Abstract
AbstractDifferent discharge rates and sulfur content have a great impact on battery performance. Therefore, this paper uses the finite element software comsol to simulate the lithium-sulfur battery model. Change the battery discharge rate and sulfur content parameters for simulation. The simulation results show that there are two voltage platforms in the low discharge rate simulation, while only one voltage platform appears in the high discharge rate; choosing the appropriate discharge rate is very important to exert the battery performance; higher sulfur content will increase the battery capacity accordingly, thereby affecting Battery discharge time. Through this simulation, it has great guiding significance for the actual selection of the appropriate discharge rate and sulfur content of the lithium-sulfur battery. It laid the foundation for accelerating the commercialization of lithium-sulfur batteries.KeywordsLithium-sulfur batteryModel simulationSulfur contentDischarge rate
