Description

氟碳介质在动力锂离子电池领域中的应用
技术领域
本发明涉及变压器领域，尤其涉及氟碳介质在动力锂离子电池领域中的应用。
背景技术
近年来，由于人们环保意识的提高和政府对电动汽车的大力补贴，电动汽车的产销出现了爆发式的增长。电动汽车的推广，消除了汽车尾气对环境的污染。目前电动汽车普遍使用锂离子电池作为储能装置，锂离子电池在充、放电过程中会产生大量的热量，如果不能有效地将这些产生的热量散发到环境中，轻则会影响锂离子电池的效率和使用寿命，重则会引起锂离子电池的燃烧和爆炸，对人身安全产生危险。目前通用的锂离子电池组的散热方法是通过电风扇的强制对流，特斯拉的电池组采用了在18650锂离子表面绕上细细的铜管，通过铜管内介质的流动带走产生的热量。但这些方法都是通过非接触的方式进行的，其散热效果有限，所以电动汽车的安全事故还时有发生。所以研究锂离子电池高效散热方法，提高锂离子电池的热管理效率，以提高锂离子电池汽车的行驶性能和安全性能，是电动汽车目前需要解决的一个迫切课题。
发明内容
本发明的目的在于提供一种安全、降温效果好，稳定的蒸发冷却变压器氟碳介质。
为实现上述目的，本发明提供一种氟碳介质C3H4F4O或C6F12或C6F12O或C4H4F6O或C5H3F9O或C6H4F10O在动力锂离子电池领域的用途。
进一步，将氟碳介质C3H4F4O或C6F12或C6F12O或C4H4F6O或C5H3F9O或C6H4F10O装入密封容器中，使C3H4F4O或C6F12或C6F12O或C4H4F6O或C5H3F9O或C6H4F10O浸没锂离子电池即可。
本发明的氟碳介质具有不燃、不爆、无毒、对环境友好等的优异性能。其基本性能见表1：
表1：氟碳冷却介质（FCM）的基本性能表
锂离子电池组的结果如图1所示。将锂离子电池组置入图1所示的槽内，再在槽内灌满氟碳冷却介质，让锂离子电池直接浸没在该氟碳冷却介质中。槽的盖板是带有密封材料的金属板，可以自由开关，以便于使用过程中对锂离子电池的维修和保养，但由于盖板带有密封材料，所以整个槽是一个密封性能良好的一个体系，以防止介质的泄漏和挥发。槽的四周有很多的散热片，以增加其散热面积，提高其散热性能。由于槽内氟碳介质的粘度很小，有很好的流动性，所以通过介质在槽内的运动及槽体的大量散热片，将锂电池的热量散发到环境中。
现有技术的硅油，则粘度大，流动差，有一定的燃烧性；如果是水，则容易短路，如果是有机物质，容易燃烧。本发明提供的氟碳冷却介质C3H4F4O或C6F12或C6F12O或C4H4F6O或C5H3F9O或C6H4F10O具有不燃、不爆、无毒、对环境友好等的优异性能，用于锂离子电池具有非常好的防爆效果。
附图说明
图1是锂离子电池组采用本发明的氟碳冷却介质的散热系统示意图。
具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。实施例中未注明具体技术或条件者，按照本领域内的文献所描述的技术或条件或者按照产品说明书进行。所用试剂或仪器未注明生产厂商者，均为可以通过市购获得的常规产品。
实施例1：
将18650电池在氟碳介质中做针刺实验，结果如表2所示：
表2：氟碳介质中，18650电池的针刺实验结果
对比实验：
暴露在空气中，对18650电池做针刺试验，结果在10秒钟内发生剧烈爆炸。
说明本发明的氟碳介质C3H4F4O或C6F12或C6F12O或C4H4F6O或C5H3F9O或C6H4F10O非常安全，不会发生爆炸。
实施例2：
使用装置如图一所示，对在介质内的电池组进行快速充、放电。用温度传感器检测电池组表面的温度。将电池组浸没在一个充满冷却介质的容器中，容器的四周有很多的散热片，提供介质的散热作用，容器顶部用带有密封材料的盖子盖紧，以避免介质的蒸发损失。其中1为氟碳散热介质，2为散热片，3为电池组，4为密封盖。
对比试验，将相同电池组，暴露在空气中进行快速充、放电使用，并坚持过程中的电池组表面温度变化。结果显示电池组表面温度如表3所示。
表3快速充、放电过程中，电池组表面温度对比表
从表3可以看出，采用氟碳介质C3H4F4O或C6F12或C6F12O或C4H4F6O或C5H3F9O或C6H4F10O用于电池降温的降温效果好，比暴露在空气中的温度降低很多，降温明显。说明氟碳介质C3H4F4O或C6F12或C6F12O或C4H4F6O或C5H3F9O或C6H4F10O用于动力锂离子电池具有明显的降温效果。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在不脱离本发明的原理和宗旨的情况下在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
