In the last few years, renewable, inexpensive, biocompatible, and biodegradable wood and lignocellulose materials have triggered considerable research interest for application in various functional devices. However, there is still a lack of a new perspective to deeply understand the structure–property–function relationships of micro-/nanostructures and components of natural wood, so as to explore the potential of wood assembly of nano-energy materials with different dimensions. Herein, the recent progresses in the design and construction of f...
