Abstract Nanocellulose and its derivatives represent the most abundant biopolymers on Earth, offering a wide range of advantages, including versatility in preparation, customizable functional group incorporation, and compatibility with various materials. They open up new horizons in the development of various types of metal‐ion batteries (MIBs). This work concisely categorizes nanocellulose design strategies, including rational isolation, surface chemical enhancement, and effective physical treatments. Subsequently, an overview of recent advancements in utilizing nanocellulose and its derivatives to enhance the performance of MIBs, from lithium‐ion batteries (LIBs) to post lithium‐ion batteries (e.g., Na + , K +, Zn 2+ , Mg 2+ , Ca 2+ ) are provided. The pivotal roles of nanocellulose in electrode design, interface engineering, electrolyte modification, and binder optimization are highlighted. Lastly, the challenges and prospects of utilizing nanocellulose and its derivatives in MIBs are delved into. This work aims to comprehensively cover recent developments in nanocellulose surface modification strategies and illuminate their current applications in emerging MIBs with impressive energy and power densities.
