Developing clean and sustainable energies as alternatives to fossil fuels is in strong demand within modern society. The oxygen evolution reaction (OER) is the efficiency-limiting process in plenty of key renewable energy systems, such as electrochemical water splitting and rechargeable metal-air batteries. In this regard, ongoing efforts have been devoted to seeking high-performance electrocatalysts for enhanced energy conversion efficiency. Apart from traditional precious-metal-based catalysts, nickel-based compounds are the most promising earth-abundant OER catalysts, attracting ever-increasing interest due to high activity and stability. In this review, the recent progress on nickel-based oxide and (oxy)hydroxide composites for water oxidation catalysis in terms of materials design/synthesis and electrochemical performance is summarized. Some underlying mechanisms to profoundly understand the catalytic active sites are also highlighted. In addition, the future research trends and perspectives on the development of Ni-based OER electrocatalysts are discussed.

“…With the same strategy, it is possible to separate the metallic Li anode from the cathode side with a water‐impermeable separator. Zhang et al built an ARLB (or, in a sense, half aqueous) by utilizing the aqueous redox of Ni(OH)2/NiOOH separated from the nonaqueous Li/Li + anode redox by a thin glass–ceramic film of Li 1+ x + y Al x Ti 2− x Si y P 3− y O 12 . Gaining the high specific capacities of both anode and cathode, the resulting cell could deliver a high specific capacity of over 250 mAh g −1 .…”

research, aqueous electrolytes were occasionally employed for the investigation of cathode materials instead of the conventional nonaqueous electrolytes. [9,10] It was discussed that the simplicity of an aqueous electrolyte provides a better opportunity for the fundamental studies of the process of intercalation/deintercalation of Li-ions as opposed to the nonaqueous electrolytes. For instance, although the formation of solid electrolyte interphase (SEI) is of utmost importance for the cyclability of LIB, the significant role of the electrolyte does not allow to exclusively study the electrochemical behavior of the electrode material under consideration. The current research has specifically targeted the development of ARLBs, but in practice, most of the recent papers have followed the same line of research in investigating a limited range of cathode and anode materials in the same aqueous electrolytes. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] A possible reason is that the key advantage of ARLBs was low cost, and thus, the focus was limited to a few inexpensive materials (e.g., lithium salts). Aqueous electrolytes are definitely excellent choices for the fundamental studies of electrode materials, but the practical development of ARLBs needs overcoming the key obstacles rather than finding more cathode materials.In any case, aqueous electrolytes were occasionally used during the 2000s by various research groups, but there was no vivid plan for the development of ARLBs. These works have been extensively reviewed before, [29][30][31][32][33] and it is not aimed to repeat the general works on aqueous electrolytes here. During the recent years, new opportunities have been introduced, which can extend the stable potential window of aqueous electrolyte to the range of 3-4 V. Upon this advancement, aqueous electrolytes can fairly compete with the conventional nonaqueous electrolytes for the fabrication of cheaper and safer LIBs. On the other hand, novel designs such as self-healing [34] or flexible [16,35,36] ARLBs have paved the path for new practical potentials of aqueous electrolytes. The present paper specifically focuses on the recent advancements and attempts to foster the strategy of research to shed light on the pathway of this emerging area of research. Two factors are directly responsible for achieving a high energy density, the specific capacity, and the cell voltage. Since the former is not massively controlled by the electrolyte and the specific capacity of most electroactive Owing to the high voltage of lithium-ion batteries (LIBs), the dominating electrolyte is non-aqueous. The idea of an aqueous rechargeable lithium battery (ARLB) dates back to 1994, but it had attracted little attention due to the narrow stable potential window of aqueous electrolytes, which results in low energy density. However, aqueous electrolytes were employed during the 2000s for the fundamental studies of electrode materials in the absence of side reactions such as the decomposition of organic spec...

explored for increasing the energy density of ARBs: one is to use electrode materials with higher specific capacities and the other is to improve the output voltages of ARBs. [7-9] Applying high capacity materials, such as sulfur and zinc metal, as electrode materials can significantly improve the energy density of ARBs to an anticipated level, but the energy density of ARBs is still relatively limited for two main reasons. [10-15] First, the specific capacity of most electrode materials is not much different from that used for organic systems. [8] Second, the standard working voltage of these batteries is less than 2 V, which is restricted by the narrow electrochemical stability window of a single-phase solution. Using a cathode material with a higher potential, and a anode material with lower potential can effectively utilize the voltage window of a single electrolyte to a greater extent, [16,17] but the increment of energy density is still restricted due to the limited voltage window of a single electrolyte. Therefore, in order to fully improve the energy density of ARBs, an extended voltage window of electrolytes is highly desired to match the electrode materials with higher or lower working potential. So far, there are mainly four ways to widen the voltage stability window of aqueous electrolytes. First, an artificial solid electrolyte interface (SEI) is introduced to prevent the negative electrodes (such as Li metal, Mg metal and graphite) with extremely low working potential from contact with aqueous electrolytes directly. [18-23] This approach could promise ARBs with ultra-high voltage and ultra-high energy density, but requires dense ceramic membrane that can conduct Li + and effectively block water molecules. The synthesis of ceramic membrane is complex and its price is high. Second, the voltage stability window can be widened by using super-concentrated aqueous electrolytes, which include "'water-in-salt"' electrolytes (3.0 V), "'water-in-bisalt"' electrolytes (3.1 V) and hydrate-melt electrolytes (3.8 V), etc. [10,24-30] This method opens up a new horizon for high voltage, high energy density ARBs, but the used organic lithium salts are more expensive and less suitable for large-scale applications. [31-34] Third, the addition of additives can form an interface similar to SEI on the surface of the material, which can also effectively widen the voltage stability window of aqueous electrolyte. [35-38] Fourth, electrolytes with different pH values, mainly acid electrolytes and alkaline electrolytes, are assembled to form a hybrid electrolyte system. This method is relatively simple, and the electrolyte salt used is Aqueous rechargeable batteries (ARBs) offer advantages in terms of safety, environmental friendliness and cost over their non-aqueous counterparts. However, the narrow electrochemical stability window of water inherently limits the output voltage and energy density of ARBs. Here, a system with an aqueous hybrid electrolyte containing a Zn anode in alkaline solution and LiMn 2 O 4 cathode in neu...
