Researchers observe major source of aging in Li-ion cathode materials
Green Car Congress

Due to the Li + -H + exchange during the charging process it degrades to ABBCCA (right). The researchers were interested in elucidating electrochemical processes in high-capacity Li-rich cathode materials: (x)Li 2 MnO 3 *(1-x)LiMO 2 (“M” is a transition metal such as manganese, chromium or iron).
