200Ah大容量液态金属电池一致性测试

本数据集数据主要包括200Ah Li-Bi电池以设定程序（搁置-测内阻-恒流放电-搁置-测内阻-恒流充电-循环）运行采集得到电流、电压、充放电时间、容量、能量、内阻等，计算得到容量差异、内阻差异、库伦效率、电压效率。用于支撑大容量液态金属电池的一致性，具体是指电池容量差异小于5 Ah、内阻差异不超过2 mΩ、库伦效率不低于98%、电压效率大于92%。

This dataset mainly collects data from 200 Ah Li-Bi (lithium-bismuth) batteries operating in accordance with a predefined cyclic protocol: rest → internal resistance measurement → constant-current discharge → rest → internal resistance measurement → constant-current charge, with the cycle repeated. The collected parameters include current, voltage, charge-discharge duration, capacity, energy, internal resistance, and other relevant metrics. Additionally, derived indicators such as capacity deviation, internal resistance deviation, Coulombic efficiency, and voltage efficiency are calculated. This dataset is intended to support the consistency assessment of high-capacity liquid metal batteries, where the consistency specifically refers to the following criteria: the battery capacity deviation is less than 5 Ah, the internal resistance deviation does not exceed 2 mΩ, the Coulombic efficiency is no less than 98%, and the voltage efficiency is greater than 92%.
