Abstract: A composite structure anode for lithium ion battery (LIB) was investigated. The composite anode was prepared by electrodepositing Sn-Sb alloy on a template-like electrode which was obtained by forming a spange-like micro-porous membrane on a copper foil via a mixed phase inversion process, and then annealing in the atmosphere of N2. SEM and XRD results showed that composite structure of the anode was consisted of electrodeposited Sn-Sb alloy dispersing in a PAN-pyrolyzed conjugated conducting polymer gridding, which was connected with the Cu foil through transition alloy layer formed by heat-treatment. By comparison, the composite anode presented more reasonable microcosmic structure, better cycling performance and higher C-rate Performance than that obtained via directly electrodeposited Sn-Sb alloy on a Cu foil and then heat-treatment .
