锂离子电池具有质量轻,电压高,寿命长等优点,在消费电子和动力产品领域均有广泛地应用.不同温湿度条件对锂离子电池性能的影响是一个重要研究领域,尤其是在电池的存储和运输阶段.本文主要研究钴酸锂电池在不同SOC,不同温度不同湿度下的电压、内阻、厚度和容量变化,并对存储环境和条件提出了相应的建议.
Study of the Performance of Lithium Ion Battery in Different Storage Conditions
Owing to light weight,high voltage,and long lifespan,lithium ion battery is widely used in both consumer electronics and power products fields.The impact of varying temperature and humidity conditions on lithium-ion battery performance is an important research domain,particularly during the battery's storage and transportation phases.This paper primarily investigates the changes in open circuit voltage,internal resistance,thickness and capacity of cobalt oxide(LiCoO2)based lithium-ion batteries under different states of charge(SOC),across a range of temperatures and humidity levels.Moreover,it provides recommendations for appropriate storage environments and conditions accordingly.
