“…Figure a depicts the CV curves of PEDOT/EVMT-180 at different scan rates. In the potential range of 0–1 V, the current response increases with the augment of the scanning rate and shows an obvious redox peak, revealing excellent redox-pseudocapacitance properties and desirable rapid charge/discharge performance. , Figure b,c was obtained by fitting the CV curve of 2 mV s –1 . The capacitance charge storage mechanism of the PEDOT/EVMT-180 electrode can be accessed by the relationship between the peak current ( i ) and scan rate (ν) according to the formula: i = a ν b …”

“…For instance, W. B. Zhang's group synthesized novel CoB@clay hybrid composites by using various clay minerals (MMT, vermiculite (Ver), kaolinite, halloysite (Hal), palygorskite (Pal), and chlorite) via a facile liquid-phase reduction process. 158,159 It was found that the 2D layered structure and outstanding electrolyte affinity of MMT combined with the high conductivity of amorphous CoB endowed the CoB@MMT electrode with outstanding capacitive performance. Furthermore, it was also found that the adjustable interlayer spacing of MMT was beneficial for CoB loading and could accommodate the volume changes of the electrode.…”

The electrolyte-wettability of electrode materials in liquid electrolytes plays a crucial role in electrochemical energy storage, conversion systems, and beyond relied on interface electrochemical process. However, most electrode materials do not have satisfactory electrolyte-wettability for possibly electrochemical reaction. In the last 30 years, there are a lot of literature have directed at exploiting methods to improve electrolyte-wettability of electrodes, understanding basic electrolyte-wettability mechanisms of electrode materials, exploring the effect of electrolyte-wettability on its electrochemical energy storage, conversion, and beyond performance. This review systematically and comprehensively evaluates the effect of electrolyte-wettability on electrochemical energy storage performance of the electrode materials used in supercapacitors, metal ion batteries, and metal-based batteries, electrochemical energy conversion performance of the electrode materials used in fuel cells and electrochemical water splitting systems, as well as capacitive deionization performance of the electrode materials used in capacitive deionization systems. Finally, the challenges in approaches for improving electrolyte-wettability of electrode materials, characterization techniques of electrolyte-wettability, as well as electrolyte-wettability of electrode materials applied in special environment and other electrochemical systems with electrodes and liquid electrolytes, which gives future possible directions for constructing interesting electrolyte-wettability to meet the demand of high electrochemical performance, are also discussed.
