A class of chloride-reinforced carbon nanofiber composites is fabricated by co-electrospinning and physical vapor deposition procedures, and is utilized as cathode substrate in a lithium–sulfur battery. The nonconductive halogenated salts can effectively confine lithium polysulfides in the 3D carbon matrix. Sulfide adsorption along with its diffusion near these chloride materials plays an important role on the reversibility of sulfur-based cathode.

Sulfur undergoes a multistep reaction during cycling. In discharge, sulfur is reduced to Li2S by accepting the Li-ions and electrons at cathode; in charge, a reversed reaction takes place. The electrolyte viscosity and polarization in cells influence the discharge and charge curves and therefore influence capacity and capacity fade of liquid-type lithium sulfur batteries.

The crucial step in the thermally activated delayed fluorescence (TADF) mechanism is the reverse intersystem crossing that converts triplet to singlet states. Here we show that this is mediated by a spin orbit charge transfer (CT) mechanism between the CT manifold and a local triplet state, and requires dynamic rocking about the D-A bond. This explains how molecular geometry and environment influences TADF and the photophysics of D-A-D molecules.
