Recent progress on biomass-derived ecomaterials toward advanced rechargeable lithium batteries

Biomass materials are of great interest in high-energy rechargeable batteries due to their appealing merits of sustainability, environmental benefits, and more importantly, structural/compositional versatilities, abundant functional groups and many other unique physicochemical properties. In this perspective, we provide both overview and prospect on the contributions of biomass-derived ecomaterials to battery component engineering including binders, separators, polymer electrolytes, electrode hosts, and functional interlayers, and so forth toward high-stable lithium-ion batteries, lithium-sulfur batteries, lithium-oxygen batteries, and solid state lithium metal batteries. Furthermore, based on the multifunctionalities of bio-based materials, the design protocols for battery components with desired properties are highlighted. This perspective affords fresh inspiration on the rational designs of biomass-based materials for advanced lithium-based batteries, as well as the sustainable development of advanced energy storage devices.
