Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Synthesis and Biodegradability of Copolymers of Ethylene Carbonate with Lactones [PDF]

Polymer Journal, 2000
The copolymers of ethylene carbonate (EC) with e-caprolactone (CL) or δ-valerolactone (VL) were synthesized using (C5Me5)2SmMe(THF) as initiator. We prepared EC/CL and EC/VL copolymers with a high molecular weight (Mn ≧; 140000) without decarboxylation from the EC unit. The EC/CL copolymers were obtained in a higher carbonate content (up to ca. 30 mol%)
