 Aqueous-aqueous Xeon-ion batteries, Rasibs, have been receiving increased attention and are expected to be the next generation of energy storage systems. Metal Xeon anodes exhibit a limited service life and inferior reversibility owing to the issues of Xeon dendrites and side reactions. Researchers have attempted to design high-performance Xeon anodes by interfacial engineering, including surface modification and the addition of electrolyte additives.
