Abstract：In the production and application of lithium-ion batteries,electrical performance testing is an indispensable and crucial step.Electrical performance testing of lithium-ion batteries is a core aspect that ensures their safety and optimizes research and development.This study addresses the testing requirements for key electrical performance indicators(capacity,capacity retention rate,cycle stability)of lithium-ion batteries by employing multiple charge-discharge cycling test schemes.By collecting data under different charge-discharge schemes,corresponding voltage-capacity curves and capacity fade curves are plotted.The tests show that testing conditions such as temperature,cut-off voltage,and rate all affect the capacity retention rate of lithium-ion batteries,leading to a noticeable decrease in battery life.The decay curves generated through data visualization clearly identify the process of battery capacity fade.This study not only provides quantitative criteria for screening lithium-ion batteries but also offers data support for their research and development.
