What could be the reason for multi oxidation and reduction peaks(2or3) in CV for Co3O4? Some CO3O4 gives only one oxidation and reduction peak in CV?

I know that during oxidation & reduction Co oxidation state changes +2 to +3 to +4 vice versa. Explain why one peak in one case and why more peaks in other case even if material is same i.e Co3O4?
