Embodiment 1

[0043] The sealing of alkaline manganese battery in the present embodiment adopts above-mentioned assembly, uses PTFE film sealing, and specific sealing method is as follows:

[0044]Use 2 layers of PTFE film with a thickness of 0.1mm (the total thickness is 0.2mm). The sealing film is wrapped around the outer side of the sealing ring by using the battery crimping sealing compression method, and is sandwiched between the sealing ring of the alkaline manganese battery and the mouth of the steel shell. Between, seal, such as figure 1 As shown, the excess height of the sealing film after wrapping the sealing ring is 0.5 mm.

Embodiment 2

[0046] The sealing of the alkali-manganese battery in this embodiment adopts the above-mentioned components, and uses PTFE film sealing, and the specific preparation method is as follows:

[0047] Use 3 layers of PTFE films with a thickness of 0.4mm (the total thickness is 1.2mm). The sealing film is wrapped around the outer side of the sealing ring by the battery crimping sealing compression method, and is sandwiched between the sealing ring of the alkaline manganese battery and the steel shell mouth. Sealing is carried out during the interval, and the excess height after the sealing film wraps the sealing ring is 0.3mm.

Embodiment 3

[0049] The sealing of the alkali-manganese battery in this embodiment adopts the above-mentioned components, and uses PTFE film sealing, and the specific preparation method is as follows:

[0050] Use 4 layers of PTFE film with a thickness of 0.2mm (the total thickness is 0.8mm). The sealing film is wrapped around the outer side of the sealing ring by using the battery crimping sealing compression method, and is sandwiched between the sealing ring of the alkaline manganese battery and the mouth of the steel shell. Sealing is performed during the interval, and the excess height after the sealing film wraps the sealing ring is 0.2mm.

Abstract

The invention provides an alkaline manganese battery and a sealing method thereof. The alkaline manganese battery uses a non-polar material film as a sealing film, steel shell grains and sealing ringgrains are effectively blocked by utilizing a principle that strong polarity and non-polarity are incompatible, and alkaline electrolyte creepage and alkali leakage of the alkaline manganese battery are prevented. The problems of pollution, waste and high operation difficulty caused by using a sealing adhesive in the prior art are solved, resources are saved, and the production efficiency, the sealing reliability and the stability of the leakage-proof performance of the battery are improved.

Description

technical field [0001] The invention belongs to the field of alkaline manganese batteries, and in particular relates to an alkaline manganese battery and a sealing method thereof. Background technique [0002] Existing alkaline manganese batteries generally consist of a steel case, positive and negative electrodes of the battery, metal sheets, sealing rings, a negative rod connected to the negative end, and positive and negative fillers in the steel case. The thickness of each part of the steel shell is the same. In order to ensure the leakage resistance of the battery, a sealing ring is set between the steel shell and the metal sheet. A mechanical seal is used between the steel shell, the sealing ring and the metal, and the sealing ring forms a mechanical seal. deform and form a tight fit that prevents fluid from leaking out of the battery. In the prior art, the outer diameter of the battery is limited by the national standard size, and the thickness of the steel shell is ...
