Electrochemical Behaviors

N-doped carbon covering on the surface of VN inhibits the oxidation of VN in alkaline electrolyte and increases the electrical conductivity of composite. Therefore, favorable electrochemical behaviors of the V2O3/C//VN/NCS device are exhibited.

The thermal expansion coefficient of LaCo1−xFexO3 averaging between 25 and 1000 °C decreased linearly with the Fe content, x. The thermal expansion of LaCo1−xNixO3 decreased with increasing the Ni content, but those for x = 0.67 and 1.0 were almost identical at 1000 °C due to the transition of the crystal system of LaNiO3. The behavior of thermal expansion was interpreted in terms of the formation enthalpy of the perovskites and the bond length between a B-site cation and an oxide anion. LaCo0.67Ni0.33O3, which has the electrical conductivity of 4 × 102 S/cm, could be a good candidate for the air electrode material.

In this work, ultrafine powders of b-FeOOH and Fe3O4 have been obtained by the precipitation method. The values of the specific surface area for materials b-FeOOH and Fe3O4 are 101 and 135 m2/h. Frequency dependences of specific electrical conductivity have been obtained in the temperature range of 20-150 oC. It has been found that the materials show a superlinear dependence (SPL). In addition, the crossover energies from dc to JPL and from JPL to SPL have been calculated: Edc = 0.55eV, Ep1 = 0.51eB, Ep2 = 0.16eB and Edc = 0.22 eV, Ep1 = 0.21eB, Ep2 = 0.1 eB. Potentiodynamic studies have been performed at a scan rate from 1 mV/s to 50 mV/s. The b-FeOOH electrode material showed a specific capacitance value of 80 F/g at a scan rate of 1 mV/s, while the specific capacitance of the Fe3O4 material reached 32 F/g. Galvanostatic measurements have been done for discharge currents of 0.05 A/g, 0.1 A/g -  0.25 A/g. b-FeOOH sample is characterized by the maximum specific energy value of 8 W h/kg at the value of specific power equal to 20 W/kg, and Fe3O4 material is characterized by the maximum specific energy of about 3.5 W h/kg.
