Description:
Operando magnetic susceptibility measurements on the Li x Ni 1 / 3 Mn 1 / 3 Co 1 / 3 O 2 cathode material during repetitive electrochemical cycling were performed, enabling a continuous and bulk sensitive monitoring of the charge compensation process. Upon charging and Li extraction down to the Li contents of x = 1/3, exclusively Ni undergoes oxidation in two consecutive steps, namely, Ni 2 + → Ni 3 + for x 〉 2/3 and Ni 3 + → Ni 4 + for 2/3 〉 x 〉 1/3 with a continuous transition in between. In the regime of low Li concentrations x
