  • Solvation dynamics at picosecond timescales critically affect charge transport in aqueous systems, but conflicting values have been reported for organic electrolytes. Lifetimes on the order of 1 ns for mixtures of organic polymer and lithium salt exhibiting ultraslow dynamics of solvation shell break-up are now reported.

  • Failure caused by dendrite growth in rechargeable batteries with lithium metal anodes has prevented their widespread applicability. A microtomography study on lithium–polymer–lithium cells now reveals that at the early stage of dendrite formation dendritic structures lie within the electrode, underneath the polymer/electrode interface.

  • A polymer semiconductor/ionic-liquid nanocomposite exhibiting mixed conduction is reported. Using operando X-ray scattering, dynamic structural changes are observed on electrochemical charging, which enables efficient electronic transport.

  • Cationic polyelectrolytes have a broad range of applications, including membranes for fuel cells. Here, the authors report a family of cationic polyelectrolytes based on the highly modular cyclopropenium ion building block, which show high ionic conductivity and tunable physical properties.

  • The free-volume of a polymer is a key parameter in its ability to permit through transport of small molecules. Here, the authors develop a way of introducing different degrees of artificial free-volume to a polymer membrane, and thus tailor its penetrability for applications including biofuel purification.
