Lithium anode-based Lithium-ion batteries (LIBs) have received much attention as next-generation batteries for their large energy density. However, commercialization of LIBs have been hindered by their dendrite formation, which significantly deteriorates battery life and performance. Inspired by this, we have developed a multiscale model to elucidate complex interactions between microscopic dendrite growth and macroscopic variables. Specifically, a first-principled kinetic Monte Carlo model describing the dendrite growth at the anode surface has been integrated with a macroscopic electrochemical model. The proposed multiscale model was able to successfully explain the effect of current density, cell voltage, and Li-ion concentration on dendrite growth and has been validated with experimental data. Furthermore, the proposed multiscale model can be extended to simulate charge-discharge cycles in the future studies and would pave the way to devise effective dendrite mitigation strategies. |
