Summary TixCr1 − yFeyMn1.0 (x = 1.02, 1.05, 1.1, 0.05 ≤ y ≤ 0.25) alloys were prepared by plasma arc melting and annealing at 1273 K for 2 hours. The XRD results show that the main phase of all alloys is the C14 type Laves phase, and a little secondary phase exists in a mixture of the binary alloy phase. The lattice parameters increase with Ti super‐stoichiometry ratio increasing, whereas smaller lattice parameters emerge with increasing Fe stoichiometry content. Additionally, as the Ti super‐stoichiometry ratio decreases, the pressure‐composition‐temperature measurements indicated that hydrogen absorption and desorption plateau pressures of TixCr0.9Fe0.1Mn1.0 (x = 1.1, 1.05, 1.02) alloys increase from 3.15, 0.67, to 5.94, 1.13 MPa at 233 K, respectively. On the other hand, with the Fe content increasing in Ti1.05Cr1 − yFeyMn1.0 (0.1 ≤ y ≤ 0.25) alloys from 0.1 to 0.25, the hydrogen desorption plateau pressures increased from 1.41 to 2.46 MPa at 243 K. The hydrogen desorption plateau slopes reduce to 0.2 with Ti super‐stoichiometry ratio decreasing to 1.02, but the alloys are very difficult to activate for hydrogen absorption and cannot activate when the Fe substituting for Cr exceeds 0.2. The maximum hydrogen storage capacities were more than 1.85 wt% at 201 K. The reversible hydrogen storage capacities can remain more than 1.55 wt% at 271 K. The enthalpy and entropy for all hydride dehydrogenation are in the range of 21.0 to 25.5 kJ/mol H2 and 116 to 122 J mol−1 K−1, respectively. Our results suggest that Ti1.05Cr0.75Fe0.25Mn1.0 alloy with low enthalpy holds great promise for a high hydrogen pressure hybrid tank in a hydrogen refueling station (45 MPa at 333 K), and the other alloys of low cost may be used for a potable hybrid tank due to high dissociation pressure at 243 K and high volumetric density exceeding 40 kg/m3.

“…Recently, our paper showed that the electrochemistry capacity of the LaGaO 3 oxide can reach 220 mAh g −1 and suggested the possibility of using this oxide as new electrode materials in the Ni‐MH hydrogen batteries at high temperature (328 K) . The literature shows that there is a narrow relationship between temperature and electrochemical properties of hydrogen storage alloys of different kinds …”

Summary To obtain a novel negative electrode for nickel‐metal hydride rechargeable batteries, perovskite‐type oxide LaGaO3 was synthesized by the sol‐gel method. The electrochemical properties of the oxide were systematically investigated at different temperatures by using galvanostatic, chronoamperometric, and potentiodynamic polarization methods. We have selected 298, 313, and 328 K as room, intermediate, and high temperatures, respectively. The galvanostatic results showed that the discharge capacity of the oxide LaGaO3 increased with the temperature elevating during the first 3 cycles. This oxide has the highest discharge capacity of about 220 mAh g−1at high temperature. For room and intermediate temperatures, we observed that the discharge capacity maintains a constant about of 5 and 13 mAh g−1 for 298 and 313 K, respectively, when the number of cycles is increased. The electrochemical kinetic analysis indicates that the exchange current density and the hydrogen diffusion coefficient of the oxide LaGaO3 increase with the rise in temperature. The apparent activation energy (Ea) for hydrogen diffusion process and the activation energy (ΔrH*) for charge‐transfer reaction of the investigated oxide electrode LaGaO3 are estimated. The calculated values of the Ea and ΔrH* are 117.46 and 105 kJ mol−1, respectively. The above experimental results indicated that the kinetic properties of the working electrode have been significantly improved by the elevating of the temperature. The best electrochemical performance (faster activation and highest maximum capacity) of the oxide electrode is obtained at high temperature (328 K).

The present research work examines the electrochemical properties of CaNi4.8M0.2(MMg, Zn) type alloy applied as an anode in nickel metal hybrid batteries. Based on an extensive study of the CaNi4.8Mn0.2 compound prepared by mecano‐synthesis; under an argon atmosphere, with a variation of milling time and weigh ratio, using a Retsch PM400 type ball mill. The experimental results show that the excellent electrochemical properties were obtained for a milling time of 40 h and a ball‐to‐powder weight ratio equal to 8:1. Based on this study, we examined electrochemically the CaNi4.8M0.2(MMg, Zn, and Mn) compound according to the optimized parameters. Several methods, such as galvanostatic polarization and potentiodynamic polarization, were applied to characterize these electrodes. CaNi4.8M0.2(MMg, Zn, and Mn) electrodes were activated, respectively, during the first, second, and third cycles. The maximum discharge capacity was about 87, 60, and 96 mAhg−1 at ambient temperature. These electrochemical findings correlate with the kinetic results provided during a long cycle.
