Visualization of anisotropic-isotropic phase transformation dynamics in battery electrode particles
Autor: Jiajun Wang, Yu-chen Karen Chen-Wiegart, Christopher Eng, Qun Shen, Jun Wang
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-7 (2016)
Spatiotemporal phase evolution during transformations impacts materials performance in many systems. Here the authors use lithium iron phosphate particles inside a custom-designed battery to characterize in three dimensions the two-phase configuratio
