The Arrhenius equation was subsequently employed to derive the activation energy (Ea), as shown in Figure and Figures S17A and S17B for the 0.01 M BNC-containing electrolyte and the other two electrolytes, respectively. Here, the reciprocal of charge transfer resistance (1/Rct) is employed to represent the rate of SRR since polysulfides conversion involves charge transfer (Li-ion and anions). The Ea values at different DoD are summarized in Figure and Table , revealing that, for each electrolyte, Ea values at around 4.3 to 4.7%, 33.8 to 39.4%, and 59.5 to 66.1% are higher than their adjacent positions, signifying these DoD as crucial steps or rate-determining steps. In fact, these specified DoD ranges align with the two plateaus on the discharge voltage profile: 4.3 to 4.7% represents the initial elemental sulfur to long-chain polysulfide conversion, and 33.8 to 66.1% represents middle-chain to short-chain polysulfides conversion, which denotes more than half of the whole discharge capacity. Among the three electrolytes, 0.01 M BNC-containing electrolyte exhibits lower Ea values during the entire DoD, indicating the superior kinetics behavior induced by the BNC, especially in the 33.8 to 66.1% DoD range where the sluggish kinetics occurs associated with the liquid-solid and solid-solid conversions.
