Abstract

Flexible aqueous zinc-ion batteries(AZIBs)with air-recharging capability are a promising self-powered system applied in future wearable electronics.It is desired to develop high-capacity air-rechargeable AZ-IBs.Herein,we developed a flexible AZIB with air-recharging capability based on trinitrohexaazatrinaph-thylene(TNHATN)cathode and a ZnSO4 electrolyte.The flexible Zn//TNHATN battery exhibits high volu-metric energy density(21.36 mWh/cm3)and excellent mechanical flexibility.Impressing,the discharged flexible Zn//TNHATN battery can be chemical self-charged via the redox reaction between TNHATN cath-ode and O2 from the air.After oxidation in air for 15 h,such flexible Zn//TNHATN battery can deliver a high specific capacity of 320 mAh/g at 0.5 A/g,displaying excellent air-recharging capability.Notably,this flexible Zn//TNHATN battery also works well in chemical or/and galvanostatic charging mixed modes,showing reusability.This work provides a new insight for designing flexible aqueous self-powered sys-tems.
