Problems solved by technology

[0003] However, in the prior art, in the process of preparing zinc-ion batteries, an aqueous solution is used as the electrolyte. During the cycle, zinc ions will be deposited on the zinc electrodes to passivate the zinc electrodes. At the same time, the formed zinc dendrites will penetrate the separator and cause battery damage. Short circuit; In addition, the water electrolyte is prone to hydrogen evolution, resulting in battery flatulence

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to an organic zinc ion secondary battery. Background technique [0002] At present, the existing zinc-ion battery is a secondary ion battery that can be recharged and discharged repeatedly. It has the characteristics of safety, environmental protection and low cost, and has very high potential application value in many fields such as electronics, communication, and energy. [0003] However, in the prior art, in the process of preparing zinc-ion batteries, an aqueous solution is used as the electrolyte. During the cycle, zinc ions will be deposited on the zinc electrodes to passivate the zinc electrodes. At the same time, the formed zinc dendrites will penetrate the separator and cause battery damage. Short circuit; In addition, the water electrolyte is prone to hydrogen evolution, resulting in battery flatulence. Contents of the invention [0004] The object of the present inv...
