主 题：Dual-ion Battery Anode materials MoS_(2) High rate performance
摘 要：Dual-ion batteries(DIBs)have attracted great attention due to their affordable prices,environmentalfriendliness,and high operating ***,the conventional graphite anode in DIBs has draw-backs such as unsatisfactory capacity and worrying ***_(2)is considered to be a competitive anodematerial that exhibits large capacity due to its unique layered structure for cation insertion/***,the sluggish reaction kinetics of MoS_(2)does not match the cathode side,which makes theconstructed full DIBs show poor rate ***,a flower-like MoS_(2)/polyaniline composite electrode(MoS_(2)-PANI)where PANI was grown in situ between layers of MoS_(2)nanosheets was *** thisdesign,the inserted PANI can broaden the layer distance of MoS_(2)to facilitate cation diffusion and pre-vent the restacking of ***,PANI is also expected to increase the conductivity andrelieve the volume changes during repeated charge/discharge *** from that,the MoS_(2)-PANIelectrode delivered a reversible capacity of 561.91 mA h g^(-1) at 5 A g^(-1) in half-cell ***,whencoupled with a mildly expanded graphite(MEG)cathode,the obtained MEG//MoS_(2)-PANI DIB shows ex-cellent rate ability with a reversible discharge capacity of 86.62 mA h g^(-1) and a desirable energy densityof 308.83 W h kg-1 at 20 *** results provide some inspiration for the design of high-rate DIBs.
