“…As is well known, modern society is greatly dependent on portable electronic devices such as smart‐phones, laptops, electric vehicles (EVs), etc. In particular the demand on EVs equipped with self‐contained batteries will explode in the 21 st century due to the imperative of reducing carbon footprints . Lithium is here to stay due to its superior potential for energy storage, apart from being light in weight, electropositive, non‐toxic and broadly available.…”

We survey the past, present and future of polymers and macromolecular science, both in general and giving specific examples from our diverse array of research backgrounds within polymer science and technology. As befitting our common bond, we pay some attention to the role of IUPAC. In line with this being part of a Rosarium philosophorum, one might say we conclude that it is Citius, Altius, Fortius for polymers in the century ahead, by which we mean “faster engagement, higher value, stronger properties”, and one should also add “longer usage”. In this way our broad community will continue to build on the century that has passed since Hermann Staudinger launched macromolecular science.

“…To date, most of commercial Li batteries are based on organic electrolyte. The fluidity and low flash point of organic solution easily result in the leakage and volatilization of electrolyte as well as the burning of battery devices, which deviate from the tenet of pursuing higher security of Li battery in future development direction . Especially in Li metal batteries, Li dendrites are one of major risks for battery safety.…”

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.

have been found in preventing the pen etration of Li dendrites. [15][16][17] However, the excessive interfacial resistance and the complex processing art of inorganic SSEs limit their practical application. [18][19][20] Solid polymer electrolytes (SPEs), on the other hand, can offer good flexibility and stable contact between the electrodes and electrolytes. [20][21][22][23] Several types of polymer matrices have been developed, such as poly(ethyleneoxide) (PEO), [24][25][26] poly carbonate, [27][28][29] and polysiloxane. [30][31][32] SPEs are prepared by mixing polymer matrices with Li salts. PEO is the most popular and deeply studied polymer matrix, [33] and the ethylene oxide chain segments in PEO can dissolve Li salts as well as form complexes with Li + and dis sociated Li salts. [34] Li + is conducted by repeatedly carrying out a "decomplexa tion-recomplexation" process through the movement of chain segments in an amorphous polymer region. [35] The movement of chain segments in an amorphous polymer region is affected by the glass transition temperature (T g ) and crystallinity. Low T g and crystallinity are beneficial for the move ment of chain segments as well as the ionic conductivity. Due to the high crystallinity of PEO, PEObased SPEs have a low ionic conductivity (10 −8 -10 −7 S cm −1 ) at room temperature, which does not meet the requirement for ionic conductivity (>10 −4 S cm −1 at room temperature) of electrolytes with prom ising applications. [33,36,37] Many strategies, such as adding inorganic nanoparticles, [38][39][40] blending, [41] copolymerization, [42] and crosslinking [43][44][45] have been adopted to effectively sup press the crystallization of PEO and improve the ionic conduc tivity of PEObased SPEs. Coat et al. [46] reported the synthesis of poly(diethylene oxidealtoxymethylene) (P(2EOMO)) as a polymer matrix for SPE, which has higher T g than that of PEO in the electrolyte. They found the P(2EOMO)/LiTFSI electro lyte exhibits a slightly lower ionic conductivity due to higher T g , but much higher Li ion transference number can be obtained in P(2EOMO)/LiTFSI electrolyte (0.36) than that in PEO/ LiTFSI (0.19). So tailoring the main chain structure is the most feasible way to optimize the performance of SPEs.Recently, the strategy of in situ polymerizing SPEs in the batteries has attracted extensive attention due to the ability to construct stable ionic conduction networks inside the electrodes to reduce the interfacial resistance, the biggest challenge faced by most SSEs. Cui et al. [13] in situ prepared A series of copolymers are prepared via cationic ring-opening polymerization with 1,3-dioxolane (DOL) and trioxymethylene (TOM) as monomers. The crystallization behaviors of the copolymers can be suppressed by adjusting the ratio of DOL/TOM. With LiBF 4 as a source for a BF 3 initiator, copolymer electrolytes (CPEs) can be prepared in situ inside cells without needing nonelectrolyte catalysts or initiators. The ionic conductivities and Li + diffusion coefficients (D Li + ) of the CPEs inc...
