Outline of Final Research Achievements

Understanding of the reaction hierarchies of lithium-ion batteries (LiB) is essential background knowledge to improve their performance. Because the reactions in these devices are complicated and proceed in a nonequilibrium state, the kinetic factors and degradation mechanisms that govern them are not yet fully characterized.　　Phase transitions in active materials are accompanied by lithium insertion and extraction. The crystal structure during charge-discharge has generally been investigated through static measurements, in which thermodynamically stable states are characterized. In addition, the diffusion path of lithium ions has also been analyzed. Under real battery operating conditions, however, the crystal phase dynamically changes during lithium extraction/insertion. The dynamic phase transition is one of the critical parameters determining rate capability because the charge-discharge process of LIBs proceeds under nonequilibrium conditions.
