“…Figure shows the ATR‐FTIR spectra of cyclonic plasma deposited 316 stainless steel samples compared with undeposited 316 stainless steels. The main features of the ATR‐FTIR spectra include two chemical groups: a peak in the region of 801 to 845 cm −1 corresponding to SiRx (R represents methyl group) and a peak in the region of 980 to 1230 cm −1 corresponding to Si–O–Si. From ATR‐FTIR analysis, the noticeable organic silicon feature such as Si–O–Si and SiCH 3 dominate the atmospheric pressure plasma deposited 316 stainless steels.…”

Cyclonic atmospheric pressure plasma is developed to synthesize the organosilicon nano-coating on 316 L stainless steel surface with hexamethyldisilazane (HMDSN) and HMDSN/N 2 monomers. The modified 316 L stainless steel surface characteristics of cyclonic plasma deposited organosilicon nano-coating were evaluated by the static contact angle measurement, FTIR, SEM, AFM, and XPS detections. The chemical analysis with FTIR and XPS depicts that cyclonic plasma deposited nanocoating obtains the relatively inorganic characteristics. The surface morphological determination with SEM and AFM refers cyclonic plasma deposited 316 L stainless steel surface roughness alteration with switching monomer inputs. This study shows the potential of chamber-less deposition to create the plasma deposited organosilicon nano-coating for 316 L stainless.

“…This shows that the electrolyte solution is more stable in the plasma-treated separator than in the untreated separator. 28,29) Figure 8 shows the results of the charge-discharge characterization of Li-ion batteries using the plasma-treated and untreated PE separators. Charge and discharge tests were conducted between 2.0 and 4.0 V at 0.1 C rates.…”

In this paper, we describe the surface transition of the polyethylene (PE) separator used in lithium-ion batteries treated by low-pressure nitrogen plasma discharge. The nitrogen-plasma-treated PE separator was characterized by contact angle measurement, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy. The electrochemical performance of the lithium ion batteries fabricated with the nitrogen-plasma-treated separator was also evaluated. Results showed that polar functionalization groups were induced on the PE surface by the nitrogen plasma discharge, causing the surface to become hydrophilic. The increases in surface wettability and surface free energy result in electrolyte retention improvement. Moreover, the nitrogen plasma-treated PE separator leads to superior performance in lithium-ion battery assembly.

“…In a demonstration of the advantages of atmosphericpressure plasma, Tseng et al have shown that the hydrophilicity of the separator can be tailored by controlling the plasma power input during the surface activation. [109] Qin et al used a reactive atmospheric pressure plasma in a binder-free, roll-to-roll configuration to coat PE separators with a SiO x C y H z nanoparticulate film. [110] The schematic is shown in Figure 35.…”

Li‐ion batteries (LIBs) are currently the most preferred energy storage devices in portable applications. Recent surge in the production of electric vehicles in the wake of the current global warming scenario has strongly increased the demand for LIBs, thereby reinforcing the need for new battery chemistries as well as making the existing production chain more efficient and sustainable. Several new technologies are explored to achieve these goals. Among them, plasma technology has the potential to simplify the synthesis and modification of battery materials, enable ‘dry’ and ‘green’ processing that eliminate the need for solvents that are often toxic, expensive, flammable, and energy‐intensive. In this review, we have attempted to provide an overview of state‐of‐the‐art (scientific) research and development with respect to the application of plasma‐based processes in the synthesis and modification of materials for battery components. We have explored various applications wherein plasma‐based processes have been demonstrated in the processing of electrode materials, electrolytes, and separators in addition to the recent developments in the context of solid‐state and flexible batteries. Our analysis shows that plasma‐based technologies are slowly but steadily gaining attention in these areas. Several technical and conventional issues remain, which require innovations at the conceptual as well as engineering levels. Technical issues include the selection of appropriate plasma type and precursors, plasma density, selectivity, and a preferable shift from vacuum to atmospheric conditions. The conventional issues include the practical difficulties in converting or adapting the assembly lines to plasma‐based technology. From a business perspective, all that matters is the cost per mAh g−1 of energy produced, for which, unfortunately, we do not have sufficient quantitative data yet with regard to the materials processed by plasma‐based technologies. However, the battery manufacturing sector is now open for innovations like never before. Therefore, it remains to be seen how plasma technologies embrace this opportunity and penetrate the battery production sector, where the key parameters are efficiency and cost‐effectiveness. Would ‘giving it the plasma touch’ bring added value to the battery manufacturing processes? That is the question we try to address in this review.
