How are positive ions stored in MnO2 cathode (positive electrode) in a supercapacitor? How do they overcome the repulsion?

Cations are intercalated/stored by surface redox reaction. As MnO2 electrode in a supercapacitor is a postive electrode, it should have attracted negative ions, but they store positive ions. How...
