The rapid development of electrochemical energy storage (EES) devices requires multi‐functional materials. Nickel (Ni)‐based materials are regarded as promising candidates for EES devices owing to their unique performance characteristics, low cost, abundance, and environmental friendliness. This review summarizes the scientific advances of Ni‐based materials for rechargeable batteries since 2018, including lithium‐ion/sodium‐ion/potassium‐ion batteries (LIBs/SIBs/PIBs), lithium–sulfur batteries (LSBs), Ni‐based aqueous batteries, and metal–air batteries (MABs). The Ni‐based materials are mainly classified by the various roles of anodes and cathodes for LIBs and SIBs, cathode hosts and separators for LSBs, cathodes for Ni‐based aqueous batteries, and catalysts for MABs, focusing on the relationship between the compositions, structures, and electrochemical performance. Finally, the challenges and prospects of Ni‐based materials for rechargeable batteries are briefly discussed.

“…[31,32] W4f spectra ( Figure 3e) showed W 4f 5/2 (37.5 eV) and W 4f 7/2 (35.4 eV), attributing to W 6+ . [33,34] The deconvoluted O1s spectra (Figure 3f) indicated the presence of metal-oxygen bonds (FeO, NiO, WO) and hydroxyl groups (OH). [35][36][37] We compared the valence states of Ni and Fe in NiFe LDH-POM with those in the reported NiFe LDH and NiFeV LDH.…”

Considering the intermittency of typical renewable and environment-friendly energy resources, such as wind, tide, and solar energy, it is encouraging to explore all-weather utilization ones. [1] Electrochemical water splitting for hydrogen and oxygen production may overcome the challenge as an ideal sustainable system for the future. [2] Unfortunately, the high activation barriers and sluggish kinetics of hydrogen and oxygen evolution reactions (HER and OER) hindered their further applications. [3] Since HER and OER must be operated in the same electrolyte for overall water splitting, efficient bifunctional electrocatalysts, which can prevent cross-contamination, materials incompatibilities, and possible catalyst poisoning, are attracting everincreasing attentions. [4] Earth-abundant transition metal layered double hydroxides (LDHs) have been recognized as promising electrocatalysts

“…[25] Due to abundance, costeffectiveness and enhanced protection, zinc-air batteries have gained much attention amongst the other metal-air batteries. [26]- [28] The high charging rate, low equivalent weight of Zinc, less possibility of thermal runaway, minimal requirement of specific manufacturing environment, less toxicity and high stability without corrosion in alkaline and aqueous medium are the significant advantages of Zinc-air cell. [29,30] Also, various other competing batteries are found in energy research like sodium ion battery or lithium sulphur battery.…”

“…[43][44][45] They have the capabilities to enhance the conductivity by improving the structure. [28,46,47] The best ORR catalysts are those with a higher surface water content and unique surface planes. [48] In comparison to the commercial Pt/C with onset potential of −0.5 V and E 1/2 of −0.87 V (shown in Figure S2), CV was conducted in 0.1 M O 2 saturated KOH from +1 to −1V (vs. Ag/AgCl) to access the catalytic ORR functionality at a scan rate of 20 mVs −1 as shown in Figure 5a.…”

The felicitous electrolyte with advance electrodes (cathode and anode) results in the development of an improved and efficacious battery/fuel cell. Perovskite based zinc‐air batteries with biological gel electrolyte prove to outperform the aqueous batteries. In this research, a zinc‐air battery was developed using a novel biocompatible electrolyte, Guar‐gum employing LaMnO3 (LMO) perovskite as a bi‐functional electro‐catalyst. The performance of the developed perovskite catalyst in guar‐gum electrolyte was obtained and compared with the performance of the material in both polymer gel (polyvinyl alcohol‐KOH) and aqueous medium. The bi‐functional catalyst shows enhanced catalytic activity, endurance and durability in alkaline medium with an open circuit voltage of 1.40 V, power density of 9.77 mW cm−2 at the current density of 11.12 mA cm−2 and a specific capacity of 2624 mAh g−1 comparatively competent with respect to the PVA‐based battery with the specific capacitance of 753 mAh g−1. Also, the rechargeable LMO zinc‐air battery exhibited excellent cycling stability at a current density of 10 mA cm−2. Thus, the results obtained proved the competent performance of the guar‐gum electrolyte compared to the previous developed polymer electrolyte. This is how the combination of LMO in the guar‐gum electrolyte is seen to be successful for commercial use in metal‐air batteries and fuel cells.
