本发明公开了一种锂离子电池的注液技术，涉及注液孔在极柱上的注液设计。注液时，利用固定架固定电池，采用橡胶圈和螺纹密封注液机注液嘴与极柱上的注液孔，通过抽真空的方式使电池内部实现负压将电解液注入电池内部。该技术解决了锂离子电池注液时定位难、注液效率低、密封效果差、电解液损失大、不易操作等问题。
Description
技术领域
本发明涉及一种锂离子电池的注液技术，尤其涉及一种锂离子电池注液定位性好、注液机注液嘴与极柱高效密封、注液效率高、电解液无浪费的注液技术。
背景技术
锂离子电池的注液技术是影响锂离子电池批量化高效生产、决定电池性能、控制成本的一个重要因素。目前，国内锂离子电池的注液技术多采用以下几种方式：第一种是将注液孔设计在盖板上，注液时，定位、密封注液机注液嘴和盖板注液孔，由于盖板注液孔孔径较小，这种设计增加了注液时电池定位的难度，影响了电池的高效生产；第二种是开口注液，即打开盖板注液，注液时不可避免的会产生电解液污染极耳，因此注液后需清洗极耳，操作过程非常复杂；第三种是对于大容量电池，采用手工注液，效率低，难实现规模化生产。
发明内容
针对上述现有技术中锂离子电池注液存在的问题，本发明提供了一种定位性好、注液效率高、密封效果好、电解液无浪费的锂离子电池注液孔设计及注液方法。
本发明要解决的技术问题所采取的技术方案是：
所述注液方法按以下过程进行：
(1)采用固定架固定电池。
(2)定位注液机注液嘴与电池，因盖板和电池壳体为一体，也即定位了注液机注液嘴与盖板极柱的注液孔。
(3)采用橡胶圈和螺纹共同密封注液机注液嘴和极柱注液孔。
(4)对电池抽真空。
(5)注液机内电解液在压差作用下压入电池内部。
(6)密封极柱注液孔。
本发明由于将注液孔设计在盖板极柱上，因此注液时，只需将注液机注液嘴与电池准确定位，便可实现注液机注液嘴与盖板注液孔的准确定位，从而减小了注液机注液嘴与电池注液孔定位困难的问题，提高了注液效率。注液时，采用了具备良好密封性橡胶圈和螺纹结合的设计，从而避免了注液时电解液的外漏。该种注液设计不仅解决了电池注液后密封性的问题，而且便于操作，减少了注液后电池不良品的出现几率，大大节约了生产成本。
