In this paper, polyaniline/FeFe(CN)6(PANI-FeFe(CN)6) composites were prepared by a simple in-situ oxidation polymerization in perchloric acid (HClO4) solution in which the obtained polyaniline (PANI) self-assembled to form the tube-like morphology, while FeFe(CN)6 with perfect face-centered cubic lattice (FCC)-type structure was well-dispersed in the obtained PANI matrix. As the cathode of lithium ion battery, PANI-FeFe(CN)6 composite demonstrates the improved specific capacity, cycling stability and current rate performances. For PANI-FeFe(CN)6 composite prepared by feed mass ratio of FeFe(CN)[Formula: see text] Aniline to 80:100 (PANI-FeFe(CN)6(80%)), it still remained 95.7[Formula: see text]mAh/g of discharge capacity after 100 cycles, indicating its excellent cycling performances. Especially, its specific capacities were 95.9, 98.8, 91.4, 83.6 and 72[Formula: see text]mAh/g at the current density of 20, 50, 100, 200 and 500[Formula: see text]mA/g, which were obviously higher than that of PANI or FeFe(CN)6, respectively. The improved thermal stability and electrochemical performances for PANI-FeFe(CN)6 composites could be ascribed to the formed interaction between PANI and FeFe(CN)6 components and the enhanced electrical conductivity, which made it a potential candidate as the cathode of lithium battery.
