 2.0 A g À 1 , our device still provides a high capacity of approximately 118 mAh g À 1 , which is 52.9 % of the maximum capacity, superior to some of typical Mn-based batteries including Zn//MnO@NGS (ca. 6.9 %), [41] Zn//MnO@NÀ C (26.5 %), [46] Zn//MnO (35.5 %), [39] Zn//N-VO-MnO (26.0 %), [42] Zn// MnO@C (50.0 %) [47] and Zn/MnO@C (35.0 %). [36] Furthermore, our Zn//MnO/ZnO/C device achieves a high capacity of about 155 mAh g À 1 , even at 1.0 A g À 1 (Figure 3f), which exceeds the recent Zn//MnO@NGS (18.9 mAh g À 1 ), [41] Zn//MnO@NÀ C (100.5 mAh g À 1 ), [46] Zn//MnO (95 mAh g À 1 ), [39] Zn//N-VO-MnO (139 mAh g À 1 ), [42] Zn//MnO@C (136 mAh g À 1 ), [47] and Zn//MnO@C (148 mAh g À 1 ) [36] batteries under the same rate.…”

Acidic zinc−carbon dry batteries have been widely used in life because of their low cost. However, a great quantity of used batteries is discarded as refuse, which not only wastes resources but also leads to environmental contamination. To reuse spent batteries on a large scale, this study concerns a simple, effective, and sustainable strategy to turn them into MnO/ZnO/C composites. After a conventional leaching treatment followed by pyrolysis, the rust cathode materials can be reduced to MnO/ZnO/C. When serving as a rechargeable zinc‐ion battery cathode, this electrode provides a maximum reversible capacity of around 362 mAh g−1MnO) and a rate capability of 191 mAh g−1MnO at a high current rate of 1.20 A g−1. Furthermore, ZnO gradually dissolves in the electrolyte with the increase of discharge cycles, replenishing the Zn2+ content in the electrolyte and further enhancing cycling stability (98.02 % after 500 cycles). The device also exhibits a remarkable energy density of 336.37 Wh kg−1, low self‐discharge rate, and can efficiently power a LED panel. This strategy offers an economical and facile route to convert zinc−carbon battery waste into useful materials for aqueous rechargeable zinc ion batteries.
