Alternating current excitation and voltage measurements - Samsung-30T INR 21700 Battery

The data collection is performed using an Arbin BT-2000 battery cycler. The s.d. of the voltage and current measurement error of the device is approximately 0.00033 V and 0.00025 A, respectively. The sampling time of the data is ∆ = 1 seconds; this resulted in close to 7,200 voltage and current measurements. The VI data can be visualized using the demoVI.m file.本数据集采用Arbin BT-2000型电池循环测试仪完成数据采集。该设备的电压与电流测量误差的标准差（standard deviation）分别约为0.00033 V和0.00025 A。数据采样间隔Δ=1秒，由此可获得近7200组电压与电流测量数据。可通过demoVI.m文件对VI（Voltage-Current）数据进行可视化。
