Description

一种铅酸电池
技术领域
本实用新型涉及一种铅酸电池。
背景技术
铅酸电池作为一种化学能电池，可将化学能转化为电能，该电池由多个单体电池板组成电池组，相邻的电池板间设有绝缘隔膜，将上述电池组放入到电池盒，充入电解液即可。当电路接通时，通过电解液在两个极性相反的电池板间传输电子。其缺陷在于，单体电池板为平面实体结构，与电解液的接触面积小，导电能力差。由于，电极传输电流的能力正比例于电极与电解液的接触面积，因此现有的平面结构的电池板的导电能力是有限的。
实用新型内容
本实用新型的目的在于提供一种铅酸电池，可增加电池板与电解液接触面积的电池结构，增强导电能力。
一种铅酸电池，由若干个电池单元、绝缘隔膜、电池盒组成，每个电池单元包括一个正极电池板和一个负极电池板，正极电池板和负极电池板之间为绝缘隔膜；所述的电池板包括多孔网状物和实体支架，其中的多孔网状物是一个刚性、可导电、由若干个丝状物连续交叉组成网状物，形成多孔结构，该网状物的表面附着有电池材料，并保持开孔和空间；所述的实体支架粘接于网状物的边缘；电池盒内设置有超声波振动器。
上述的实体支架设在网状物的一边或四周。
本实用新型解决了铅酸电池面临的电子传导的阻滞问题，由于电子的传输受限于电池板暴露于电解液的面积，当接触面的电解液耗尽时，电子的迁移速度就会减慢。其中的电池板的刚性多孔网状物组成的金属织物形成有若干个开口通道，同时这些丝状物相连接的连续节点支持该结构能在各个方向上经受压缩、延展、弯曲、震动、加速等机械冲击。该电池板能够增大与电解液的接触面积，使电极间充分接触，从而减少所需电解液的容量和电池的体积，同时保持足够的机械强度；同时，电池内部增加了超声波振动器，可增加电解液的流动，减少电解液的不均匀性，从而减少电池内阻。
附图说明
图1为本实用新型的结构示意图；
图2为本实用新型的电池板的结构示意图；
图3为本实用新型的电池板的侧视图；
图4为本实用新型的电池板的另一实施例的结构示意图。
具体实施方式
如图1所示，本实用新型提供一种铅酸电池，由4个电池组、绝缘隔膜、电池盒组成，电池盒包括上盖1和下盖6，上盖1上设有进液口9，由进液口9加入电解液到箱体；如果需要也可在电池单元加入电解液排放口。下盖6的侧面设有接电端子4。
图示的电池组由4个电池单元组成，即由4个正极电池板10和4个负极电池板7组成的电极，并在相邻的正极电池板10与负极电池板7之间插入绝缘隔膜8，这些电池板10、7和绝缘隔膜8相邻接形成由4个单元组成的电池组。各个单元间电池为并联的，提供相同的电压各累积的电流。当然也可串联提供累积的电压或通过合适的串联组态获得相应的电流和电压。超声波振动器5放置于最外端的负极电池板7与电池盒体之间，由它产生全部电池板7、10和绝缘隔膜8的超声振动，可保持电池板7、10表面不会产生对电子粘滞的阻力，其频率可设置在20KHZ-120KHZ。电池盒内的上端还设有液位显示仪2及能量水平显示仪3。液位显示仪2显示从液位传感器检测出的电解液液位。
上述的正、负电池板10、7，包括多孔网状物11和实体支架12。如图2、3所示，其中的多孔网状物11是一个刚性、可导的网状物，由若干个几何多边形连续交叉组成网状，形成多孔结构，其表面附着电池材料，并保持开孔和空间，这样最即形成了一个多孔渗透的结构，使得整个电池板暴露，与电池中的电解液充分接触。孔的大小以及织物的大小长度由工艺流程决定。所述的实体支架12粘接于网状物11的上部边缘，其作用是加强整个电池板的机械强度并起到集合电流的作用，该上部边缘连接有一个电极端子13。该电池板也可采用如图4所示的结构，包括多孔网状物11和实体支架12，实体支架12设在网状物11的四周边缘，其中上边缘设有一个电极端子13。
