A “one-for-three” strategy through a facile one-step hydrothermal engineering of commercial MoO3 for high-performance proton storage

Abstract: The sluggish diffusion kinetics of metal ions and irreversible structure transition of electrode materials lead to serious decay of electrochemical performance. In this work, a “one-for-three” strategy is demonstrated to...

“…[48] The polymer is a conductive and buffering agent to alleviate the structural fragmentation of MoO 3 during the cycle effectively. Liu et al [107] prepare polyaniline coated with MoO 3 by a simple one-step hydrothermal process. A thin layer of polyaniline (PANI) coated MoO 3 introduces oxygen vacancies and inhibits the dissolution of MoO 3 .…”

“…Composite with polymers is one of the effective strategies to enhance MoO 3 ‐based cathodes with structural stability and conductivity. The selection of polymers includes polyaniline (PANI), [107] poly (ethylene oxide) (PEO), [108] polypyrrole (PPy), [109] polyethylene glycol (PEG) [48] . The polymer is a conductive and buffering agent to alleviate the structural fragmentation of MoO 3 during the cycle effectively.…”

“…To meet the rapid development of high-speed electric vehicles and other high power devices, supercapacitors are highly desirable and attractive due to the fast charge/discharge rate, high power density, and superior cycling performance. Although carbon materials have been widely used in supercapacitors through electrical double layer capacitor behavior, the low specific capacitance and limited energy density hinder their electrochemical performance. Pseudocapacitive or battery-type materials, such as metal oxides/sulfides/hydroxides (M-O/M-S/M-OH) based on Faraday redox reactions, exhibit much higher theoretical capacitance than carbon-based materials. However, the electrochemical performance, especially the rate capability, still does not meet the expectation due to the poor electronic conductivity and sluggish reaction kinetics. , …”
