Resumen:
Kinetic Monte Carlo (kMC) simulations are applied to simulate the insertion of Li ions into graphite. The present results show how the kinetics oflithium-ion intercalation in graphiterulesthe global process, making it difficult to reach thermodynamic equilibrium.The relatively slow rate of the events of insertion (deinsertion) of Li-ion into (from) the graphite are found to be responsiblefor the intercalation mechanism proposed by Daumas-Hérold. Thesearrangements can be be considered as frustrated, metastable structures, with a higher energy than that of the equilibrium state
