Abstract (en)
[origin: WO2021255487A2] The invention relates to a novel Zn-air rechargeable battery with charcoal/graphite cathode and dicarboxyl telechelic polyethylene glycol containing additive, e.g. PEG or POLOXAMER. The synthesized dicarboxyl telechelic PEGs were successfully applied to suppress the formation of dendritic and mossy deposits on the surface of the zinc electrode. The weight of the electrode did not change after the long-term test.
