Description

Technical Field

[0001] The present invention relates to the field of energy technology, and in particular to a battery processing method capable of supplying power at both ends simultaneously, or supplying power at one end and charging at the other end, and more particularly to a battery processing method provided with conductive pins at both ends. Background Art

[0002] Currently, lithium manganese pin-type batteries are widely used in various small electronic products due to their small size and light weight. They are connected to LED lights to form lighting lamps, and are used in electronic products such as night fishing floats, luminous arrow tails, and darts. However, the following disadvantages occur during use:

[0003] First, the existing lithium manganese pin-type batteries only have the function of supplying power at one end. For some electrical appliances such as fishing floats and fishing lights that require two ends to emit light or two ends to emit different colors of light, two batteries have to be used or another power supply point has to be made by welding. This increases the cost, occupies a large space, has a large weight, and is inconvenient.

[0004] Second, the existing lithium manganese pin-type batteries only have the function of supplying power, resulting in being discarded after the battery power is exhausted, becoming disposable consumables, having a relatively high use cost, and causing environmental pollution, which is not conducive to environmental protection.

[0005] In summary, the existing batteries cannot meet the usage requirements of consumers for simultaneous power supply or simultaneous power supply and charging during use, and need to be improved. Summary of the Invention

[0006] In order to overcome the disadvantages of short battery life cycle, a large amount of waste, environmental pollution, and non-conduciveness to environmental protection in the prior art, the purpose of the present invention is to provide a battery processing method provided with conductive pins at both ends, which can improve the battery life cycle and meet the power supply and charging usage requirements of the battery.

[0007] To achieve the above object, the technical solution of the present invention is as follows:

[0048] For the convenience of those skilled in the art to understand, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present invention.

[0049] Embodiment 1.

[0050] Please refer to Figures 1-1 to 2-2 , a battery processing method with conductive pins provided at both ends of the present invention, including an outer shell 1, a sealing plug 2, a negative conductive rod 3, a conductive medium 7 and a battery core 8. The outer shell 1 has openings at both ends. The processing method is as follows:

[0051] The battery core 8 is sleeved outside the negative conductive rod 3 and abuts against the negative conductive rod 3. The outer shell 1 wraps the battery core 8. Both ends of the negative conductive rod 3 in the length direction protrude from both ends of the outer shell 1 in the length direction to form a first semi-finished product 100;

[0052] The sealing plug 2 is inserted into one open end of the outer shell 1, and then rolled to form a groove 11. The groove 11 is located at the intersection of the outer shell 1 and the sealing plug 2;

[0053] Inject the conductive medium 7;

[0054] The sealing plug 2 is inserted into the other open end of the outer shell 1, and then rolled to form a groove 11 at the intersection of the outer shell 1 and the sealing plug 2.

[0055] Specifically, in this embodiment, the outer shell 1 is cut from an aluminum tube. The outer shell 1 has open ends at both ends. The length specification of the negative conductive rod 3 is greater than that of the outer shell 1. The negative conductive rod 3 is located inside the outer shell 1. The battery core 8 is located between the outer shell 1 and the negative conductive rod 3. Both ends of the negative conductive rod 3 in the length direction protrude from both ends of the outer shell 1 in the length direction to form a first semi-finished product 100. The number of sealing plugs 2 is two. One sealing plug 2 is inserted into one open end of the outer shell 1 of the first semi-finished product 100. Then, the intersection of the outer shell 1 and the sealing plug 2 is rolled to form a groove 11. The setting of the groove 11 improves the sealing effect. Then, the conductive medium 7, which is electrolyte, is injected through the other opening, and vacuum is pumped to make the electrolyte fully immerse. Then, the other sealing plug 2 is inserted into the other end of the outer shell 1 for sealing, and the intersection of the outer shell 1 and the sealing plug 2 is rolled to form a groove 11, that is, the open end is further sealed to improve the sealing effect, and the processing of the battery is completed.

[0056] By providing the outer shell 1 with open ends at both ends, both ends of the negative conductive rod 3 in the length direction protrude from the two open ends of the outer shell 1. The battery core 8 is arranged between the outer shell 1 and the negative conductive rod 3. The battery core 8 abuts against the outer shell 1 and the negative conductive rod 3 respectively. The sealing plugs 2 seal the two open ends of the outer shell 1 to complete the battery processing. The negative conductive rod 3 protruding from the open end of the outer shell 1 forms a conductive pin, achieving the purpose that both ends of the battery can be used, that is, meeting the demand of simultaneous power supply at both ends, or power supply at one end and charging at the other end.

Each positive electrode ring body 6 is in contact with the inner side wall of the outer shell 1. The positive electrode ring body 6 and the outer shell 1 are assembled into the second semi-finished product 200. Then, the second semi-finished product 200 is placed in an external oven. The baking temperature of the second semi-finished product 200 is 108 °C, the baking time is 12 hours, and the vacuum is -0.1 Pa. In this baking stage, nitrogen is put in after vacuuming, and the nitrogen is replaced every 2 hours. Or in this baking stage, dry gas is put in after vacuuming, and the dry gas is replaced every 2 hours;

[0064] Synchronously, the negative electrode conducting rod 3 and the separator layer 5 are placed in another oven. The set temperature of this oven is 85 °C, and the baking time is 120 minutes. The negative electrode conducting rod 3 and the separator layer 5 are dried;

[0065] Then, the second semi-finished product 200 and the dried negative electrode conducting rod 3 and separator layer 5 are transferred to an external drying oven for assembly. The process parameters of the drying oven are set to -50 °C. First, the metallic lithium strip 41 is wound around the preset part of the negative electrode conducting rod 3.
