技术领域
本发明涉及软包铝离子电池、软包锂离子电池封装材料领域,特别涉及一种高耐腐蚀多涂氟层型软包铝离子电池铝塑膜。
背景技术
软包铝电池是未来电池发展的主要方向,如何实现软包铝离子电池的可靠封装,及保证、稳定和提高软包铝离子电池的性能是相关电池厂家十分关心的重要问题。电池性能的好坏不仅与电池内部的电解质、隔膜、正负极材料有关,还与软包铝离子电池的封装铝塑膜有十分密切的联系。当前的软包铝塑膜主要应用于软包锂离子电池的封装,而铝离子电池最快可实现1min充电,循环次数达7500次以上,耐腐蚀环境要求更严苛复杂,当前铝塑膜难以满足其封装要求。
软包铝离子电池最后是通过铝塑膜封装形成成品电池,封装铝塑膜质量的好坏对成品电池的各项性能均具有重要影响,若铝塑膜的质量不过关,电池中若出现铝箔腐蚀、穿孔等现象时,软包铝离子电池的容量将变小、电压降增大,电池充放电和循环寿命均呈现快速下降,严重时甚至会导致电池快速失效,因此软包铝离子电池封装铝塑膜材料一般要求具有极高的耐腐蚀性能,因此如何研制高耐腐蚀性能且兼顾热封性能、阻隔性能及各项指标均较优异的铝离子电池封装铝塑膜对该类型电池的长期稳定运行均具有十分重要的意义。
发明内容

作为本发明的一种优选方案,所述铝箔层的厚度为30-100μm。作为本发明的一种优选方案,所述涂氟层为四氟乙烯、三氟氯乙烯与乙烯基醚、乙烯基酯一种或几种共聚,厚度为10-40μm。
一种高耐腐蚀多涂氟层型软包铝离子电池铝塑膜及其制造方法,其特征在于,包括以下步骤:
(1)铝箔层3的双面涂覆含氟性粘结材料,形成双涂氟面的铝箔材料,常温净化环境下保存备用;
(2)在双涂氟铝箔的一面通过熔融加热与聚丙烯进行层压热复合,得到具有热封性的聚丙烯/铝箔复合材料;
(3)在聚丙烯/铝箔的铝箔涂氟耐腐蚀层面涂覆氟涂料层,形成铝材料为阻隔层,铝外层为双氟保护层,铝内层为氟保护层和热封层的多层复合材料。
(4)将该铝塑膜进行微波固化和或加热固化和或40℃-90℃干燥环境温度下熟化120h,得到成品铝塑膜。
采用上述技术方案后,本发明的有益效果是:首先,该铝塑膜通过涂氟粘结层可有效阻止电池内部电解液对铝塑膜中的铝箔的腐蚀;其次,外层涂氟层不仅可以阻止电池灌液中溢出腐蚀问题,同时氟材料自身的稳定性可阻止氧、水对内层铝箔的侵蚀效应,产品综合性能优良,适合消费类电池及动力电池产品的封装应用。
