 The study proposes a weekly solvating electrolyte to reduce the solvating power of H2O in ZNI on batteries, which eliminates undesirable side reactions on the ZN anode and boosts desolvation kinetics of ZN2+, suppressing dendrite growth and structure aberration of the cathode. This leads to long-life full cells including ZN-NAV308.15 H2O, ZN-MNO2 and ZN-COFE, CN-6 cells, and practical rechargeable AA-type ZN-NVO cells with a capacity of 101.7 mAh and stability of 96.1% capacity retention after 30 cycles at 0.66C.
