Li‐Intercalation Oxides: Atomic‐Scale Observation of LiFePO4 and LiCoO2 Dissolution Behavior in Aqueous Solutions (Adv. Funct. Mater. 45/2018)
Source abstract
Abstract
Dissolution behavior of cathode materials, LiCoO2 and LiFePO4, in aqueous electrolytes is investigated at an atomic level. In article number 1804564 Sung-Yoon Chung and co-workers use scanning transmission electron microscopy, in particular, to characterize an unusual cation occupancy in the tetrahedral interstices in LiCoO2 during Co dissolution. This atomic-scale observation provides a valuable contribution toward suppressing surface instability and thereby improving long-term stability of cathode materials in aqueous Li-ion batteries.
