Description

Technical Field

[0001] This utility model mainly relates to the field of flexible aqueous zinc-ion batteries, specifically to a fast-charging flexible aqueous zinc-ion battery. Background Technology

[0002] Flexible aqueous zinc-ion batteries are a new type of secondary battery that combines flexible structure design, aqueous electrolyte and zinc-ion energy storage mechanism. They are safe, environmentally friendly and flexible, making them an ideal energy storage solution for future flexible electronic devices (such as wearable devices, foldable screens, medical sensors, etc.).

[0003] Its internal components mainly include an aqueous electrolyte, a zinc ion storage mechanism, and a flexible design.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] However, when zinc is deposited, the local current distribution is uneven, causing zinc to preferentially deposit at the protrusions, forming dendrites (tree-like protrusions). The electrodes inside the battery need to be replaced periodically. Since the electrodes are directly installed inside the battery, the entire battery can only be replaced, which increases the cost of replacing the battery.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

The cathode is metallic zinc Zn, which undergoes reversible dissolution discharge and deposition charging during charging and discharging: Zn2++2e−↔ZnZn2++2e−↔Zn. The flexible electrode body 304 as a whole adopts a flexible substrate such as carbon cloth, graphene, polymer-loaded active material, or is directly designed as a fiber / film structure or a flexible organic membrane with high ionic conductivity is introduced.

[0033] Furthermore, the side sealing structure 2 includes a sealing plate 201, and the number of sealing plates 201 is set to two. Connecting strips 202 are provided on both sides of the sealing plate 201. The sealing plate 201 is connected to the outer wall of the housing body 101.
