Figure 3: EIS measurements of Li-suspension cells.
From: Sulphur-impregnated flow cathode to enable high-energy-density lithium flow batteries
(a) EIS data (dot symbols) and the fitting results (solid line) of 5S–12KB-MM and 5S–12KB Li-suspension cells after 1st, 5th and 10th discharge/charge cycles at C/9 (1C=1,675 mA g−1). (b) The equivalent circuit used to fit the EIS data shown in a. EIS-fitting results on (c) ohmic resistance, (d) interfacial resistance and (e) charge-transfer resistance for 5S–12KB-MM and 5S–12KB Li-suspension cells after 1st, 5th and 10th discharge/charge cycles. The EIS tests were replicated for three times.
