A protocol for gradient coating design zinc anodes for stable zinc ion batteries

In this protocol, we present a modified gradient coating strategy for zinc anodes. We describe steps for synthesizing electrodes, measuring electrochemistry, and assembling and testing batteries. The protocol can be applied for broadening design ideas of functional interface coating. For complete details on the use and execution of this protocol, please refer to Chen et al. (2023).1 [Display omitted] •Detailed protocol includes fabrication approaches for gradient-coated zinc anodes•Potential to advance zinc-ion battery applications•Gradient coating provides a design model for interface reconstruction of zinc anodes•Detailed sample preparation, instrument operation, and data analysis for precision Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
