Li-Ion batteries (LIBs) dominate the energy storage market owing to their versatility and efficient energy storage. Also, for electric vehicle applications, batteries with better power, safety and cyclability are needed. To address the issues related to lower power density, lesser cyclability, low capacity retention, safety, cost etc. several modifications like nanostructuring, 3D and 2D architectures, doping, core shell particles, binder free electrodes, modified electrolytes and separators have been employed. Plasma technologies can reduce the number of steps and time required for the synthesis of nanoarchitectures and material modifications, hence a reduction in the cost required to produce LIBs against the high initial This article is protected by copyright.

This review paper aims at emphasising plasma enabled modification and synthesis techniques for LIB electrodes, separators, electrolytes and for recent advances like solid state and flexible batteries.

Carbon quantum dots (CQDs) are a new type of carbon nanomaterial that has recently attracted great attention as a potential competitor to standard semiconductor quantum dots. There are various ways to synthesis CQDs, and one of harmless way is undoubtedly green synthesis. In this study, hydrothermal synthesis based on the green way was employed to synthesize CQDs. The CQDs were obtained using the green leaves of the Stachys euadenia plant extract, an endemic species located in Turkey. The CQDs were characterized by fluorescent and UV‐Visible spectroscopy, and results confirmed blue emission (430–480 nm) and absorption around 280 nm. X‐ray photoelectron spectroscopy (XPS) analysis revealed C=C, C–N and C–O interactions. X‐ray diffractometer (XRD) patterns confirmed structure of carbon with a broad peak of (002) plane. High resolution tunneling electron microscopy (HRTEM) and dynamic light scattering (DLS) analysis was used to determine the shape and size of CQDs. The CQDs obtained from Stachys euadenia were employed as electrode materials for capacitor application, and they were tested in Swagelok‐type cell by cyclic voltammetry (CV) measurements. CQD capacitors exhibited 2.12 F/g charge and 1.24 F/g discharge capacitances were obtained with ~58% coulombic efficiency rate for the first cycle. Results highlights that CQDs are synthesized successfully by green synthesis method and can be used for capacitor applications.

“…As seen in Figure d, NiSb/NiTe displayed long-term cycle stability, remaining above 82% after 30,000 GCD cycles at 10 A g –1 . The NiTe nanosheets act as a volume strain buffer between the Ni substrate and NiSb, alleviating the volume inflation that occurs during the discharge/charge of the composite electrode, resulting in excellent cycling stability performances. ,− The resistances both before and after cycling are comparatively and analytically presented in Figure e. After 30,000 GCD test circles, volume expansion and a partially irreversible oxidation reaction of NiSb/NiTe resulted in a deterioration in properties and a change to high internal resistance.…”

In this paper, NiSb/NiTe/Ni composites were smoothly developed via the microwave method for supercapacitors. The synthesis of NiSb/NiTe crystals was revealed by X-ray photoelectron spectroscopy and X-ray diffraction. The analytic results of scanning electron microscopy and energy dispersive spectroscopy uncover the microscopic morphology as well as the constituent elements of the composites. Self-supported NiSb/NiTe is a supercapacitor cathode that combines high capacitance with excellent cycling stability. The obtained composite electrode displayed remarkable electrochemical properties, presenting a special capacitance of 1870 F g −1 (1 A g −1 ) and 81.5% of the original capacity through 30,000 times (10 A g −1 ) of the charging/ discharging process. Further, an asymmetric supercapacitor was prepared employing NiSb/NiTe as a cathode and activated carbon as an anode. NiSb/NiTe//AC exhibited a high energy density of 224.6 uW h cm −2 with a power density of 750 μW cm −2 and provided a favorable cycling stability of 83% after 10,000 cycles.
