“…The catalytic activity of the metal towards HER material is also crucial; for instance, Hu et al's study on indium nucleation in acidic solutions using EQCM showed that while HER is negligible on glassy carbon substrates, it becomes significant on platinum substrates. [65] Other unwanted side reactions may arise from the reduction of the salt, additives, or other components in the electrolyte, as well as the corrosion of electrode materials, which can introduce undesirable ions into the system.…”

Herein the development and application of Electrochemical Quartz Crystal Microbalance (EQCM) sensing to study metal electroplating, especially for energy storage purposes, are reviewed. The roles of EQCM in describing electrode/electrolyte interface dynamics, such as the electric double-layer build-up, ionic/molecular adsorption, metal nucleation, and growth, are addressed. Modeling of the QCM sensor is introduced and its importance is emphasized. Challenges of metal electrode use, including side reactions and dendrite formation, along with their mitigation strategies are reviewed. Numerous factors affecting the electroplating processes, such as electrolyte composition, additives, temperature, and current density, and their influence on the electroplated metals’ mass, structural, and mechanical characteristics are discussed. Looking forward, the need for deeper fundamental understanding and advancing simulations of the QCM signal response as a result of electroplating metal nanostructures is stressed. Further development and integration of innovative EQCM-strategies will provide unique future means to fundamentally understand and optimize metal electroplating for energy storage and application alike.

“…The three-electron In 3+ /In redox reaction yields a high capacity of ∼700 mAh g –1 , which is close to that of transition metals (820–976 mAh g –1 , Figure d and Table S1) but markedly surpasses the tin anode (∼452 mAh g –1 ). Although there were some studies on the In metal plating by cyclic voltammetry techniques, − there has been no report to implement a trivalent indium metal battery. The possibility of using In 3+ as an innovative charge carrier for battery operation also remains elusive.…”

Aqueous batteries using multivalent metals hold great promise for energy storage due to their low cost, high energy, and high safety. Presently, divalent metals (zinc, iron, nickel, and manganese) prevail as the leading choice, which, however, suffer from low Coulombic efficiency or dendrite growth. In stark contrast, trivalent metals have received rare attention despite their capability to unlock unique redox reactions. Herein, we investigate trivalent indium as an innovative and high-performance metal anode for aqueous batteries. The three-electron In 3+ /In redox endows a high capacity of ∼700 mAh g −1 , on par with the Zn metal. Besides, indium exhibits a suitable redox potential (−0.34 V vs standard hydrogen electrode) and dendrite-free plating process, which renders an ultrahigh Coulombic efficiency of 99.3−99.8%. More surprisingly, it features an exceedingly low polarization of 1 mV in symmetrical cells, which is 1−2 orders of magnitude lower than any reported metals. The In-MnO 2 full cell also delivers impressive performance, with a cell voltage of ∼1.2 V, a high capacity of ∼330 mAh g −1 , and a long cycling time of 680 cycles. Our work exemplifies the efficacy of exploiting trivalent metals as an excellent metal anode, which provides an exciting direction for building high-performance aqueous batteries.

The negative reduction potential of gallium leads to the occurrence of the hydrogen evolution reaction (HER) during the process of gallium electrowinning. However, accurately measuring the partial current of the gallium electrodeposition reaction (GER) using the chronoamperometry (CA) test is not possible. To address this issue, a model capable of separating the partial current of the GER and HER from the total current was employed, and the CA curves were fitted at different potentials. This approach allowed the researchers to determine the relevant electrochemical parameters. The results indicated that the measured value of the current efficiency was in agreement with the fitted value, indicating the reliability of the model. The nondimensional forms of the partial contribution of GER were compared with the Scharifker−Hills model to determine the nucleation mechanism. The model showed that the GER transitions from instantaneous nucleation to progressive nucleation as the potential increases, which was further confirmed by the microscopic morphology at different electrodeposition times. In summary, this study offers a promising solution for accurately measuring the partial current of GER during gallium electrodeposition.
