Abstract

The invention discloses a round zinc air battery with seal rings and without zinc lugs. The battery comprises a round multifunctional connecting ring and a battery outer frame; the bottom surface of the battery outer frame is provided with a diaphragm paper, a fuel zinc cake is placed on the diaphragm paper, and a zinc current collector is placed on the battery outer frame and is in conductive contact with the fuel zinc cake; a structure of upper and lower seal rings is added in the battery, the seal rings can realize good sealing property, and can avoid leakage of electrolyte for long time; when battery packs are superposed, a bottom ring of the multifunctional connecting ring is in surface contact with the zinc current collector 1 of the lower battery, thus, electric conduction is enhanced, and a lug structure is omitted skilfully, battery failure occurring possibly caused by fracture of the lugs is prevented, battery reliability is increased, technology is more simple, moreover, utilization rate of battery space is higher than before, and structure is more rational.

Description

technical field [0001] The invention relates to the field of zinc-air batteries, in particular to circular zinc-air batteries with sealing rings and no zinc tabs. Background technique [0002] Zinc-air batteries have attracted widespread attention due to their characteristics of large capacity, high specific energy, stable working voltage, environmental protection, and cheap materials. deteriorating, resulting in electrolyte leakage. Another problem is that the existing battery has a tab structure, which has poor reliability. If it is corroded or damaged by external force, the connection of the battery will be interrupted and the battery will not work. Therefore, more reasonable techniques are needed to avoid the above disadvantages. [0003] Existing zinc-air batteries are sealed by pressing flat rubber pads. This method is not a professional sealing method, and the sealing effect is poor. After a period of time, the seal will fail, resulting in partial leakage of the...
