Mechanochemical Upcycling of Spent Battery Graphite into a Self-Cleaning Adsorbent for Wastewater Treatments.

ABSTRACT: The cost-effective upcycling method of waste anode graphite (SG) presents an important challenge within the field of spent lithium-ion battery recycling. In this study, waste graphite was recovered from waste lithium-ion batteries by a one-step mechanochemical method and the high-efficiency graphene-based adsorbent OMG17 was synthesized. Following this, titanium dioxide microspheres (TiO₂) were integrated through electrostatic self-assembly to create an in situ photo-regeneration adsorbent, referred to as OMG17@TiO₂. The synthesized OMG17@TiO₂ exhibits a well-developed pore structure, characterized by regular crack-like pores and an abundance of functional groups. Furthermore, OMG17@TiO₂ was fabricated into a membrane via the vacuum filtration me
