摘      要：Flexible and all-solid-state zinc-air batteries(ZABs)are highly useful and also in demand due to their theoretical high energy densities and special *** limitation in their performance arises due to their catalyst-coated cathode electrodes in terms of catalytic activity and stability as well as *** this paper,a novel and environmentally friendly activation strategy is developed to activate the carbon cloth(CC)for the *** activated CC serves as a catalyst-free air cathode with high conductivity,excellent mechanical strength,and flexibility,in addition to low *** strategy is performed by simply electro-oxidizing and electroreducing CC under ultrahigh direct current(DC)voltage in a diluted NH4Cl aqueous *** is found that the electro-oxidation not only results in the formation of a graphene-like exfoliated carbon layer on the surface of CC but also induces the incorporation of oxygen-containing groups and doping of nitrogen and chloride *** the electroreduction,theπ-conjugated carbon network of CC is partially restored,leading to the recovery of *** an electroactivated CC shows excellent oxygen reduction reaction *** aqueous flexibility and all-solid-state ZABs are assembled using such an electroactivated CC cathode without any catalyst *** ZABs can achieve good durability and deliver high peak power density and an energy density as high as 690 Wh kg^(−1),demonstrating the excellent potential of this electroactivated CC in practical devices.
