Dual mechanism of ion (de)intercalation and iodine redox towards advanced zinc batteries

We propose a dual-storage ion solution of Zn 2+ and I − with a cathode containing a mixture of NH 4 V 4 O 10 and porous activated carbon, exhibiting a dual mechanism of Zn 2+ (de)intercalation and iodine redox with adsorption–desorption.
