多级ZnO纳米片/Fe负极的制备及锂电性能
Preparation and Electrochemical Performances of Hierarchical ZnO Nanosheets/Fe Anode for Lithium Ion Battery
摘要
Abstract
Hierarchical ZnO nanosheets (ZnONS) were produced on Fe foil by electrochemical reduction of NO3-, chemical deposition of Zn(OH)2 and subsequent hydrolysis reaction. Its micro-morphology, microstructure, electrochemical Li-storage performance and reaction mechanism were investigated. The results showed that hierarchical ZnONS form and firmly attach onto the surface of Fe foil. Furthermore, the hierarchical ZnONS anode delivered an initial charge capacity of 633 mA·h/g and discharge capacity of 1564 mA·h/g; at the second cycle, its charge and discharge capacities become to be 564 and 595 mA·h/g, respectively;even after 50 cycles, the discharge capacity remains over 200 mA·h/g, presenting high cyclic performance and rate performances. The large initial irreversible capacity loss of the hierarchical ZnONS anode is believed to be originated from the decomposition of electrolyte and the formation of solid electrolyte interface (SEI) film.关键词
