实验一常用电池材料的循环伏安法测试一．实验目的1．让学生认识电化学工作站的基本功能；2. 通过演示实验让学生更加深刻理解循环伏安法的测试方法；3．通过观察在循环伏安法测试过程中电解池内的变化，更加深刻理解循环伏安法的原理。

二．实验原理循环伏安法（Cyclic Voltammetry）是一种常用的动电位暂态电化学测量方法，是电极反应动力学、反应机理以及可逆性研究的重要手段之一，应用非常广泛。

何。

三．主要实验设备及样品1. 电化学工作站 1台；2. 电解池（包括三个电极） 1套；3. 超级电容器电极材料4. 3mol/L KOH溶液 30ml四．实验步骤1．准备好待测电极，电解液，组装好三电极电解池。

2．连接电化学工作站电源，并启动。

3. 将电化学工作站测试端和电解池中的工作电极，参比电极，辅助电极一一对应进行连接。

4. 打开电化学工作站工作菜单，点击进入测试任务选项，选择Cyclic Voltammetry项。

5. 在Cyclic Voltammetry菜单中输入测试起始电压，结束电压，扫描速度，循环次数等参数。

6. 点击“开始”进行测量。

7.测量结束后，将数据保存到指定位置。

五．注意事项1. 实验前需要检查电解池组装是否规范，有无漏液，或者短路情况；2. 连接三电极时，要一一对应。

3. 数据注意及时保存六. 数据记录及处理数据记录（取第二圈数据）Temperature('C): 25Begin Information: Cell InformationSurface Area: 1Density: 7.8Weight: 28Polarity: 0PolarityI: 0Corrosion Unit Type: 1Reference Type: 2Reference
