“…Currently, resources are meeting 65% of global energy demands. Fossil fuels release harmful greenhouse gases like CO 2 , which cause global warming and other environmental problems. − To combat the depletion of fossil fuels and the rise in CO 2 emissions, at least 10 terawatt-hour (TWh) of renewable energy must be produced by 2050. This energy can come from sources like solar, wind, hydroelectricity, biomass, ocean thermal, and sea waves/tides. − …”

The study focused on the fabrication of nickel, cobalt, and their bimetallic oxide via a facile electrodeposition approach over the surface of conducting glass has been reported here. Fabricated electrodes have been employed as binder-free and effective anode materials toward oxygen evolution reactions (OER) in electrochemical water splitting at high pH. Nickel and cobalt oxides showed overpotential values of 520 mV and 536 mV at the current density of 10 mAcm −2 with charge transfer resistances of 170 and 195 Ω. For bimetallic oxides (NiCoO@FTO), the overpotential depressed up to 460 mV and lower charge transfer value of 80 Ω. Additionally, double-layer capacitance also boosted for the bimetallic oxide with a value of 199 μF as compared to monometallic nickel oxide (106 μF) and cobalt oxide (120 μF). Multimetal oxides of Ni−Co showed the best performance, which was further supported with larger electrochemical surface area. This facile approach toward the electrode fabrication could be a charming alternate to replace the Ru-and Ir-based expensive materials for OER in electrochemical water splitting.

The practical implementation of such a battery design would require extensive research and development of a battery chemistry that aims for higher energy density by utilizing reactions that involve electron transfer reaction through redox potentials. Electrochemical loop, known as the chloride-bromide loop, which enhances the kinetics and reversibility of the bromide/bromate anion, (BrO⁻₃) electrode reaction. The exact combined reversibility capacity of 1150 mAh g− 1, leads to more energy that can be stored in a given mass of the battery. Electron transfer bromine to deliver a high specific capacity measures the amount of charge and high specific capacity indicates a high charge-storage capability. The successful validation of in bromide full batteries and acid-alkaline decoupling batteries. This technology is promising for high-energy-density aqueous batteries and essential in the field of energy storage, as it can potentially lead to safer, more efficient, and longer-lasting battery solutions and may find applications in various fields, including electric vehicles, portable electronic materials, greater energy density and efficiency are crucial.

The battery chemistry aiming for high energy density calls for the redox couples that embrace multi-electron transfer with high redox potential. Here we report a twelve-electron transfer iodine electrode based on the conversion between iodide and iodate in aqueous electrolyte, which is six times than that of the conventional iodide/iodine redox couple. This is enabled by interhalogen chemistry between iodine (in the electrode) and bromide (in the acidic electrolyte), which provides an electrochemical-chemical loop (the bromide-iodate loop) that accelerates the kinetics and reversibility of the iodide/iodate electrode reaction. In the deliberately designed aqueous electrolyte, the twelve-electron iodine electrode delivers a high specific capacity of 1200 mAh g−1 with good reversibility, corresponding to a high energy density of 1357 Wh kg−1. The proposed iodine electrode is substantially promising for the design of future high energy density aqueous batteries, as validated by the zinc-iodine full battery and the acid-alkaline decoupling battery.
