Amorphous polyestersand polyethers with low Tg’s (−31 to −11 °C) were first prepared from xylose-based monomers (with varying lengths of fatty acid moiety) and 2,2′-(ethylenedioxy)diethanethiol (EDT) . Crosslinking by incorporation of a trifunctional monomer also produced a series of SPEs with ionic conductivities up to 2.2 × 10−5 S cm−1 at 60 °C and electrochemical stability up to 5.08 V, a significant improvement over previous xylose-derived materials. Furthermore, a series of copolymers bearing nucleoside moieties were prepared  \nto exploit the complementary base-pairing interaction of nucleobases. Flexible, transparent, and reprocessable SPE films were thus prepared with improved ionic conductivity (up to 1.5 × 10−4 S cm−1 at 60 °C), hydrolytic degradability, and potential self-healing capabilities.  \nKEYWORDS: sugars, xylose, fatty acids, nucleosides, base-pairing, self-healing, polymer electrolytes, lithium-ion conduction  \n■ INTRODUCTION  \nLithium-ion batteries (LIBs) are a continually evolving yet wellestablished technology essential for the transition of society to amore sustainable future. According to a 2019 Global Battery Alliance report for the World Economic Forum, it is predicted that the global demand for LIBs will have increased 14-fold from 184 GWh in 2018 to 2623 GWh by 2030.1 This will be primarily driven by our transition to electric vehicles and also by our continually increasing capacity to store renewable energy for the grid. However, the current use of liquid electrolyte components in LIBs poses a myriad of safety and performance issues. Various alternative electrolyte materials are being investigated to address these issues, among which polymer electrolytes are promising contenders. However, while many high-performance polymer electrolytes have been reported in the literature, the majority are derived from fossil fuel feedstocks and therefore do little to address the environmental and sustainability concerns surrounding petrochemically derived polymers.  \nTo this regard, there have been recent examples of polymer electrolytes featuring polysaccharides or carbohydrate-derived synthetic polymers, due to the merits of sugars as renewable polymer building blocks, such as their low cost, high abundance, high oxygen content, and high functionalization potential. For example, in 2022, Chen and co-workers exploited the high functionality of the natural polysaccharide chitosan to form cross-linked organogel polymer electrolyte networks with high room temperature ionic conductivity (1.1 × 10−3 S cm−1) and  \n© 2024 The Authors.
