摘要

测试某知名进口和国产的A款和B款18650磷酸铁锂动力电芯在室温(25 ℃)、低温(–20 ℃)和高温(55 ℃)下不同放电倍率的温度性能、产热行为和电化学性能

分析两款电芯放电容量、放电电压平台、交流阻抗、电芯过充循环后直流内阻随着荷电状态的变化规律. 结果表明环境温度和放电电流越高

电芯最高温度和温升斜率急剧增加; 室温10 C放电时

B款最高温度比A款增加13.2%; B款电芯低温工况大电流放电时

电芯仅放出2.65%的电量

几乎失去正常放电电压平台; 电芯的直流内阻随着荷电量的增加呈下降的趋势

过充导致电芯的直流内阻最大增加24.19%.

Abstract

In order to obtain the temperature properties and heat generation behaviors about different levels of power batteries and provide theoretical guidance for practical industry application

the well-known import and domestic（Type A and Type B）18650 lithium iron phosphate power batteries with the similar technical parameters were selected for researching the heat generation behaviors and electrochemical properties with various discharge rates under different working conditions

including room temperature (25 ℃) and ultra-low temperature (–20 ℃) and higher temperature (55 ℃). The discharge capacity

discharge voltage platform

electrochemical impedance spectroscopy were conducted and analyzed. The impact of different states of charge (SOC) on internal resistance after overcharge cycles was summarized. Testing results indicate that the higher the ambient temperature and the discharge current

the higher the maximum temperature and temperature rise gradient. Compared with Type A battery

peak temperature of Type B increased by 13.2% at room temperature with 10 C discharge current. What is worse

Type B battery only emits 2.65% of the nominal capacity with 3 C discharge rate and nearly loses the normal discharge voltage platform under ultra-low condition. The internal resistance decreased with the SOC increase

which increased by 24.19% caused by the overcharge operations.
