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.

Rate Performance

Tin oxide/sponge carbon composite (SnO2/C) is synthesized by solvothermal reaction. The expected electrode materials are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectrum. Related electrochemical properties are carried out by battery comprehensive testing system. The composite could remain its specific capacity at 660.5 mAh g−1 after 200 cycles and behaved superior rate performance. The experimental results show that SnO2/C composite not only owned improved conductivity but also stable frame structure during lithiation/delithiation processes. So SnO2/C composite behaved higher reversible specific capacity and rate performance than those of pure SnO2 or SnC2O4. Based on its outstanding electrochemical performances, the SnO2/C anode electrode is a hopeful candidate for future application in lithium ion battery system.

Face Centered

The FeCoNiCrTi0.2 high-entropy alloys fabricated by vacuum arc melting method, and the annealed pristine material, are face centered cubic structures with coherent γ’ precipitation. Samples were irradiated with 50 keV He+ ions to a fluence of 2 × 1016 ions/cm2 at 723 K, and an in situ annealing experiment was carried out to monitor the evolution of helium bubbles during heating to 823 and 923 K. The pristine structure of FeCoNiCrTi0.2 samples and the evolution of helium bubbles during in situ annealing were both characterized by transmission electron microscopy. The annealing temperature and annealing time affect the process of helium bubbles evolution and formation. Meanwhile, the grain boundaries act as sinks to accumulate helium bubbles. However, the precipitation phase seems have few effects on the helium bubble evolution, which may be due to the coherent interface and same structure of γ’ precipitation and matrix.
