Co-intercalation strategy of constructing partial cation substitution of ammonium vanadate {(NH4)2V6O16} for stable zinc ion storage

Simple synthesis strategy was adopted to prepare (NH 4 ) 2 V 6 O 16 with co-intercalation of Na + and H 2 O, which not only enhances the binding energy between V-O layers but also successfully improves the structural stability during the cyclic process.
