Protocol for modeling and simulating lithiation-induced stress in largely deformed spherical nanoparticles using COMSOL
STAR PROTOCOLS(2024)
摘要
Here, we present a finite element method -based scheme for solving coupled partial differential equations (PDEs) for the analysis of lithiation-induced stress in largely deformed spherical nanoparticles via the PDE module in COMSOL. We describe steps for software installation and setting PDEs, initial/boundary conditions, and mesh parameters. We then detail procedures for dividing the mesh and analyzing lithium trapping during electrochemical cycling. This protocol can also be extended to analyze a wide range of problems involving diffusion -induced stress. For complete details on the use and execution of this protocol, please refer to Li et al.1
