Investigation of pristine Li1.2Ni0.13Mn0.56Co0.13O2 by advanced TEM

Layered Li‐transition metal (TM) oxides are very promising materials for new Li ion battery cathodes. Compounds with an increased content of Li and Mn are particularly interesting because they exhibit a high capacity of 200‐300 mAhg −1 even after an initial drop in capacity during the first charging cycle.[1] The structure of such compounds and their capacity degradation over multiple cycles is not fully understood due to the complexity of the …
