“…6c. However, the approach presented, to improve the interaction between substrate and ppy polymerized by physical deposition by plasma could be applied to other systems that have been published by other authors, such as carbon-polymer graphene, carbon-polymer-polymer and carbon-polymer-metallic oxides [15,[29][30][31], to say the few.…”

In this study, new polypyrrole films (ppy) were synthesized using a physical plasma deposition (PAPVD) system; where the equipment design and methodology for plasma-assisted pyrrole polymerization were improvement. The morphology, functional groups, and thermal stability of the polymer network films were characterized by X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) techniques, respectively. The electrochemical properties of the films as capacitor were evaluated by cyclic voltammetry and electrochemical impedance spectroscopy. The results observed by SEM showed that the ppy 100W-1 and ppy 100W-2 films present uniformity in their structure. The analyses of TGA and DSC confirmed the improvement in stability; meanwhile for 100W-1 film, the presence of ppy bonds was corroborated by XPS. Plasma-activated ppy 100W-1 film exhibited higher capacitance and minor Rct resistance than that obtained for ppy 100W-2 film. The specific capacitances values of ppy 100W-1 and ppy 100w-2 films are 196 and 150 F/g in 1 M KCl. After charging and discharging tests of 1000 cycles at 5 mA cm−2 current density of ppy 100W-1 film retains 89% of its initial capacitance. Therefore, ppy 100W-1 film showed to be a promising material for use as an electrochemical capacitor.

“…Separators are typically manufactured based on polymer materials, the most used being polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC)), and polyvinylidene fluoride (PVDF) and co‐polymers and different processing techniques such as wet processes and dry processes such as extrusion, [ 85 ] electrospinning, [ 86 ] nonwoven techniques, [ 87 ] atomic layer deposition, [ 88 ] solvent casting with thermally induced phase separation, [ 89 ] and non‐solvent phase separation processes (NIPS), [ 90 ] among others [ 91 ] where its surface can be modified by plasma treatment. [ 92 ] The thickness of the separators typically varies between 25 and 40 µm, depending on the type of battery, they show a degree of porosity larger than 40% with an average pore size below 1 µm and are stable at temperatures up to 150 °C. Additionally, to improve the thermal and mechanical properties and wettability of the conventional separators based on PE and PP, new separators based on covalent organic framework (COF) into poly(arylene ether benzimidazole) (OPBI), [ 93 ] polyacrylonitrile (PAN) composite separators with cellulose acetate and nano‐hydroxyapatite, [ 94 ] PAN with aluminum diethylphosphinate (ADEP), [ 95 ] polyimide (PI) polymer, [ 96 ] PI with polyethylene oxide (PEO) processed by electrospinning technique, [ 97 ] PI with zirconia (ZrO 2 ), [ 98 ] PI with graphene, [ 99 ] PI with hexagonal boron nitride, [ 100 ] PI with nano‐tiO 2 , [ 101 ] PI with organic montmorillonite (OMMT), [ 102 ] PEO with para‐aramid nanofibers (ANFs), [ 103 ] PVDF/SiO 2 , [ 104 ] poly(ethylene glycol) diacrylate (PEGDA), [ 105 ] polyurethane separator coated Al 2 O 3 particles, [ 89a ] and poly(vinyl alcohol) with nano architecture halloysite nanotubes (NHNTs) composite separator (OPVA/NHNTs separator, [ 106 ] and new coatings of boehmite (γ‐AlO(OH)) nanofibers, [ 107 ] inorganic oxide solid electrolyte layers (Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 , LATP), [ 108 ] SiO 2 with acrylamide (AM), [ 81a ] Ca 3 (PO 4 ) 2 inorganic layer, [ 91 ] polyimide microsphere, [ 109 ] and plasma treatment plus zwitterion grafting [ 110 ] were developed.…”

For the proper design and evaluation of next‐generation lithium‐ion batteries, different physical‐chemical scales have to be considered. Taking into account the electrochemical principles and methods that govern the different processes occurring in the battery, the present review describes the main theoretical electrochemical and thermal models that allow simulation of the performance of lithium‐ion batteries, including different materials and components (electrodes and separators) and battery geometries. As the separator plays an essential role in the performance and safety of lithium‐ion batteries, the recent theoretical simulation work for this battery component are shown, with particular emphasis on morphology, dendrite growth, ionic transport, and mechanical properties. Further theoretical simulations and modeling of this battery component are still required for improving performance, taking into consideration varying geometric parameters such as pore size, porosity, and tortuosity as well as the optimization of the lithium diffusion process and ionic conductivity value. Theoretical simulations of battery separators will play an essential role in the new generation of lithium‐ion batteries, allowing the improvement of their performance while reducing experimental probes and time.

“…Nevertheless, the required high temperature is harmful for the Zn substrates due to the low melting point of 419.6 C. In recent years, the plasma-assisted deposition has received increased attention as the high momentum and chemical activity of the active particles in plasma can greatly reduce the processing temperature. 33 For example, Lu et al 23 prepared CuZn 5 , AgZn 3 and AuZn 3 alloy layers on Zn foil through plasma sputtering Cu, Ag and Au targets without heating, respectively. Nonetheless, the uneven distribution of ion bombardment energy in tradition glow discharge can also bring some undesirable effects (e.g., edge effects, hollow cathode damage, and arcing) to damage the Zn foils (Figure S2).…”

The problematic Zn dendrite for Zn anodes remains a great challenge.Constructing an artificial Cu-Zn alloy layer is one of the most potential solutions. However, it is still challenging to prepare an ideal Cu-Zn alloy layer with good morphology and controllable thickness. Herein, a special plasmabased method of active screen plasma (ASP) is first reported to create a hexagonal close-packed CuZn 5 alloy layer with controllable morphology and thickness. Meanwhile, a "vaporization-redeposition" mode is proposed to illustrate the alloying process. Based upon system analysis, the CuZn 5 layer with good uniformity and appropriate thickness can regulate the behavior of Zn-ion at electrode/electrolyte interface. The former homogenizes the electric field distribution, while the latter enhances de-solvation ability of Zn-ion, facilitating Znion diffusion. Consequently, the CuZn 5 -coated Zn anodes display lower polarization potential and longer cycling life. Such CuZn 5 -coated Zn anodes enable an outstanding cycle stability for Zn-based devices, and the pouch devices also deliver practicality.
