Relaxation data for commercial NMC and LFP cells
收藏资源简介：
Benchmark Relaxation Dataset ++++++++++++++++++++++++++++++ This dataset contains the electrochemical and relaxation data referenced in the publication entitled 'Benchmark dataset for the study of the relaxation patterns of commercial NMC811 and LFP cells' published in Cell Reports Physical Science. The dataset includes data gathered during the execution of protocol 1 and protocol 2, established in the paper. The full electrochemical data consists of MACCOR txt files with the full cell history of one cell per folder. Details for each cell is included in a readme file included in each folder. P1 stands for protocol 1 and P2 for protocol 2. UP and DOWN refers to the temperature direction for protocol 2. UP was used when the temperature increased from 25 to 55oC in 5oC increments. DOWN was used when the temperature was decreased from 30 to -15oC in 5oC increments. The relaxation only data is contained in a zip file with ".mat" extensions, which follows the binary format used by MATLAB. The data within each file is organized based on the relaxation following charge or discharge cycles. Within each relaxation data double, five columns are present: 1. Voltage (V) 2. Time (s) 3. C-rate of the previous step (hr) 4. Depth-of-discharge (%) 5. Temperature (degC) More information is provided in the readme file. Examples of utilization are provided in the m file.
基准弛豫数据集 ++++++++++++++++++++++++++++++++++ 本数据集包含发表于《细胞报告·物理科学》（Cell Reports Physical Science）的论文《用于商用NMC811与磷酸铁锂（Lithium Iron Phosphate, LFP）电芯弛豫模式研究的基准数据集》中引用的电化学与弛豫数据。 本数据集涵盖论文中确立的测试方案1与测试方案2执行过程中采集的全部数据。 完整电化学数据为MACCOR格式的txt文件，每个文件夹对应单颗电芯的完整充放电历史。 每个文件夹内的README文件均包含对应电芯的详细信息。 文中P1代表测试方案1，P2代表测试方案2。 UP与DOWN分别指代测试方案2的温度调控方向：当温度以5℃为步长从25℃升至55℃时采用UP模式；当温度以5℃为步长从30℃降至-15℃时采用DOWN模式。 仅包含弛豫数据的文件打包为扩展名为.mat的压缩包，该格式遵循MATLAB的二进制数据规范。 每个文件内的数据均按照充放电循环后的弛豫过程进行组织。 每组双精度弛豫数据均包含五列信息： 1. 电压（V） 2. 时间（s） 3. 前一步骤的充放电倍率（hr） 4. 放电深度（%） 5. 温度（℃） 更多细节可查阅各文件夹内的README文件。 相关使用示例可参考配套的m文件。
