A two-mechanism and multiscale compatible approach for solid state electrolytes of (Li-ion) batteries

摘要

All-solid-state batteries are claimed to be the next-generation battery system, in view of their safety accompanied by high energy densities. A new advanced, multiscale compatible, and fully three-dimensional model for solid electrolytes is presented in this note. The response of the electrolyte is profoundly studied theoretically and numerically, analyzing the equilibrium and steady-state behaviors, the limiting factors, as well as the most relevant constitutive parameters according to the sensitivity analysis of the model, the novel model is finally validated in accordance with experimental results.
