[0001] 本发明涉及锂电池技术领域， 特别涉及一种热收缩塑料薄膜外壳一 次性锂离子电池及其制造方法。 [0001] The present invention relates to the field of lithium battery technology, and in particular, to a heat-shrinkable plastic film casing primary lithium ion battery and a method of manufacturing the same.
背景技术 Background technique
[0002] 目前， 市场上出现的电子烟产品存在的瓶颈突出体现在： 第一， 锂 离子电池的体积和容量的问题。 譬如， 电池的容量大了， 体积也大了。 电 池容量大， 具有可增加电子烟抽吸口数的优点， 但是电池的体积随着容量 增大而增大， 失去了仿真烟的真实性,在外观上与真实的香烟相比较严重失 真。 第二， 电子烟的电池目前市面上主要采用可反复充电的锂离子电池， 在一次性电子烟中， 也同样采用可反复充电的锂离子电池。 对于可充电锂 离子电池在设计中要考虑到反复充电的寿命、 安全性等等因素， 所以制造 材料成本增大， 工艺相对复杂， 造成电子烟的价格昂贵。 另外， 现有的电子 烟的电池壳体部分都比较厚， 那么同等型号规格的电芯体积变小了， 电池 容量也就相应小， 抽吸烟的口数也就减少了。 [0002] At present, the bottlenecks in the electronic cigarette products appearing on the market are prominently reflected in: First, the problem of the volume and capacity of lithium ion batteries. For example, the battery has a large capacity and a large volume. The battery has a large capacity and has the advantage of increasing the number of e-cigarette suction ports. However, the volume of the battery increases with the increase of the capacity, and the authenticity of the simulated cigarette is lost, and the appearance is seriously distorted compared with the actual cigarette. Second, the electronic cigarette battery currently uses a rechargeable lithium-ion battery on the market. In disposable electronic cigarettes, a rechargeable lithium-ion battery is also used. For rechargeable lithium-ion batteries, the lifespan, safety and other factors of repeated charging should be considered in the design, so the cost of manufacturing materials is increased, the process is relatively complicated, and the price of electronic cigarettes is expensive. In addition, the battery casing parts of the existing electronic cigarettes are relatively thick, so that the battery of the same model size becomes smaller, the battery capacity is correspondingly small, and the number of smoking cigarettes is reduced.
发明内容 Summary of the invention
[0003] 鉴于上述问题， 本发明的目的在于提供一种可提高锂离子电池电芯 的容量增大， 体积不变， 成本低、 实用， 使用安全， 及更适合自动化组装 的热收缩塑料薄膜外壳一次性锂离子电池及其制造方法。 In view of the above problems, an object of the present invention is to provide a heat-shrinkable plastic film casing which can increase the capacity of a lithium ion battery cell, has a constant volume, is low in cost, is practical, is safe to use, and is more suitable for automated assembly.

[0004] 为实现上述目的， 本发明提供的一种热收缩塑料薄膜外壳一次性锂 离子电池， 其中， 包括锂离子电池电芯、 在锂离子电池电芯两端分别设有 的端子定位片和盖板、 从锂离子电池电芯内部引出并贯穿端子定位片且延 伸至端子定位片外的正极导针和负极导针， 及在锂离子电池电芯上设有的 热收缩塑料薄膜外壳。 端子定位片上设置有注液排气孔。 注液排气孔上设 置有密封注液排气孔的塞针。 正极转接导针和负板导针， 及注液排气孔设 置于端子定位片的同一端面上。
[0005] 在一些实施方式中， 热收缩塑料薄膜外壳的壁厚是 0.08mm及以下。 由此， 与现有电池外壳壁厚大于 0.12mm以上外壳相比，壳体壁厚薄了。原所 有结构的同等型号规格的电芯体积都比现有结构的同等型号规格的电芯体 积的小了 10%以上。 [0004] In order to achieve the above object, the present invention provides a heat-shrinkable plastic film outer casing disposable lithium ion battery, which comprises a lithium ion battery cell, a terminal positioning piece respectively disposed at two ends of the lithium ion battery cell, and The cover plate, the positive and negative guide pins which are drawn from the inside of the lithium ion battery cell and penetrate the terminal positioning piece and extend to the outside of the terminal positioning piece, and the heat shrinkable plastic film case provided on the lithium ion battery cell. A liquid injection vent hole is provided on the terminal positioning piece. A plug for sealing the injection vent hole is provided on the injection vent hole. The positive transfer pin and the negative plate guide pin, and the liquid injection vent hole are disposed on the same end surface of the terminal locating piece. [0005] In some embodiments, the heat shrinkable plastic film outer casing has a wall thickness of 0.08 mm or less. Thereby, the wall thickness of the casing is thinner than that of the conventional battery casing having a wall thickness of more than 0.12 mm. The volume of the same type of battery of all the original structures is 10% smaller than the volume of the same type of battery of the existing structure.
[0006] 在一些实施方式中， 锂离子电池电芯两端的端子定位片和盖板上分 别设置有密封胶层。 由此， 锂离子电池电芯、 端子定位片和盖板是整体密 封的。 In some embodiments, a sealant layer is disposed on the terminal locating tab and the cover plate at both ends of the lithium ion battery cell. Thus, the lithium ion battery cell, the terminal locating tab and the cover are integrally sealed.
