Description
技术领域
本发明涉及安全型电池外壳技术领域,具体为一种安全型锂电池外壳。
背景技术
锂电池在人们日常生活及工作中应用非常广泛,锂电池以其比能量高、安全性好、使用寿命长、环境友好等优点被广泛应用于电子、通讯、电动工具、电动车辆、储能、航空航天,等领域、锂离子电池主要依靠锂离子在正极和负极之间来回移动进行工作、锂电池在使用中会散发大量的热量,热量导致锂电池内部温度升高,现在的锂电池散热性能不好,热量在锂电池内难易挥发,时间越长温度越高,最终可能会有爆炸危险,电池外壳主要用于保护电池内部芯片防止外界氧气及水分等与电池内部接触。
但是,传统的锂电池外壳存在一些弊端如;
1、传统锂电池外壳钢壳、铝壳等金属外壳采用全封闭式,由于锂电池在使用中会产生大量的热量,采用传统锂电池外壳的锂电池由于缺乏散热装置工作时产生的热量排不出去,热量导致电池内部温度急剧升高,这样不仅会缩短电池使用寿命而且温度过高电池内部会发生爆炸,严重时会威胁使用者生命。
传统锂电池外壳由壳体和锂电池底板组成,底板为平面结构,在电池内部压力增大的情况下,底板会向外突出使其变形、爆裂、甚至爆炸,影响电池的使用寿命,而且,会危害人身安全,而且传统的锂电池外壳大多为金属外壳,这种外壳不仅重量大,耐腐蚀性和绝缘性也不好,从而使电池易发生鼓胀和电极腐蚀。
发明内容
本发明的目的在于提供一种安全型锂电池外壳,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:一种安全型锂电池外壳,包括金属盖、电芯、内壳体、外壳体,所述外壳体内部固定设置有内壳体,所述内壳体内部固定设置有电芯,所述内壳体顶部固定设置有金属盖,所述金属盖底部位于内壳体内固定设置有塑料板,所述塑料板顶部固定设置有阻隔层,所述阻隔层是中间为铝箔层两侧为塑料膜层的铝塑复合膜层,所述阻隔层与金属盖之间固定设置有空腔,所述电芯底部通过导线固定连接有锂电池底板,所述内壳体外壁上固定设置有一层导热硅胶,所述内壳体与外壳体之间固定设置有翅形散热片,所述翅形散热片通过导热硅胶粘贴在内壳体表面,所述外壳体上均匀固定开设有散热孔。
进一步的,所述散热孔的孔径为2mm。
进一步的,所述锂电池底板底部中心设置为向内凹陷的圆弧槽。
进一步的,所述金属盖顶部中心设置有向外突出的凸起接触端。
进一步的,所述内壳体与电芯之间填充有电解质液体。
与现有技术相比,本发明的有益效果是:
1、本发明通过在电芯外侧设置两层壳体以及在壳体间设置电解质溶液及导热硅胶,可以将运行中的锂电池产生的热量迅速导出,避免是锂电池本身温度过高,后热量通过翅形散热片以及固定设置在外壳体上的散热孔散出大气当中,避免了锂电池过热而发生爆炸,
本发明锂电池底板为中心向内凹陷并由中心向外部圆滑过渡,在电池内部压力增大的情况下逐渐变成平面状态,不会向外突出,避免发生爆炸,除此之外本发明在塑料板顶部设置有阻隔层,阻隔层提高了锂电池外壳的阻隔性,增强了锂电池的耐腐蚀性,显著提高了锂电池的使用寿命降低了锂电池使用过程中的膨胀,容量衰减等异常情况。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
请参阅图1,本发明提供一种技术方案:一种安全型锂电池外壳,包括金属盖1、电芯2、内壳体3、外壳体6,所述外壳体6内部固定设置有内壳体3,所述内壳体3内部固定设置有电芯2,所述内壳体3顶部固定设置有金属盖1,所述金属盖1底部位于内壳体3内固定设置有塑料板8,所述塑料板8顶部固定设置有阻隔层9,所述阻隔层9是中间为铝箔层两侧为塑料膜层的铝塑复合膜层,所述阻隔层9与金属盖1之间固定设置有空腔,所述电芯2底部通过导线固定连接有锂电池底板10,所述内壳体3外壁上固定设置有一层导热硅胶4,所述内壳体3与外壳体6之间固定设置有翅形散热片5,所述翅形散热片5通过导热硅胶4粘贴在内壳体3表面,所述外壳体6上均匀固定开设有散热孔7.
所述散热孔7的孔径为2mm,可以更好地将热量散出去而又不会因为孔径过大而使锂电池内部进入杂质,通过所述锂电池底板10底部中心设置为向内凹陷的圆弧槽,以及所述金属盖1顶部中心设置有向外突出的凸起接触端,使金属盖1上部的突起能够与电池底板10底部的圆弧槽相配合使用,增强本发明组合使用的能力,所述内壳体3与电芯2之间填充有电解质液体。
工作原理:使用锂电池时锂电池产生大量热量,温度上升,温度通过导热硅胶4进入翅形散热片5,翅形散热片5将热量散发减少锂电池内部热量,同时热量再经外壳体6上的散热孔7散出到大气中。
尽管已经示出和描述了本发明的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本发明的范围由所附权利要求及其等同物限定。
