Two-dimensional MXenes offer promising potential for energy storage but are limited by rapid oxidation and restacking issues. Here, the authors enhance MXene stability through polyvinylpyrrolidone-catechol functionalization, achieving superior performance in sodium-ion batteries with a composite anode, demonstrating significant improvements in capacity and ionic conductivity, and paving the way for advanced energy storage solutions.
