Understanding rate and capacity limitations in li–s batteries based on solid-state sulfur conversion in confinement

HIGHLIGHTS

• What: The authors aim to deepen the understanding of the capacity and rate limitation using a variety of structure-sensitive and electrochemical techniques such as operando small angle neutron scattering (SANS) operando X-ray diffraction (XRD) electrochemical impedance spectroscopy (EIS) and galvanostatic charge/discharge. Some early works argued that the confinement in pores is the main reason for the solid-state conversion28-30. Using electrochemical measurements, the authors explore two factors that could potentially limit the cathode`s rate performance and capacity . The authors compare full-cell EIS/GITT data of two cells with two different nanoporous . . .
