Experimental dataset for the performance of VRFB cells with flow fields and different electrode compression ratios

The data presents charge-discharge life cycle behaviour of the vanadium redox flow battery along with pressure drop measurements at various flow rates and current densities for serpentine flow field and design variants of interdigitated flow fields over the three cell areas 400 cm2, 900 cm2 and 1500 cm2 assembled with different electrode compression ratios (20%, 35%, 50% and 70%). Contents include 12 excel sheets. The raw data recorded in BT-Lab software (Biologic) and Visual LCN software (Bitrode) is exported to excel format. Each operating condition consists three life-cycles and the average of them is presented in the excel sheet from which the other parameters like capacity, energy density and efficiency are calculated. Few excel sheets have original raw data exported from the data recording software and many of the sheets have averaged life cycles and processed data for the electrochemical parameters.

本数据集涵盖采用20%、35%、50%及70%四种电极压缩比（electrode compression ratio）装配的三种不同面积（400 cm²、900 cm²、1500 cm²）的钒氧化还原液流电池（vanadium redox flow battery）的充放电循环寿命（charge-discharge life cycle）特性，同时包含蛇形流场（serpentine flow field）与叉指式流场（interdigitated flow field）的多款设计变体，在不同流速（flow rates）和电流密度（current densities）下的压降（pressure drop）测量数据。
本数据集共包含12个Excel工作表。原始实验数据由BT-Lab软件（Biologic）与Visual LCN软件（Bitrode）记录，并导出为Excel格式。每个运行工况包含3次循环寿命测试，工作表中给出测试结果的平均值，并基于该平均值计算得到容量（capacity）、能量密度（energy density）与效率（efficiency）等其他参数。部分工作表存储了从数据记录软件导出的原始实验数据，其余多数工作表则包含经平均处理后的循环寿命数据，以及电化学参数（electrochemical parameters）的处理结果。
