The sustainable fabrication of δ-MnO <sub>2</sub> /graphene oxide composites from waste battery graphite <i>via in situ</i> electrochemical exfoliation for supercapacitors and aqueous zinc-ion batteries
The <i>in situ</i> electrochemical exfoliation of recycled battery graphite in 1 M Mn<sup>2+</sup> solution produced defective graphene oxide enriched with carbon-oxygen functional groups and uniformly deposited δ-MnO<sub>2</sub>, demonstrating excellent performance in supercapacitors (1126 F g<sup>-1</sup> based on CV at <i>v</i> = 1 mV s<sup>-1</sup>) and aqueous zinc-ion batteries (35 mA h g<sup>-1</sup> at 0.4 A g<sup>-1</sup>).
