However, a serious irreversible capacity decay after the first cycle of such materials inhibits their widespread applications in rechargeable batteries. In this work, a highly porous (3D) quaternary Cu2ZnSnS4 (CZTS) film was synthesized through a facile solution pyrolysis method. An initial discharge capacity of 1154 mA h g-1 and a stabilised value of about 680 mA h g-1 after 40 cycles at a current rate of 100 mA g-1 were achieved. Such significantly improved capacity and stability (especially for the first several cycles) indicate the great advantages of this 3D nanostructured CZTS electrode for advanced secondary lithium batteries. © 2013 The Royal Society of Chemistry.||Source Title:||Journal of Materials Chemistry A||URI:||http://scholarbank.nus.edu.sg/handle/10635/86389||ISSN:||20507488||DOI:||10.1039/c3ta11022b|
