Mathematical Modeling of Multiple-Li-Dendrite Growth in Li-ion Battery Electrodes

Lithium dendrite growth in Li-ion batteries is one of the most dangerous phenomena because it can cause inner short circuits and thermal runaways. However, nucleation dendrites are difficult to predict their complex behaviors, which depend on several factors such as charging conditions electrode-design parameters. In this study, a comprehensive mathematical model has been developed for Li-deposition battery electrodes. The based Single Particle (to evaluate concentration fields) combined with dendrite-growth models electrochemical crystal theory. effect SEI thickness distribution, C-rate cut-off voltage tips have statistically evaluated, risk circuit discussed. study focuses effects SEI-thickness distribution timing breaking density formation.
