Experimental data of three lithium-ion batteries under galvanostatic discharge tests at different C-rates and operating temperatures

Hardware: • Arbin Instruments LBT21024 and Arbin measurement system; • IncuMax IC-500R thermal chamber Arbin Instruments LBT21024; • T-type thermocouple sensor, Omega. Software: • MITS Pro software and Data Watcher. The Arbin system supplies the user-defined current to the battery and measures voltage and surface temperature responses. Once the battery is fully charged (after the CC-CV protocol), a galvanostatic discharge profile is applied until the voltage cutoff limit is reached (2.5V for NCA and NMC, 2V for LFP chemistry). The type-T thermocouples are placed at the center location and measure the battery skin temperature. The ambient temperature is controlled by the user via the thermal chamber.### 硬件配置： • 阿宾仪器（Arbin Instruments）LBT21024 型设备及Arbin测量系统； • IncuMax IC-500R 型热环境箱； • T型热电偶传感器（Omega品牌）。 ### 软件配置： • MITS Pro软件与Data Watcher数据监控软件。 Arbin测量系统可为电池提供自定义输入电流，并同步采集电压与表面温度响应信号。当电池通过恒流恒压（CC-CV）充电协议完成满充后，施加恒流放电程序直至达到电压截止阈值：NCA与NMC化学体系电池的截止电压为2.5V，LFP化学体系电池为2V。T型热电偶布置于电池中心位置，用于采集电池外壳表面温度。环境温度由用户通过热环境箱进行精准调控。
