1. Nanocellulose: From natural polymers to high-performance functional materials Nanocellulose (Nanocellulose) is a nanoscale material prepared from natural cellulose through mechanical dissociation, chemical modification (such as TEMPO oxidation) or enzymatic treatment. It is mainly divided into: CNF (Cellulose Nanofiber) nanocellulose fiber CNC (Cellulose) Nanocrystal) Nanocellulose crystal is essentially a linear polysaccharide material with a highly ordered structure, showing significant performance transitions at the nanoscale: ▶ Core structure advantages Structural features Corresponding performance Nanoscale diameter (5–50 nm) High specific surface area (>200 m²/g) High crystalline area ratio Excellent mechanical strength (modulus up to 140 GPa) Rich hydroxyl/carboxyl groups Easy surface functionalization Three-dimensional network structure Excellent film-forming properties and

1. Industrial background: The wave of new energy promotes the upgrading of material systems. Driven by the global 'double carbon goals' and the transformation of energy structure, the new energy industry continues to grow at a rapid pace. Core areas represented by lithium-ion batteries and energy storage systems have put forward higher requirements for material performance: · Higher energy density · Longer cycle life · Higher safety · Lower environmental load Traditional material systems (such as PVDF binders, organic solvent systems, etc.) are gradually exposing performance and environmental bottlenecks. In this context, nanocellulose (Nanocellulose) is becoming an important candidate for a new generation of battery materials due to its greenness, renewable nature and structural designability. �� The industry trend is very clear: the application focus of nanocellulose is rapidly shifting from traditional fields to new energy material systems. 2. Material Nature: Analysis of the Structural Advantages of Nanocellulose Nanocellulose mainly includes: · CNF (Cell
