技术领域
本发明涉及包装材料技术领域,具体涉及一种锂电池组包装材料。
背景技术
“锂电池”,是一类由锂金属或锂合金为负极材料、使用非水电解质溶液的电池。锂电池体积小,容量大,电压稳定,可以循环使用,安全性强,这是最快的,减少污染,有利于可持续发展。目前市场上存在的锂电池使用的包装材料多为pvc热缩套管,无透气性而且材料较为脆弱,不利于锂电池组的运输和搬运。
发明内容
本发明提供了一种锂电池组包装材料,以解决现有技术存在的透气性和材料脆弱不利于锂电池组运输的问题。
本发明解决其技术问题所采用的技术方案是:
一种锂电池组包装材料,具有网状结构,由芳纶纤维粉末与pvc热缩材料合成,芳纶纤维粉末与pvc热缩材料的使用质量比例为1:1~1:3之间。
上述芳纶纤维粉末与pvc热缩材料的使用质量比例为1:2。
上述锂电池组包装材料的生产工艺,以芳纶纤维粉末与pvc热缩材料为原料,将芳纶纤维粉末与pvc热缩材料按照约比例均匀混合后,在120℃温度下和14兆帕压力下熔合,然后经模压机压制形成网状板料。
本发明提供了一种锂电池组包装材料,网状结构使得锂电池的散热性能更好,弥补了电池发热的缺陷,采用芳纶与pvc形成复合材料,增加了包装膜的强度,可起到直接保护作用,避免电池***引起的损伤,弥补了锂电池易爆的缺点。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明铝电池组包装材料的结构示意图。
具体实施方式
如图所示,一种锂电池组包装材料,具有网状结构,由芳纶纤维粉末与pvc热缩材料合成,芳纶纤维粉末与pvc热缩材料的使用质量比例为1:2,锂电池组包装材料的生产工艺,以芳纶纤维粉末与pvc热缩材料为原料,将芳纶纤维粉末与pvc热缩材料按照约比例均匀混合后,在120℃温度下和14兆帕压力下熔合,然后经模压机压制形成网状板料。
