Moving Boundary Model For The Discharge Of A Licoo2 Electrode, Qi Zhang, Ralph E. White

Faculty Publications

A moving boundary model in a spherical LiCoO₂ particle is presented to account for the diffusion controlled phase transition in LiCoO₂ solid particles, and this model is incorporated into a porous electrode model for the LiCoO₂ electrode. The simulation results agree well with the experimental data of a LiCoO₂ electrode. A study of the flux distribution in the porous electrode shows that the phase transition phenomenon in the LiCoO₂particles has a significant effect on the flux distribution by changing the solid phase diffusion resistance in the particles.
