None:
The Zn(solvents)x2+, with high desolvation energy barriers, leads to the formation of H+ and partial desolvated Zn2+ simultaneously intercalated into the MnO2 cathode. A single-atom Ni catalyst on nitrogen-doped carbon (SANi-NC) is introduced to achieve stepwise atom-level catalytic desolvation of Zn(H2O)x2+, which enables more insertion of Zn2+, thereby achieving high-performance Zn-MnO2 batteries.
