Embodiment Construction

[0028] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0029] The structure of the battery cover used in one embodiment of the present invention is as follows Figure 4 and Figure 5 As shown, the battery cover is roughly in the shape of a cuboid, and a slot cover hole 13 is recessed on the upper surface of the battery cover toward the lower surface, and a terminal hole 1 is recessed on the lower surface of the battery cover toward the upper surface, and the terminal hole 1 is a blind hole. , and the blind end of the terminal hole is located in the slot cover hole 13 , that is, the blind end of the terminal hole 1 protrudes upward from the bottom surface of the slot cover hole 13 . During the battery production process, one of the steps is to combine the Figure 4 and 5 The battery cover of the shown structure is fixed on the battery body, that is, the capping step. When sealing t...

Abstract

The invention discloses a manufacturing method of a battery terminal and the battery terminal, wherein the method comprises the following steps: step A, extending a pole to a terminal hole which is arranged within a battery cover while a battery is covered, and then sealing the pole and the terminal hole into a whole by using a sealant, wherein the terminal hole is a blind hole which is concave from the lower surface of the battery cover to the upper surface thereof; step B, milling the terminal hole until exposing the head part of the pile; and step C, fixing a conductive terminal with the head part of the pole, and fixing the pole and the conductive terminal into a whole by using a coloring agent. The battery terminal manufactured by means of the method provided by the invention can effectively prevent the occurrence of acid leakage phenomenon.

Description

technical field [0001] The invention relates to the battery manufacturing industry, in particular to a method for manufacturing a battery terminal and the battery terminal. Background technique [0002] Batteries are widely used in many aspects of production and life due to their low price, reliable quality and long service life, for example, as the power source of electric vehicles. In practice, people have found that after the battery has been used for a period of time, white acidic substances tend to appear on the positive and negative conductive terminals of the battery. People call this phenomenon "acid crawling". Moreover, people also found that when the battery has the phenomenon of "acid creeping", the discharge capacity of the battery becomes smaller, the service life of the battery is also shortened, and other characteristics of the battery are also greatly improved than those of the battery without the phenomenon of "acid creeping". lowered. [0003] After analy...
