  • 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.

  • Translation and rotation are the two most fundamental forms of diffusion. Here, the authors provide evidence of the coupling between rotation and translation under confinement, and find that asymmetric rotations disrupt the order of molecular diffusion in zeolites, which can be applied to studies of selective separation.

  • Understanding the mechanism of ionic diffusion in superionic materials is crucial for their potential applications in solid-state batteries. Now liquid-like dynamics that break the Debye law of lattice dynamics have been demonstrated in a lithium electrolyte.

  • Effects from electrolytes on supercapacitor electrodes, especially pseudocapacitive materials, are important but often overlooked. Gogotsi and colleagues demonstrate strong influences from electrolyte solvents on charge-storage processes in a titanium carbide and identify a best-performing electrode/electrolyte couple for supercapacitors.

  • Superionic conductors present liquid-like ionic diffusivity with applications ranging from energy storage to thermoelectrics. A two-dimensional type I superionic conductor α-KAg3Se2 is now reported and should help to design other materials with tailored ionic conductivities and phase transitions.
