Wood-derived carbon anode for sodium-ion batteries
Abstract
Sodium-ion batteries (SIBs) are utilized as a promising alternative to commercial lithium-ion batteries (LIBs) where hard carbons (HCs) are anticipated to be the first commercially available anode material for SIBs. Among various hard carbon precursors, the wood accounts for more than 30% of the global land cover, making it one of the most abundant sources of biomass materials on the planet. In addition to superior renewability, sustainability and biodegradability, wood and its derivatives still possess some unique advantages such as anisotropic graded porous structure, good mechanical stability and biocompatibility. The purpose of this review is to present a comprehensive overview of the development of research on wood and wood-derived HCs anodes. The basic structural and chemical properties of wood and wood-derived materials are indeed reviewed, as is the performance of wood-derived HCs in SIBs to provide an in-depth comprehension and guidance for the preparation of high-performance wood-based SIBs.
