“…Similarly, Yartys et al constructed a 10-cell bipolar NMHB with the output voltage of 12.5 V. [46] Such an assembled configuration of highvoltage cell is schematically shown in Figure 3. Subsequently, Deng and co-workers [47][48][49] performed the variety of improvements to advance BEs for NMHBs. For example, a gas chamber was added to a bipolar NMHB.…”

The development of advanced rechargeable batteries provides a great opportunity for basic and applied researchers to collectively overcome challenging scientific and technological barriers that directly address a critical need for energy storage. In addition to novel battery chemistries often scientifically reviewed, advanced battery structures via technological innovations that boost battery performance are also worthy of attention. In this context, bipolar electrodes (BEs) are capable of improving the specific power, simplifying cell components, and reducing manufacturing costs for rechargeable batteries. By focusing on the fundamentals and applications of BEs in rechargeable batteries, the rational utilization of BEs from an academic perspective is considered. The progress and challenges of BEs are discussed and summarized in detail. Key techniques and materials for enabling BEs are highlighted and an outlook for the future directions of BEs that involve emerging concepts, such as wearable devices, all‐solid‐state batteries, fast spraying fabrication, and recyclable secondary batteries, is also presented.

“…Materials composed of mixed nickel (II) oxide (NiO) and copper (II) oxides (CuO) have attracted considerable attention for both their catalytic properties and their electrochemical capacitance behaviors [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. For catalytic applications porous NiO-CuO materials have shown increased activation times over both the pure CuO and NiO [4][5][6].…”

“…Among the electrochemical methods, The EIS method is a powerful tool to study the electrode/electrolyte interface because it allows distinguishing various processes involved in the mechanism of hydrogenation/dehydrogenation reactions of metal hydride (MH) electrodes. [25][26][27] A very few investigations about the kinetic properties of the perovskite oxides using electrochemical impedance spectroscopy (EIS) method are presented. In our recently published article, 28 the LaGaO 3 perovskite oxide was reported as a potential negative material for Ni/MH battery.…”

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.
