The effect of deposition temperature on nuclei size, nucleation density, and growth of deposited Zn metal is studied by ex-situ microscopy investigations. Lowering the deposition temperature leads to smaller nuclei, higher nucleation density, and smoother zinc growth, forming a dendrite-free electrode surface. Compact and smooth zinc deposits contribute to long-term stability. There is no change in overpotential for the cell at −10 °C for more than 400 h. Long-term Zn deposition in Zn/Cu cells achieves an average coulombic efficiency (CE) of 99.2 % in the last 50 cycles using ZnCl₂·10H₂O electrolyte. The performance of electrolytes is evaluated in zinc-ion batteries with (zinc hexacyanoferrate) ZnHCF cathodes.

The structural evolution of graphite during anion intercalation is also critically analyzed, with a focus on how interlayer spacing adjustments evolve during electrochemical cycling under solvent co-intercalation conditions. Furthermore, we present a systematic analysis of anion packing configurations within solvent-containing interlayers and their intrinsic link to theoretical capacity limits, offering new insights for optimizing intercalation efficiency.

Its operation relies on the redox reaction of cerium, specifically the reduction of cerium (IV) to cerium (III) at the interface between the Ta-gate and the 20GDC electrolyte. Under positive gate bias, the Ta gate electrode undergoes oxidation, while cerium is reduced, forming a conductive layer between the source and drain electrodes. Applying a negative gate bias reverses this effect. To confirm that resistivity changes originate from interface redox reactions, we conducted cyclic voltammetry at 403 K. The results demonstrate that peak current is inversely proportional to the scan rate, a characteristic of reaction at a surface. Additionally, we demonstrated that sputtering a TaO<sub>x</sub> blocking layer beneath the gate electrode suppresses resistive switching.
