摘要

在1 M Mn 2 +溶液中对再生电池石墨进行原位电化学剥离，生成了富含碳氧官能团的缺陷氧化石墨烯，并均匀沉积了δ- mno2，在超级电容器（v=1 mV s-1时CV为1126 F -1）和水锌离子电池（0.4 A g⁻¹时CV为35 mA h -1）中表现出优异的性能。

Sustainable Fabrication of δ-MnO₂/Graphene Oxide Composites from Waste Battery Graphite via In-Situ Electrochemical Exfoliation for Supercapacitors and Aqueous Zinc-Ion Batteries

In situ electrochemical exfoliation of recycled battery graphite in 1 M Mn²⁺ solution produced defective graphene oxide enriched with carbon-oxygen functional groups and uniformly deposited δ-MnO₂, demonstrating excellent performance in supercapacitors (1126 F g-1 by CV at v=1 mV s-1) and aqueous zinc-ion batteries (35 mA h g⁻¹ at 0.4 A g⁻¹)
