Description

一种钮扣型电池
[技术领域]
本实用新型涉及一种直流电源，特别是一种可以作为便携式电子产品电源使用的钮扣型电池。
[背景技术]
钮扣型电池以其较小的体积、较高的电容量而被广泛应用于各种便携式电子产品中。现有技术中钮扣型电池(例如锂电池)的结构，一般是将电池正、负极片及隔膜卷成圆筒(圆柱)状，然后再压扁(压平)形成矩形(正方形)的电极片，再放入电池壳体。由于钮扣型电池的壳体截面为圆形，正方形的电极片放入其中必然导致正方形四个边对开的壳体空间无法利用，从而使电池的电容量受到限制。此外，现有技术产品的结构决定了其正、负极导引须采用点焊方式与电池(正极)壳体及(负极)盖连接，增加了工序，降低了效率，提高了成本。
[发明内容]
本实用新型的目的在于克服现有技术的不足之处，提供一种能充分利用电池壳体内空间、电池电容量较大且在制造时能减少工序、降低成本的钮扣型电池。
本实用新型的目的是这样实现的：钮扣型电池包括壳体(1)、面盖(2)、设置于壳体与面盖连接部的密封圈(3)及设置于壳体内的组合电芯，其特征在于组合电芯由电极片组构成，电极片组由一正极片(4)和一负极片(5)组成；组合电芯的横截面形状、大小与壳体内腔吻合。组合电芯包括一个或一个以上电极片组，电极片组之间有绝缘片(6)分隔。
本实用新型结构合理，能有效增加电池容量，且可以使电池组装工序简化，从而提高了效率、降低了成本。
[附图说明]
图1是本实用新型的主要结构图。
图2是本实用新型实施例1的组合电芯结构示意图。
图3是本实用新型实施例2的组合电芯结构示意图。
图号说明：
1--壳体    2--面盖    3--密封圈    4--正极片
5--负极片  6--绝缘片  7--隔膜      8--周边封口
[具体实施方式]
钮扣型电池包括壳体(1)、面盖(2)、设置于壳体与面盖连接部的密封圈(3)及设置于壳体内的组合电芯，其特征在于组合电芯由一个或一个以上电极片组层叠而成，每个电极片组由一正极片(4)和一负极片(5)组成，电极片组之间有绝缘片(6)分隔；电极片组之间串联连接。组合电芯的横截面形状、大小与壳体内腔吻合。
电池的正极片由金属箔(例如铝箔)和正极料(例如锂化合物)组成，负极片由金属箔(例如铜箔)和负极料(例如碳粉)组成，正极片(4)被隔膜(7)包掩后与负极片叠合，形成一个电极片组。隔膜(7)包掩正极片(4)，周边可以不封口。但为了防止正极片(4)滑出隔膜(7)包掩范围以外与其他电极片误接触，周边也可以部分封口或全封口。
当然，也可以采取如下实施方式：电池的正极片由金属箔(例如铝箔)和正极料(例如锂化合物)组成，负极片由金属箔(例如铜箔)和负极料(例如碳粉)组成，负极片(5)被隔膜(7)包掩后与正极片叠合，形成一个电极片组。隔膜(7)包掩负极片(5)，周边可以不封口。但为了防止负极片(5)滑出隔膜(7)包掩范围以外与其他电极片误接触，周边部分也可以部分封口或全封口。
正、负极片及层叠而成的组合电芯的形状尽量与壳体形状一致(须留出电极导引所需位置)，并尽量充填壳体内空间，将圆形的面积尽量利用，以加大电容量。在组装方面，由于正、负极片导引采用接触式，无须焊接，从而简化了工序，提高了效率，降低了成本。
