Facile recyclable process of high-quality single layer graphene oxide via waste graphite anode scrap

Direct regeneration of spent graphite anode material via a simple thermal treatment method

“…15 Currently, the traditional recycling directions can be roughly categorized into three approaches: (i) pyrometallurgical, 16,17 (ii) hydrometallurgical, 18–20 and (iii) transformation to other materials. 21–23 Pyrometallurgical recycling involves baking spent graphite at temperatures over 1000 °C to decompose impurities through high calcine and restore the graphite structure, achieving recovery. 24 Gao et al showed excellent physical properties close to those of commercial graphite using 900 °C heat treatment of graphite.…”
