Embodiment Construction

[0049] The following is attached Figure 1-8 The application is described in further detail.

[0050] The embodiment of the application discloses a production process of an environment-friendly alkaline battery, comprising the following steps:

[0051] Step 1: Prepare the battery case 1, specifically through the following steps;

[0052] Step 101: Stretch the circular battery plate, and form the battery plate into a first green body with a preset inner diameter and a preset height, such as figure 1 shown;

[0053] Step 102, using a flaring die to expand the inner diameter of the upper section 103 and the lower section 105 of the first blank to form a second blank with a larger inner diameter of the upper section 103 and lower section 105 and a smaller inner diameter of the middle section 104, such as figure 2 shown;

[0054] Step 103, extruding the upper section 103 and the lower section 105 of the second green body toward the direction of the middle section 104 to obtain...

Abstract

The invention relates to an environment-friendly alkaline battery production process which comprises the following steps: an annular positive electrode end clamping groove is formed in the inner wall,close to a positive electrode end, of a battery shell, and an annular negative electrode end clamping groove is formed in the inner wall, close to a negative electrode end, of the battery shell; an annular elastic spacer is pressed into the positive electrode end cover, and after one end of the positive electrode end cover is coated with glue, the positive electrode end cover is arranged on the positive electrode end of the battery shell from the negative electrode end of the battery shell; the other end of the elastic spacer is clamped into the positive electrode end clamping groove; a positive electrode ring is pressed in, and a diaphragm cylinder and zinc paste are loaded into the battery shell; and the negative current collectoris inserted into the zinc paste, the negative end cover is pressed into the negative end of the battery shell, and a sealant is coatedbetween the battery shell and the negative end cover. The battery prepared by the process is good in sealing property and not easy to leak, and the environmental protection property is improved.

Description

technical field [0001] The present application relates to the technical field of alkaline batteries, in particular to an environment-friendly alkaline battery production process. Background technique [0002] Alkaline batteries are also known as alkaline dry batteries, alkaline zinc-manganese batteries, and alkaline-manganese batteries. They are the best-performing varieties in the zinc-manganese battery series. Suitable for large discharge and long-term use. The internal resistance of the battery is low, so the current generated is larger than that of ordinary carbon batteries. Since this type of battery does not contain mercury, it can be disposed of with domestic waste without intentional recycling. [0003] The Chinese invention patent with the authorized notification number CN101483253B discloses a highly stable and high-current alkaline battery, which is composed of a battery casing, a positive electrode ring, zinc paste and separator paper: the battery casing is a ni...