[0007] 本发明的另一目的是提供一种热收缩塑料薄膜外壳一次性锂离子电 池的制造方法， 具体歩骤如下： Another object of the present invention is to provide a method for manufacturing a disposable lithium ion battery of a heat shrinkable plastic film casing, and the specific steps are as follows:
第一歩， 将端子定位片套入正导针和负导针上， 之后与盖板分别安装于锂 离子电池芯两端， 之后整体装入热收缩塑料薄膜外壳内； Firstly, the terminal positioning piece is sleeved on the positive guiding pin and the negative guiding pin, and then mounted on the two ends of the lithium ion battery core respectively, and then integrated into the heat shrinkable plastic film outer casing;
第二歩， 通过加热热收缩塑料薄膜外壳使锂离子电池电芯、 端子定位片和 盖板紧密收缩成锂离子电池电芯； Secondly, the lithium ion battery cell, the terminal positioning piece and the cover plate are tightly shrunk into a lithium ion battery cell by heating the heat shrinkable plastic film casing;
第三歩， 在注液排气孔中间插入塞针； Third, insert a needle in the middle of the injection vent;

第五歩， 拔掉经过密封胶密封后锂离子电池电芯上的塞针， 之后整体放入 烤箱内进行烘烤； Fifth, unplug the plug on the lithium ion battery cell sealed by the sealant, and then put it into the oven for baking;
第六歩， 把烤干的锂离子电池电芯取出放入真空含浸缸内泡在电解液中， 其中电解液从注液排气孔流入锂离子电池电芯内， 待锂离子电池电芯内的 锂离子电芯完全浸透电解液， 才从真空含浸缸内取出； The sixth step, the dried lithium ion battery cell is taken out into a vacuum impregnation cylinder and bubbled in the electrolyte, wherein the electrolyte flows from the liquid injection vent hole into the lithium ion battery cell, and is to be used in the lithium ion battery cell. The lithium ion battery is completely saturated with the electrolyte before being taken out of the vacuum impregnation cylinder;
第七歩， 把套有储气袋的排气管插入端子定位片的注液排气孔中， 进行化 成充电； In the seventh step, the exhaust pipe with the air bag is inserted into the liquid injection vent hole of the terminal positioning piece to be charged and charged;
第八歩， 待充电完成后， 在干燥房中拔掉排气管， 之后立即插入塞针， 再 用密封胶把塞针周边的缝隙密封。 Eighth, after the charging is completed, unplug the exhaust pipe in the dry room, then insert the plug immediately, and seal the gap around the plug with the sealant.
[0008] 本发明的有益效果是具有可提高锂离子电池电芯的容量增大， 体积
不变， 成本低、 实用， 及使用安全的技术效果。 由于锂离子电池电芯上设 有的热收缩塑料薄膜外壳， 这种薄膜类型的电池外壳比较薄， 可以增加电 芯的直径。 如此一来， 可以把电芯的直径做到极限值， 不但可以增加电芯 的容量， 电子烟的抽吸口数也相应同歩增加了， 而且电芯组装时也很方便 插入。 实现了提高锂离子电池电芯的容量增大， 体积不变， 成本低、 实用 的目的。 另外， 端子定位片上设置有注液排气孔， 注液排气孔上设置有密 封注液排气孔的塞针， 及使用了抗压强度较小的塑料薄膜做外売， 在电池 出现异常时， 会产生气体， 气体压力过大会把塞针从注液排气孔中顶出或 者把塑料薄膜壳体冲破泄放气体。 利用塞针和塑料薄膜这二个方案更好地 防止气体因不及时排泄而引起意外事故的发生。 实现了使用更加安全的目 的。 又由于正极导针和负板导针， 及注液排气孔设置于端子定位片的同一 端面上， 有利于在组装电子烟时把这一端面组装在电子烟灯帽端。 倘若一 旦有电池气体从注液排气孔中泄出时， 气体能通过灯帽气孔排到烟管外， 能有效地防止电池气体在吸烟时吸入口中。 进一歩地更实现了使用安全的 目的。 又由于从锂离子电池电芯内部引出并贯穿端子定位片且延伸至端子 定位片外的正极导针和负极导针， 那么这一部分的正极导针和负板导针， 在进行电子烟组装时这导针更适合自动化接插件组装。 [0008] The beneficial effects of the invention are that the capacity of the lithium ion battery cell can be increased, and the volume is increased. Constant, low cost, practical, and safe to use technical effects. Due to the heat-shrinkable plastic film casing provided on the lithium ion battery cell, the cell type of the film type is relatively thin, and the diameter of the cell can be increased. In this way, the diameter of the battery core can be made to a limit value, not only the capacity of the battery core can be increased, but also the number of suction ports of the electronic cigarette is increased correspondingly, and the battery core is also easy to insert when assembled. The utility model has the advantages that the capacity of the lithium ion battery cell is increased, the volume is constant, the cost is low, and the utility is practical. In addition, the terminal positioning piece is provided with a liquid-filling vent hole, the liquid-filling vent hole is provided with a plug for sealing the liquid-filling vent hole, and a plastic film having a small compressive strength is used as a sputum, and the battery is abnormal. At this time, gas is generated, and the gas pressure is excessively pushed out of the injection vent hole or the plastic film casing is broken through the vent gas. The two solutions of the needle and the plastic film are used to better prevent accidents caused by the gas being discharged in time. Achieve a safer use. Moreover, since the positive and negative guide pins and the liquid injection vent are disposed on the same end surface of the terminal locating piece, it is advantageous to assemble the end surface at the end of the electronic cigarette lamp when assembling the electronic cigarette. If the battery gas is discharged from the injection vent hole, the gas can be discharged to the outside of the pipe through the vent hole of the lamp cap, which can effectively prevent the battery gas from being sucked into the mouth during smoking. Further, the purpose of using security is further realized. And because the positive and negative guide pins are taken out from the inside of the lithium ion battery cell and penetrate the terminal positioning piece and extend outside the terminal positioning piece, the positive and negative guide pins of this part are used for electronic cigarette assembly. This guide pin is more suitable for automated connector assembly.
