Problems solved by technology

Cylindrical batteries or square batteries made of cylindrical battery cases or rectangular battery cases, due to shape constraints, cylindrical batteries are combined into a battery pack, especially when a large number of batteries are combined, the mechanical stability of the battery pack is poor, so that The working state of the battery pack combined with cylindrical batteries is extremely unstable, or the battery pack is disconnected, disconnected, or otherwise damaged due to bumps and vibrations, which affects the normal operation of the battery pack or fails to work at all or even explodes; Although there is no problem of poor mechanical stability when batteries are combined, the combination of square batteries will take up a lot of space. At the same time, the larger space occupied by the combination of square batteries also limits the number of single battery combinations, which in turn limits the application fields of batteries.

Embodiment 1

[0023] A method for manufacturing a regular hexagonal cylindrical battery case is manufactured according to the following steps:

[0024] In the first step, the stainless steel plate with a thickness of 0.2mm is cut into a square plate with a size of 6.0×2.5cm ( figure 1 a), and a regular hexagonal plate with a side length of 1.0cm, that is, the bottom shell 2 ( figure 2 );

[0025] The second step is to press the cut square plate into a regular hexagonal column with a side length of 1.0 cm and a height of 2.5 cm;

[0026] In the third step, the two sides of the cylinder are welded by laser to obtain the battery case 1 ( figure 1 b);

[0027] The fourth step is to weld one end of the shell 1 to the edge of the bottom shell 1 ( image 3 ).

Embodiment 2

[0029] A method for manufacturing a regular hexagonal cylindrical battery case is manufactured according to the following steps:

[0030] The first step is to cut the plate with a thickness of 1.0mm into a square plate with a size of 20×10cm ( figure 1 a), and a regular hexagonal plate with a side length of 3.5cm, that is, the bottom shell 2 ( figure 2 );

[0031] The second step is to press the cut square plate into a regular hexagonal column with a side length of 3.5cm and a height of 10cm;

[0032] In the third step, the two sides of the cylinder are welded by laser to obtain the battery case 1 ( figure 1 b);

[0033] The fourth step is to weld one end of the shell 1 to the edge of the bottom shell 1 ( image 3 ).

Embodiment 3

[0035] A method for manufacturing a regular hexagonal cylindrical battery case is manufactured according to the following steps:

[0036] In the first step, the nickel-plated steel plate with a thickness of 2.0mm is cut into a square plate with a size of 75×30cm ( figure 1 a), and a regular hexagonal plate with a side length of 12.5cm, that is, the bottom shell 2 ( figure 2 );

[0037] The second step is to press the cut square plate into a regular hexagonal column with a side length of 12.5cm and a height of 30cm;

[0038] In the third step, the two sides of the cylinder are welded by laser to obtain the battery case 1 ( figure 1 b);

[0039] The fourth step is to weld one end of the shell 1 to the edge of the bottom shell 1 ( image 3 ).

Abstract

The invention discloses a production method for a regular hexagonal prism-shaped battery case, which comprises the steps of: firstly, tailoring a thickness board to form a square board and a regular hexagon board, i.e. a bottom case; then, pressing the tailored square board into a regular hexagonal prism body according to the sizes of side length and height; thirdly, welding two sides of the prism body through laser to obtain the battery case; and fourthly, welding one end of the case and the edge of the bottom case, or pressing the board in one step through an abrasive tool for boards, or casting in one step through a regular hexagonal prism-shaped casting mould by utilizing stainless steel materials. The invention has the advantages of simple operation, and simple and convenient operation; the safety problems on impossible normal work or invalidation or explosion and the like of a battery pack, formed by a plurality of single batteries, under a jolting condition can be effectively solved; and the battery cases are suitable for the combination under various conditions, therefore, the space is saved, the normal use of the battery is guaranteed, and the service life of the battery pack is effectively prolonged.

Description

technical field [0001] The invention relates to the field of battery manufacturing, and more specifically relates to a method for manufacturing a regular hexagonal cylindrical battery case. Background technique [0002] At present, the battery cases used in the existing industry are generally cylindrical or rectangular battery cases. Cylindrical batteries or square batteries made of cylindrical battery cases or rectangular battery cases, due to shape constraints, cylindrical batteries are combined into a battery pack, especially when a large number of batteries are combined, the mechanical stability of the battery pack is poor, so that The working state of the battery pack combined with cylindrical batteries is extremely unstable, or the battery pack is disconnected, disconnected, or otherwise damaged due to bumps and vibrations, which affects the normal operation of the battery pack or fails to work at all or even explodes; Although there is no problem of poor mechanical s...
