Abstract

Biopolymer based electrolytes can overcome current performance limitations of lithium-ion batteries (LIBs). Biopolymers enable electrolytes with high ionic conductivities and wide electrochemical stability windows. While the biobased character of natural materials is claimed as an inherent advantage in meeting current environmental sustainability challenges, further research is required to quantify and compare their environmental impacts as electrolytes. The challenge is addressed by identifying the most promising biopolymer electrolytes for LIBs, measuring ionic conductivities and electrochemical stability windows, and quantifying environmental impacts using life cycle assessment. The environmental impacts of the cost to isolate cellulose derivatives, nanocelluloses, chitin/nanochitin, chitosan, lignin, agar, and silk are reported for climate change, acidification, freshwater ecotoxicity, marine eutrophication, human toxicity, and water use. Material criticality, circularity index, and material circularity indicator, emerging impact categories are prioritized to help integrate biopolymers into circular and sustainable materials. The electrochemical properties and environmental impacts of natural biopolymer membrane-liquid electrolyte pairs, gel electrolytes, and solid electrolytes are quantified and benchmarked against conventional fossil-based electrolytes, providing consistent and comparable electrochemical properties of the most relevant biopolymer electrolytes fabricated so far. This study highlights the significant functional and environmental benefits of biopolymer electrolytes and identifies the most electrochemically competitive biopolymer electrolytes in LIBs.

用于锂离子电池的天然生物聚合物电解质的环境可持续性
基于生物聚合物的电解质可以克服目前锂离子电池(LIBs)的性能限制。生物聚合物使电解质具有高离子电导率和宽电化学稳定窗口。虽然天然材料的生物基特性被认为是应对当前环境可持续性挑战的固有优势,但需要进一步的研究来量化和比较它们作为电解质对环境的影响。通过确定最有前途的锂离子电池生物聚合物电解质,测量离子电导率和电化学稳定性窗口,以及使用生命周期评估量化环境影响,解决了这一挑战。报告了分离纤维素衍生物、纳米纤维素、几丁质/纳米几丁质、壳聚糖、木质素、琼脂和丝绸的成本对气候变化、酸化、淡水生态毒性、海洋富营养化、人体毒性和水利用的环境影响。材料临界性、循环度指数和材料循环度指标,新兴的影响类别被优先考虑,以帮助将生物聚合物整合到循环和可持续材料中。对天然生物聚合物膜-液体电解质对、凝胶电解质和固体电解质的电化学性能和环境影响进行了量化,并与传统的化石基电解质进行了基准测试,提供了迄今为止制造的最相关的生物聚合物电解质的一致和可比的电化学性能。本研究强调了生物聚合物电解质的重要功能和环境效益,并确定了lib中最具电化学竞争力的生物聚合物电解质。
