Abstract

本实用新型是一种锌氯蓄电池，主要特点是对现 有蓄电池加以改进，在石墨电极上加工有多孔，并在 孔内放置有一定量的活性物质，与现有同类蓄电池比 较，充电电压达到2.1伏，工作电压高，达到1.6～ 1.8V，终了电压低，降到0.75V时仍可放出电能，输出 容量大，以干电池R20的尺寸可以达到2Ah等优 点。

Description

本实用新型属于基本电气元件技术领域，是一种锌氯蓄电池。
现有的锌氯蓄电池，以锌为负极，以石墨为正极，以ZnCl2溶液为电解液。在氯离子还原为氯气后，由于石墨的吸附能力较弱，还原为氯气的量少，因而存在着工作电压低，输出容量小的缺点。
本实用新型的目的在于设计一种工作电压较高，输出容量较大的锌氯蓄电池。
本实用新型所采用的技术措施是对现有的锌氯蓄电池加以改进，在石墨电极上加工成多孔，并在多孔内加入活性物质。
本实用新型锌氯蓄电池：1、由于在石墨中加入碘，充电时电解液中产生的氯气与正极内的碘生成卤素互化物ICl，和ICl3并吸附在活性碳和石墨电极孔内增加了氯气的蓄存量，蓄存时间长。2、由于ICl和ICl3的化学性质类似于卤素单质，是氧化剂，具有很强的化学活性，在放电时，在ZnCl2溶液中生成Cl－，成为正极的活性物质，可使充电电压达到2.1伏，工作电压达到1.6伏以上。输出容量，以干电池R20的尺寸达到2Ah，充放电300次左右，适用－20℃－50℃温度范围。
结合附图及实例介绍本实用新型锌氯蓄电池的结构特征。
附图表示本实用新型锌氯蓄电池的结构示意图。
参见附图，本实用新型锌氯蓄电池包括：铜帽1，碳棒2，塑料盖3，排气空4，密封垫5，下塑料盖6，泡沫塑料7，锌外壳8，隔膜9，垫片10，电解液11，多孔石墨电极12，装入石墨电极孔内的活性物质碘13。
使用时，在充电期，在负极，ZnCl2溶液中Zn＋＋在负极获得电子还原为Zn原子，沉积在锌极上。在正极，溶液中的Cl－吸附在石墨电极微孔内变化氯气，氯与石墨中的有碘形成卤素互化物ICl和ICl3，采用碘作为氯的载体，氯气被蓄存起来，增加了氯的蓄存量，放电期，ICl和ICl3在ZnCl2溶液中生成Cl－离子，负极Zn失去电子成为Zn离子，由于增加了氯的蓄存量，从而增加了输出电压和容量。
