Facile activation of commercial Ni foil as robust cathode for advanced rechargeable Ni-Zn battery

Nickel@Nickel Oxide Dendritic Architectures with Boosted Electrochemical Reactivity for Aqueous Nickel–Zinc Batteries

“…[13][14][15][16] Furthermore, aqueous electrolytes, with higher ionic conductivity, are conducive to a better rate performance of aqueous rechargeable batteries, giving them an edge over lithium ion batteries using organic electrolytes. [17][18][19][20][21] Nickel zinc (NiÀ Zn) batteries have the potential to be developed into one of the most reliable secondary alkaline batteries, due to their high output voltage platform of about 1.8 V (the output voltage platform of the other similar batteries is mostly lower than 1.2 V), high energy density, low cost, non-toxicity, and abundance of resources. [22][23][24][25][26] Although the Zn anodes own the high theoretical capacity (820 mAh g À 1 ) and low redox potential, the further development and utilization of NiÀ Zn batteries are largely restrained by the inevitable dendrite growth of Zn anodes and non-reversibility of Ni-based cathodes, which will lead to poor cycling stability.…”

Cost‐Effective Synthesis of Electrodeposited NiCo2O4 Nanosheets with Induced Oxygen Vacancies: A Highly Efficient Electrode Material for Hybrid Supercapacitors

“…Electrodeposition is a unique and well‐established process for the development of thin films, as it can control the surface morphology, thickness, uniformity, and is suitable for large‐area manufacturing with low capital investment [25,26] . Different types of current collectors/substrates have been used for the fabrication of electrode materials for supercapacitors such as ITO, Cu foil, Ni foil, Ni foam, carbon cloth, carbon paper etc [20,27–31] . However, the deposited metal oxides being poorly conductive and not meeting the commercial stability requirements further research is being focused on improving the electrochemical performance, stability and conductivity of the electrode materials.…”

Enhancement of Stability and Specific Charge Capacity of Alpha‐Ni(OH)2 by Mn(II) Isomorphic Substitution

“…In fact, the cost of extraction of a lithium carbonate ore is as high as US$5000 per ton, and a significant decrease in the reserves is being reported. Considering a growth of 5% per year in the amount extracted, there is an expectation that reserves will run out in about 65 years, leading to unprecedented technologic and economic crisis in the near future. Accordingly, the search for materials with suitable physico‐chemical characteristics to generate alternatives to batteries based on lithium becomes the uppermost importance.…”
