Abstract

Lithium metal stands out as an advanced anode material for next-generation rechargeable high-energy-density batteries. Nevertheless, the non-uniform behavior of Li plating/stripping causes severe dendrite growth and volume expansion, inducing rapid lifespan decay and even safety hazards. Introducing a Li host with a three-dimensional (3D) structure and interconnecting pores has been proven effective for solving these issues. In this contribution, natural wood, which possesses an exquisite 3D interconnected hierarchical porous structure, is employed as a Li host. The wood host facilitates homogenization of the electric field intensity near the Li anode, thereby regulating the homogeneity during Li plating/stripping. As demonstrated in Li|Cu half cells, the wood host enables 66 cycles with a coulombic efficiency retention of 80%, surpassing the mere 25 cycles achievable without the host. Furthermore, the wood/Li composite anode exhibits reduced polarizations and extended cycling lifespans in both Li|LFP and Li|S full coin cells. Leveraging the unique characteristics of the natural wood structure, an all-wood-based Li|S full coin cell is also assembled. This study not only illuminates the promise of wood as a material for optimizing Li anode performance, but also offers valuable insights for the design of structures for materials used in rechargeable batteries.

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
