“…In general, the common methods for the preparation of GICs include chemical oxidation, electrochemical oxidation, the vapor diffusion method, and ultrasonic oxidation [35][36][37][38]. Among these methods, chemical oxidation is the most prevailing, but it consumes many chemical reagents and may cause serious environmental pollution.…”

The robust development of electric vehicles has driven a surging decommission stream of lithium-ion batteries (LIBs) owing to their limited service life. The recycling of spent LIBs has become an urgent and essential task for the sustainable development of the LIB industry. However, the prevailing recycling methods focus only on recycling valuable metal, whilst the graphite anode materials are usually discarded or burned as fuels, leading to great waste of valuable carbon material. A facile strategy to obtain value-added products in an efficient manner is of great significance for the recycling of spent graphite. As graphite has excellent microwave absorption capability and electrical conductivity, microwave radiation on spent graphite can induce a Joule heat–discharge–plasma coupled effect, leading to a rapid heating process, especially when discharge occurs, exhibiting a thermal shock effect with the generation of a large number of high-energy electrons and active materials. This special feature facilitates microwave heating that is tailored for assisting the removal of impurities, structure repair, and graphite intercalation and exfoliation in an efficient manner. Therefore, different from the conventional graphite recycling route that is associated with energy/solution-intensive processes, this paper reviews the progress on microwave-assisted removal of impurities, repair of damaged graphite structure, and innovatively discusses the breakthroughs in microwave-assisted preparation of graphite intercalation compounds, expanded graphite, graphene and graphene-based materials, and porous graphene, with an aim to provide a scientific reference for the value-added resource utilization of spent graphite and preparation of new energy storage materials.

In recent years, graphene‐based nanomaterials have attracted extensive attention because of their excellent physical and chemical properties, such as high strength, high conductivity, high thermal conductivity and excellent lubrication performance. Here, the latest research progresses of graphene‐based nanomaterials are reviewed in this paper, and its synthesis method, unique structure, dispersion improvement strategy and wide application in tribology are emphatically discussed. Graphene‐based materials are synthesized by typical chemical vapor deposition and reduced graphene oxide, showing nanoporous structure characteristics and excellent layered structure. Furthermore, through adjusting the chemical structure for the material, the graphene‐based materials with specific lubricating properties can be designed to meet the use requirements under different working conditions. In view of the easy agglomeration of graphene, physical and chemical dispersion methods, such as in‐situ polymerization and functionalization treatment, were introduced, which significantly improved its dispersibility in the matrix. In tribology, graphene‐based nanocomposites present the excellent anti‐friction and anti‐wear properties, which effectively reduce the coefficient of friction and prolong the service life of materials with forming the stable lubricating films. The summary for graphene‐based materials provides theoretical basis and technical support for applications in high‐end manufacturing, energy storage, and protective coatings.
