Electrophoretic deposition (EPD) is an excellent surface coating approach widely investigated for applications ranging from solar cells, batteries, electrochemical capacitors, solid oxide fuel cells, sensors, molecular sieves, corrosion‐resistant coatings, and biomedical materials. On the other hand, superhydrophobic (SHPC) surfaces have enticed substantial recent research interest owing to their superb surface properties. Here, we provide a comprehensive review of electrophoretic‐deposited SHPC coatings. Concise descriptions of EPD and superhydrophobicity are provided first, followed by a brief mentioning of works reported on electrophoretic‐deposited SHPC coatings by one‐step or two‐step processing (§2.1). The next section (§2.2) delivers a comprehensive description of these reports based on the micro/nanoparticles used. Works reported in specific applications such as anti‐corrosion, biomedical, and oil‐separation are described in §2.3. Future scopes of research also presented.

“…Electrophoretic deposition (EPD) is a coating process in which colloidal particles suspended in a liquid medium migrate under electric filed and are deposited on an electrode with opposite charge [116–117] . The mobility of colloidal particles is influenced by several factors including the dielectric constant and viscosity of the fluid, the potential gradient and the zeta potential of the colloidal particles [118] . The above parameters could be described via the Henry equation [Eq.…”

“…In general, to synthesize high‐performance electrode materials via EPD method, there are several parameters should be optimized and post‐treatments should be implemented: [118,120–121] (a) operation conditions such as applied voltage, inter‐electrode distance and deposition time; (b) characteristics of a suspension like the concentration of the colloidal particles and charging/stabilizing agents; (c) subsequent heat treatment process.…”

Fabrication of binder‐free electrodes is an effective way to increase the performance of electrochemical energy storage (EES) devices, such as rechargeable batteries and supercapacitors. In traditional electrodes, the binder is usually electrochemically inert and has weak interactions and interfaces between binder and the active material, which increase “dead mass” and directly affect the performance of energy storage system. The binder‐free electrode can provide well‐designed electrode material structure enables well connection between active materials themselves and current collectors. In addition, without insulating binder, electron and electrolyte ions can transfer more efficiently within the electrode materials. Here, we reviewed research efforts in using various techniques involving chemical, physical and electrical methods to fabricate binder‐free electrodes. For every technique, we first briefly describe their principle and involved factors that influence the performance of as‐fabricated binder‐free electrodes and summarize advantages and disadvantages. Next, we reviewed several works which have used this technique to fabricate binder‐free electrodes. Further, the effect of well‐crafted structure design on the properties of energy storage performances including rate capability, and cycle stability was highlighted. Last, we offer our perspectives on the challenges and potential future research directions in this area. We hope this review can stimulate more research to design and synthesize the binder‐free materials for EES devices.

“…The 1st and 10th charge-discharge profiles of the cells cycled at 0.1 C are shown in Fig. 4 (a), where the first discharge plateau is attributed to the reduction of solid sulfur, with S 8 molecules, to soluble high-order LiPSs (Li 2 S n , 4 ≤ n ≤ 8), while during the second plateau the high-order LiPSs are converted into insulating and insoluble lithium sulfides (Li 2 S 2 /Li 2 S) [29] . It can be seen that the presence of the EPD-CNT film leads to a significant increase in the discharge capacity by contributing to the appearance of the second voltage plateau (which did not appear in CFP/S), indicating the capability of the homogeneous EPD-CNT layer to support the reduction reaction of soluble LiPSs and Li 2 S 2 /Li 2 S precipitation.…”
