“…Зажигание разряда осуществляется в газоразрядных камерах с различными типами и формами конфигурации электродов, включающие в себя системы: твердый−жидкий электроды [2][3][4][5], жидкий (проточный)−жидкий (непроточный) электроды [6], жидкий (проточный)−жидкий (проточный) электроды [7]. Наиболее распространенные схемы зажигания разряда осуществляются при погружении металлического электрода в электролит [8], либо при расположении металлического электрода на некотором расстоянии от поверхности электролита [9]. Давление окружающего воздуха, используемое при проведении исследований, ограничивается диапазоном 10 5 −10 3 Pa, так как при более низких давлениях начинается кипение раствора в электролитических ячейках газоразрядной камеры.…”

The work is devoted to the study of the characteristics of a low-temperature plasma of a high-frequency (HF) discharge (f = 13.56 MHz) ignited between metallic and electrolytic electrodes at atmospheric pressure. Burning of an RF discharge in a diffuse (volumetric) form is observed at the interface between the media between the electrodes. Numerical calculations of the electric field strength and the distribution of the volumetric power density of the Joule heat release before breakdown in a vapor-gas mixture near a metal electrode are presented. The discharge radiation spectrum, plasma composition, and electron density were studied by optical emission spectroscopy. The thermograms of the electrode surface under the conditions of an RF discharge are considered.

“…The most common discharge ignition schemes are implemented when a metal electrode is immersed in an electrolyte [8], or when the metal electrode is located at some distance from the electrolyte surface [9]. The ambient air pressure used in the studies is limited to the range of 10 5 −10 3 Pa, since at lower pressures the solution begins to boil in the electrolytic cells of the gas discharge chamber.…”

materials (mostly conversion-allying type, donated CA-types), such as SnS 2 , Sb 2 S 3 , and Bi 2 S 3 . [2] All of the cations and anions in CA-type materials could react with alkali ions, contributing to improvements in the theoretical capacity. For instance, through the MOF templates, multishell hollow structured Sb 2 S 3 displayed an excellent ion storage capacity of ≈1000 mAh g −1 at 0.1 A g −1 . [3] However, from previous reports, it could be noted that serious volume expansions would bring about the separation of two phases (about the alloy phase and anion phase), further resulting in the shuttling of polysulfide, accompanied by frustrating capacity fading. [4] However, note that materials with both long-term cycling stabilities and higher capacity are urgently anticipated to meet the demand of ESSs.To solve the issues above, a series of tailoring methods were proposed, mainly containing the control of architecture and the introduction of coating layers. [5] Nanosized materials with a good distribution induce a reduction in structural stress during cycling, facilitating the alleviation of volume expansions. In addition, owing to the increase in the exposure active surface, a wide energy distribution would result, boosting the fast occurrence of redox reactions (that is, pseudocapacitive behaviors), finally bringing about enhanced rate properties. According to their dimensionalities, their architecture can be divided into 1D rods or tubules, 2D sheets or layers, and a 3D framework. Among them, the 3D structure with a unique architecture displayed a relatively higher energy density, which is beneficial for practical applications (such as sphere-like LiCo 1/3 Ni 1/3 Mn 1/3 O 2 , LiFePO 4 , and graphite). [6] To further improve their electrochemical properties, a coating process was introduced, where various kinds of coating matrices with various merits play crucial roles. Recently, a series of coating matrices were explored, such as inorganic materials (AlF 3 , MgF 3 , and so on), organic materials (polypyrrole, polyaniline), and carbon materials. [7] Interestingly, the carbon matrix displayed many traits, such as a strong confinement effect and ionic conductivity. [8] The traditional carbon matrix can be divided into 0D carbon particles, 1D carbon nanotubes, and 2D graphene. [9] However, their effect on electrode materials has not been systematically explored. Meanwhile, their rich groups on As potential candidates, metal sulfides display strong storage abilities but suffer from serious volume swelling and polysulfide shuttling. Especially rich-sulfur materials, inferior reversible conversion reactions (from MS 2 to MS with S) can bring about major formation of sulfur. Herein, cubic-like Sn-Co-S materials with SnO 2 as catalyst are designed with various dimensional carbon. The asresulted samples display uniform distributed particle size (≈5 µm), while crosslinked Sn-Co-S@carbon is successfully formed due to its rich surficial groups. Significantly, the formation of chemical bonds about Sn/Co-S-C is noted...
