“…Similarly, the increment of the cell temperature is another factor that benefits the electrochemical reaction (see Figs. 4 and 5), leading to an improved discharge capacity as reported for different perovskite-type compositions [27,59,66,77,78]. These results show an advantage over intermetallic compounds whose electrochemical capacity is [84] affected by the increment of the operating temperature [85].…”

“…The LaGaO 3 consists of a single phase that crystallizes in an orthorhombic structure. This oxide first presents a discharge capacity with a maximum value of 220 mAhg -1 at 333 K, which decreases after the first three charge/discharge cycles [66,88]. This degradation phenomenon with cycling has been observed as well in others RE-perovskite-type oxides [27].…”

“…6a, b. Interestingly, XRD patterns, like in Fig. 6, are typical of perovskite electrodes after galvanostatic charge/discharge cycling, which reveals the structural stability of these compounds during the hydrogen absorption/desorption process [27,59,66,78]. Perovskite-type oxides present a small lattice expansion when compared with intermetallic alloys.…”

“…This fact might result in an advantage for perovskite-type electrodes since they could be resistant to crack formation and spalling due to the lattice expansion during electrochemical cycling. In this sense, the few morphological studies about perovskite-type electrodes suggest that those are not free of damage after hydrogenation [66], Fig. 7.…”

“…Sol-gel methods, especially, the well-known 'Pechini method', have been another option for the synthesis of perovskite-type oxides in previous studies [66,67]. This method involves the mixing of perovskite precursors in nitrate and oxide form followed by the addition of a chelating agent, ethylene glycol as the sol-forming product, desiccation and calcination.…”

Rare-earth perovskites-type oxides are compounds with the general formula ABO 3 . There are many industrial and research applications related to their properties such as photocatalytic activity, magnetism, or pyroferro and piezo-electricity, and interest in these compounds in the field of energy storage and conversion is growing. Rare-earth perovskite-type oxides may be used in nickelmetal hydride (Ni/MH) battery technology because these materials may store hydrogen in strong alkaline environments, and also because of their abundance and low cost. In this review, the use of rare-earth perovskite-type oxides in Ni/MH batteries is described, starting from their crystalline structure and production methods. In each category, a description concerning the latest advances and future research direction is presented. Electrochemical performance of the perovskite-type electrodes is reviewed extensively. In addition, various strategies for enhancing their hydrogen storage capacity as a negative electrode in hydrogen batteries are discussed. Drawbacks and challenges of this technology are also presented.

The physico‐chemical performance of the novel anode LaGaO3 for Ni/MH accumulators was studied using the electrochemical impedance spectroscopy (EIS) method during cycling. The measured EIS data of the perovskite oxide are fitted according to the proposed equivalent circuit representing various processes involved in the mechanism of hydrogenation/dehydrogenation reactions of the oxide. Different kinetic elements such as current density I0, charge transfer resistance Rct, hydrogen transfer resistance Rht, double layer capacitance Cdl, and mass hydrogen diffusion Y0 were estimated under cycling. The EIS results relieved that current density I0 of the oxide increases quickly during the activation process and its maximum value is obtained at the second cycle (377.67 mA g−1). The degradation of the charge transfer rate of the oxide after activation can be ascribed to the corrosion of the electrode/electrolyte interface. The variation of the Warburg impedance Y0 could be attributed to the change in the morphological and the structure of the working electrode over cycling. The EIS analysis relieved that electrochemical behavior of the oxide is controlled by the charge‐transfer rate and the modification of the electrode surface.
