I am trying to understand Cyclic voltammetry behavior of commercial LiMn1/3Ni1/3Co1/3O2 cathodes obtained from a industrial source. However, contrary to the typical capacitive curves reported in literature for synthesized materials, I have intersection of oxidative and reductive parts during the CV. Has anyone come across similar situation like this?

The below two CV profiles are repetitions to see if its the same.

Conditions:

Cathodic half cell in coin cell set up, scan rate 0.1 mV/sec

MNC cathode/ 1M LiPF6 in EC:DEC (50uL) polypropylene separator/Li metal
