Abstract Rechargeable polymer‐based solid‐state batteries with metallic lithium anodes and LiNi x Mn y Co 1− − O 2 (NMC)‐based cathodes promise safer high‐energy‐density storage solutions than existing lithium‐ion batteries, but have shown challenging to realize. The failure mechanisms that been suggested for these battery cells mostly related the use of a anode formation dendrites during cycling. Here, we approach issue using solid polymer electrolytes (SPEs) vs. NMC by employing range materials based on poly(ϵ‐caprolactone‐ co ‐trimethylene carbonate) (PCL‐PTMC) different salts under various cycling conditions. It is seen although ionic conductivity electrolyte can be improved exchanging salt, it does not immediately correlate better performance. However, increasing temperature improve ion transport kinetics lowers polarization cell full capacity achieved at an upper voltage cut‐off appropriate electrolyte. For electrolytes, limit demonstrated 4.4 V Li + /Li, NMC‐111 thereby possible provided limited below this limit.

Abstract Polyester thermoplastic elastomers are promising sustainable materials but their mechanical properties need improvement, in particular, attempts to increase strength often result compromised elasticity. Strong and tough known require complex polymer formulations together with control over cross‐linking or crystallinity, both of which challenge recycling. Here, the introduction transient strain‐stiffening approaches into fully amorphous structures show strengthening toughening while conserving recyclability. The new block polyester prepared by controlled polymerization methods using commercial monomers. polymers comprise a central poly(ɛ‐caprolactone‐ co ‐ɛ‐decalactone) flanked poly(cyclohexene oxide‐ alt ‐phthalate) blocks.

Abstract Aliphatic polyesters and polycarbonates are among the promising sustainable polymers, which exhibit unique degradability chain‐chain interactions owing to their heterofunctionality. However, monocomponent aliphatic usually suffer from inferior properties functionalities. By contrast, precisely modulated block copolymers composed of give rise materials with tailored performance. An efficient approach synthesize is ring‐opening (co)polymerization heterocycle monomers. Herein, this review presents monomer for formation sequence‐controlled polycarbonates. Available synthetic strategies, different monomers, combinations catalyst systems summarized.

Tetrahedral B(OR) (OH) − anions immobilized on polycarbonate segments provide hydrogen‐bonding chain crosslinking selective Li‐counterion conductivity, parameterized by Li‐ion transference numbers close unity ( t Li+ ~0.94). With 90 wt content flexible low glass transition temperature backbone, single‐ion conductors achieved conductivities 0.2 mS 30 °C. The work should inform future binder design for improving processability composites towards commercializing batteries, allow use in other cell configurations, such as lithium‐sulphur designs.
