Coupling electrode materials with carbon substrates to construct flexible aqueous Zn-ion batteries (ZIBs) with excellent electrochemical performance is an attractive research focus. However, further improving the Zn 2+ /electron diffusion kinetics in such systems is still desirable. Herein, we present a novel hydrophilic carbon substrate that employs acid-treated natural halloysite and carbon nanotubes for the first time as structural and interfacial modifiers for loading V 3 S 4 as a composite cathode (denoted as HCC-V 3 S 4 ) for flexible ZIBs. The devices exhibit a high specific capacity of 148 mA h•g −1 under a current density of 0.5 A•g −1 (95% retention after 200 cycles), excellent rate performance, and a high energy density of 155.7 W h•kg −1 , together with a highpower density of 5000 W•kg −1 . The promising electrochemical property can be associated with the formation of the hydrophilic surface/interface and with the good conductivity of the composite electrode, which increases the Zn 2+ /electron transmission rate. Owing to the cost-effective design of the flexible substrate and the ZIB's impressive electrochemical performance, the fabricated device shows good potential applications in portable and wearable electronics.
GA can inhibit the proliferation of A375 cells and induce their apoptosis, which may be related to the up-regulation of the Bax/Bcl-2 ratio and caspase-3 activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
