Plenty of simulation studies have been widely implemented by researchers for LIBs: ranging from the cylindrical cell and pouch cells to the battery pack. Chunrong Zhao et al. probed the heat generation and cooling under various C rates for a battery module consisting of 71 18650 cylindrical cells . Via the developed thermalelectrochemical model, Naixing Yang et al. studied the unbalanced discharging and aging caused by the temperature difference between parallel-connected cells, and inhomogeneous discharging was highly aggravated by the temperature difference within different regions . Paolo Cicconi et al. proposed a systematic method for quick analysis of temperature for Li-ion battery package of lightweight commercial BEVs, and this method will contribute greatly to the fast design of BEVs . J. Sturm et al. models cylindrical 18650 LiNi 0.8 Mn 0.1 Co 0.1 O 2 (NMC811) || SiC cell under increasing charging rates from 0.2 C (5 hours) to highest 3 C (0.33 hours), exhibiting the generality of a theoretical model in simulating LIBs consisting of various electrode materials . For Li-S batteries, at this stage, to the best knowledge of the authors, there is no simulation probing effects of charing/discharging rates on Li-S batteries.
