Improved cell kinetics enabled by PEB-1 compared with conventional PVDF binder. a Electrochemical impedance spectroscopy (EIS) for Li–S cells after cell assembly. b Cyclic voltammetry (CV) for Li–S cells after cell assembly. c, d Galvanostatic intermittent titration technique (GITT) for Li–S cells on the first discharge. e, f Potentiostatic discharge experiments for Li–S cells on the first discharge, after being equilibrated at 2.3 V for 6 h. The cell voltage was then lowered to either 2.0 V or 1.9 V to initiate the nucleation and growth of Li2S on the embedded current collector
