摘要：
Origin and Hysteresis of Lithium Compositional Spatiodynamics within Battery Primary Particles J. Lim, Y. Li, D. H. Alsem, H. So, S. C. Lee, P. Bai, D. A. Cogswell, X. Liu, N. Jin, Y.-s. Yu, N. J. Salmon, D. A. Shapiro, M. Z. Bazant, T. Tyliszczak, W. C. Chueh Science 2016, 353, 566. 采用原位X射线成像技术研究锂嵌入／脱出LixFePO4过程，发现提高锂嵌入速度可抑制颗粒内部相分离和降低机械张力，有利于提高材料的循环性能，但锂脱出过程则情况相反.
