主 题:Sn-doped BiOCl nanosheet High mass loading anode Synergistic H^(+)/Zn^(2+)co-insertion Fast ionic/electronic diffusion “Rocking chair”zinc-ion battery
摘 要:The development of insertion-type anodes is the key to designing“rocking chairzinc-ion ***,there is rare report on high mass loading anode with high ***,{001}-oriented Bi OCl nanosheets with Sn doping are proposed as a promising insertion-type *** designs of cross-linked CNTs conductive network,{001}-oriented nanosheet,and Sn doping significantly enhance ion/electron transport,proved via experimental tests and theoretical calculations(density of states and diffusion barrier).The H^(+)/Zn^(2+)synergistic co-insertion mechanism is proved via ex situ XRD,Raman,XPS,and SEM ***,this optimized electrode delivers a high reversible capacity of 194 m A h g^(-1)at 0.1 A g^(-1)with a voltage of≈0.37 V and an impressive cyclability with 128 m A h g^(-1)over 2500 cycles at 1 A g^(-1).It also shows satisfactory performances at an ultrahigh mass loading of 10 mg cm^(-2).Moreover,the Sn-Bi OCl//MnO_(2)full cell displays a reversible capacity of 85 m A h g^(-1)at 0.2 A g^(-1)during cyclic test.
