Atomic Insight into the Layered/Spinel Phase Transformation in Charged LiNi0.80Co0.15Al0.05O2 Cathode Particles

Autor: M. Stanley Whittingham, Hanlei Zhang, Eric A. Stach, Yiqing Huang, Khim Karki, Guangwen Zhou

Publikováno v: The Journal of Physical Chemistry C. 121:1421-1430

Layered LiNi0.80Co0.15Al0.05O2 (NCA) holds great promise as a potential cathode material for high energy density lithium ion batteries. However, its high capacity is heavily dependent on the stability of its layered structure, which suffers from a se
