The lithiation and delithiation of a silicon battery anode is modeled using the material point method (MPM). The main challenges in modelling this process using the MPM is to simulate stress dependent diffusion coupled with concentration dependent stress within a material that undergoes large deformations. MPM is chosen as the numerical method of choice because of its ability to handle large deformations. A method for modelling diffusion within MPM is described. A stress dependent model for… CONTINUE READING
