Sun (a)(c) Keywords: Diffusion pathway; Energy barrier; Diffusion coefficient; Cooperative migration Abstract: a* Li diffusion pathways in Li.sub.4Ti.sub.5O.sub.12 and Li.sub.7Ti.sub.5O.sub.12 are obtained from ab initio calculations. a* Cooperative Li migration in Li.sub.7+[delta] Ti.sub.5O.sub.12 with very low energy barrier is proposed. a* Li diffusion is faster in lithiated state than in delithiated state is confirmed theoretically.
