“…Note that the ultrathin coating of Nafion did not significantly affect the overall mass of the electrode. [147] Regarding cathodes, E-spray is preferred because of its precise control over morphology, which eases Li diffusion during insertion and extraction. Anode materials from carbon, transition metal oxides (TMOs) and their mixtures can also be deposited by E-spray.…”

The electrostatic spray method is a promising nonvacuum technique for efficient deposition of thin films from solutions or dispersions. The multitude of electrostatic spray process parameters, including surface tension, viscosity, and conductivity of the liquid, applied voltage, nozzle size, and flow rate, make electrostatic spray deposition very versatile for the morphological engineering of nanostructured films. The current state-of-the-art in electrostatic spraying can produce exceptional morphologies. Such tailoring of morphologies is notably useful in electrochemical applications where high electrolyte-accessible surface area often improves performance. Interesting morphologies of metal oxides and their composites are highlighted, including nanopillars, nanoferns, and porous microspheres produced by electrostatic spraying to enhance energy conversion and storage performance. The physics associated with the electrostatic spray process and morphology control using it are also presented. The manuscript highlights the potential of electrospray processing for producing thin films of controlled microstructure, from ultrasmooth layers in organic photovoltaics and perovskite photovoltaics to hierarchical nanostructured films for anodes and photoanodes. It aims to help researchers appreciate essential aspects of electrostatic spray deposition efficiency, process control, and morphology engineering for energy conversion (e.g., solar cell, fuel cell, and photoelectrochemical cell) and energy storage (e.g., lithium-ion battery and supercapacitor) electrodes.

“…The key points of research for fabricating a thin cathode are 1) material selection (e.g., active material, binder, solvent, and dispersant) and 2) manufacturing method (e.g., tape casting, screen-printing, or spraying). With respect to these two issues, processing methods such as tape casting, 75,76) screen-printing, [77][78][79][80][81][82] and spraying [83][84][85][86][87][88][89] have already been sufficiently investigated in other fields. Of course, appropriate equipment modifications are necessary depending on the application, but this is considered less important than material selection.…”

Thermal batteries are reserve batteries with molten salts as an electrolyte, which activates at high temperature. Due to their excellent reliability, long shelf life, and mechanical robustness, thermal batteries are used in military applications. A high-performance cathode for thermal batteries should be considered in terms of its high capacity, high voltage, and high thermal stability. Research progress on cathode materials from the recent decade is reviewed in this article. The major directions of research were surface modification, compounding of existing materials, fabrication of thin film cathode, and development of new materials. In order to develop a high-performance cathode, a proper combination of these research directions is required while considering mass production and cost.

“…The sulfonated groups in the side chain allow the transport of Li + ions [11][12][13][14][15] and hinder the shuttle process of the polysulfide anions, which are formed during the discharging process at the sulfur cathode, towards the Li anode. Nafion™ was also used in other Li batteries as a separator [16] or as a protective layer for the cathode [17]. Nafion™ solutions are commercially available, even if quite expensive [18], and easily applicable by spraying or roll coating processes [17,19] on electrodes or separators.…”

Nafion™ solutions are commercially available, even if quite expensive [18], and easily applicable by spraying or roll coating processes [17,19] on electrodes or separators. The Nafion™ layer improves the wettability of the separator, thanks to the polarity of the molecule and the adhesion properties between electrode and separator, the latter being extremely important in the lamination process.…”

The adhesion between electrode and separator is a key feature in cell assembly. Nafion™-coated separators for water-processed LiNi0.5Mn1.5O4 (LNMO) electrodes are here proposed as an alternative to the polyolefin separators. Specifically, polyolefin separators are modified with Nafion™ solutions and their adhesion to high-potential LNMO electrodes is investigated. The physicochemical properties of the Nafion™-coated separator and its electrochemical performance in Li/LNMO cells are discussed and compared to those obtained with polyolefin Celgard® (Charlotte, NC, USA) PP2075 separator. Improved adhesion and cycling stability, which could be further enhanced by a mild lamination process, were demonstrated with a thin layer of Nafion™ (0.1 mg cm−2).
