The solid polymer electrolyte (SPE) as a key battery component promises advances in solid-state lithium (Li) metal batteries (SSLMBs). Biomass, with a naturally derived structure design, composition and physical/chemical properties, exhibits advantages over the traditionally synthesized polymers in SPE. Biomass-integrated SPEs are, therefore, expected to address the key issues of SPE (e.g., low ionic conductivity, poor mechanical properties, and environmental concerns), promoting the development of safe, sustainable, and energy-dense SSLMBs. However, reviews on such perspectives are presently limited. This review summarizes the applications of renewable biomass in SPEs, from the partial to the complete substitution of synthetic polymers. The sources and properties of biomass are considered, providing a new understanding of the roles of biomass as an additive, the skeleton, and the main material of SPEs. Moreover, the correlation between biomass and the improved performances of SPEs (e.g., ion conduction and mechanical properties) is discussed. The design protocols for SPEs with desirable properties are also highlighted based on the multifunctionalities of biomass, proposing potential revolutionary strategies. This perspective provides enlightenment for the rational design of biomass-based SPEs, accelerating the sustainable development of advanced energy storage devices.

设计用于安全和高能量密度锂金属电池的生物质集成固体聚合物电解质

固态聚合物电解质 (SPE) 作为关键电池组件有望推动固态锂 (Li) 金属电池 (SSLMB) 的发展。生物质具有天然衍生的结构设计、组成和物理/化学性质，与 SPE 中传统合成的聚合物相比具有优势。因此，生物质集成 SPE 有望解决 SPE 的关键问题（例如、低离子电导率、差的机械性能和环境问题），促进安全、可持续和高能量密度的 SSLMBs 的发展。然而，目前对这些观点的评论是有限的。本综述总结了可再生生物质在 SPE 中的应用，从合成聚合物的部分替代到完全替代。考虑了生物质的来源和特性，使人们对生物质作为 SPE 的添加剂、骨架和主要材料的作用有了新的认识。此外，生物量与 SPE 性能改进之间的相关性（例如，离子传导和机械性能）进行了讨论。基于生物质的多功能性，还强调了具有理想特性的 SPE 的设计方案，提出了潜在的革命性策略。这一观点为生物质基SPEs的合理设计提供了启示，加速了先进储能装置的可持续发展。
