“…As a comparison, the composite treated without plasma can only deliver an initial capacity of 867 mAh g −1 and a reversible capacity of 194 mAh g −1 after 50 cycles. Beside the abovementioned Sn and Si, this group has also applied the plasma milling process to prepare Ge, Fe 2 O 3 , V 2 O 5 , Sn@SnO x , and Sn–Fe 3 O 4 based carbonaceous nanocomposites and achieved better LIB performance.…”

Renewable energy sources such as solar, wind, and hydro hold the promise to meet the huge energy demands of the future at no environmental cost. Harvesting and utilization of these energies require efficient and low cost energy conversion and storage devices, whose performance essentially depends on the properties of the electrode materials. The properties of materials are greatly affected by synthesis methods and can be tuned by chemical modifications. Many approaches have therefore been developed toward this end. Among them, plasma has attracted increasing attention because of its great efficacy in producing and modifying materials under mild conditions. Herein, recent developments in plasma‐assisted synthesis (e.g., plasma conversion, milling, deposition, and exfoliation) and plasma‐assisted modification (e.g., plasma etching, doping, and other surface treatments) of energy conversion and storage materials are highlighted. Challenges and future opportunities in this field are also discussed. This review aims to provide a better understanding of how plasma can be utilized to synthesize and modify a variety of materials including transition metal phosphides, nitrides, chalcogenides, oxides as well as carbon materials, and to promote their additional applications in energy conversion and storage.

In situ synthesis method was used to prepare V 8 C 7 -Cr 3 C 2 nanocomposite. Ammonium vanadate, ammonium dichromate and nanometer carbon black were used as raw materials. The products were characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric and differential scanning calorimetry (TG-DSC) and X-ray photoelectron spectroscopy (XPS) techniques. The results show that V 8 C 7 -Cr 3 C 2 nanocomposite with an average crystallite size of 25.4 nm can be synthesized at 1200°C for 1 h. The synthesis temperature required by the method is at least 200°C lower than that required by the conventional approaches for preparing vanadium and chromium carbides. The powders show good dispersion and are mainly composed of spherical or nearly spherical particles with a mean diameter of about 30 nm. The weight loss ratio of the precursor throughout the reaction process reaches 58 wt%. Three exothermic peaks and four endothermic peaks occur during the reaction. The surface of the specimen is mainly composed of V, Cr, C and O elements.
