As a cathode material for sodium ion batteries, NaMnPO4/C nanocomposite is successfully synthesized by the combination of spraying drying and high temperature sintering methods. The crystal structure of the as-synthesized phosphate material is confirmed as the natrophilite NaMnPO4, which possesses orthorhombic symmetry and Pmnb space group. It is shown that the precursors are hollow spherical particles and the obtained product consists of micro-scaled secondary particles, which are composed of NaMnPO4 nanocrystallites (tens of nanometres) and amorphous carbon networks. The ionic and electronic conductivities of NaMnPO4 are both effectively enhanced with the help of this …

Solid oxide fuel cell (SOFC) directly operating on hydrocarbon without external reforming has the potential of greatly speeding up the application of SOFCs for transportation. In this paper, a three-layer structure anode was fabricated by tape casting and screen printing method. The addition of Cu-LSCM-CeO2 to the supported anode surface presented better performance running on H2 and ethanol. The maximum power densities were 511 and 390 mW?cm-2, respectively, running on H2 and ethanol at 750 °C. No significant degradation was observed on the anode. Consequently, the Cu-LSCM-CeO2 catalyst layer on the surface of the …
