Description
技术领域
本发明涉及电池制作工艺,具体是涉及一种电池组的封装方法及电池组。
背景技术
如图1所示,现有技术中将多个单体电芯1封装为电池组时,依靠封装盒2内的纵横支架3稳定各个电池,以保持各个单体电芯1在封装盒2内的位置稳定不动。但实际使用中发现,由于单体电芯间存在间隙4,在电池组搬运或使用中受到震动后电芯仍然会晃动,而一些电池的载流片脱焊与此原因有关。
发明内容
本发明要解决的技术问题是提出一种电池组的封装方法,使得电池组的整体结构更稳定,避免单体电芯的晃动和相互之间的碰撞问题。
本发明的技术方案为:
这种电池组的封装方法包括将单体电池置于封装盒内的步骤、填料步骤、封闭封装盒的步骤,其中,填料步骤中向封装盒内的单体电池之间的间隙处填入填料。
优选的方案中,填料步骤中,所述填料为混炼胶。
所述混炼胶由聚异丁烯和石蜡混炼而成。
所述填料步骤包括以下步骤:1)将聚异丁烯和石蜡按重量比35~45∶55~65的配比称重,放入混炼设备中于70℃~100℃温度条件下混炼1~3小时,待聚异丁烯和石蜡完全熔化后搅拌均匀,形成混炼胶;2)将混炼胶注入封装盒内的单体电池之间的间隙处,冷却混炼胶使其凝固。
优选的方案中,步骤1)中将聚异丁烯和石蜡按重量比40∶60的配比称重。
本发明还提出一种采用以上方法制作的电池组,包括封装盒及置于封装盒内的多个单体电池,在封装盒内的单体电池之间的间隙处还填有填料,从而将各个单体电池固定在封装盒内。
优选地,所述填料为由聚异丁烯和石蜡混炼而成的混炼胶。
本发明与现有技术对比的有益效果是:在电池组封装盒的单体电池的间隙处都填入填料,从而固定了每个电池,避免了电池在封装盒内的晃动和相互之间的碰撞,尤其在电池组搬动和运输时电池的保护效果明显。填料采用聚异丁烯和石蜡改性混合而成的混炼胶,不但混炼胶的制造工艺简单、成本低廉,而且混炼胶具有良好的抗震、吸震功能;同时由于可以采用注塑工艺将混炼胶注入封装盒的间隙中,也使得填料步骤简单可靠、容易实现。
附图说明
图1是电池组封装的结构示意图。
具体实施方式
在现有的电池组封装过程中,如图1所示,将单体电池1放入封装盒2内后,一般都通过纵向布置或/和横向布置的固定支架3将单体电池1隔开,然后再合上盒盖,封闭封装盒。
由于放置后圆形(或其他形状)的单体电池1之间存在的间隙4,单体电池1间就难免会碰撞、晃动。在本实施方式中,在间隙4处填入填料,以隔开各个电池并使得电池组中的电池形成为一体,相互之间不会发生碰撞。
填料采用由聚异丁烯和改性石蜡改性混合而成的混炼胶,聚异丁烯具有粘合作用,可以粘合在电池表面,这样混合胶不容易与电池分离形成新的空隙而减低减震吸震效果。石蜡成本低廉,容易剥离,使用中也不会影响电池的性能。
在间隙4中填料的步骤具体过程如下:
1)将聚异丁烯和石蜡按重量比35~45∶55~65的配比称重,放入混炼设备中于70℃~100℃温度条件下混炼1小时~3小时。待聚异丁烯和石蜡完全熔化后进行搅拌,搅拌时间1.5小时~2.0小时,使得混合聚异丁烯和石蜡材料相互混合均匀,形成混炼胶。
2)使用注塑设备,将混炼胶注入封装盒内的单体电池之间的间隙4处,静置冷却,使得混炼胶凝固。
上述步骤1)中优选将聚异丁烯和石蜡按重量比40∶60的配比称重,可以发挥较好的粘合与填充作用。石蜡采用改性石蜡可降低成本,提高绝缘性、密封性。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明,不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本发明的保护范围。
