优秀论文｜电池绝热量热仪研究低温循环老化对高镍8系电池热特性和产气特性的影响

重庆理工大学齐创副教授、林春景副教授、刘真言同学等的课题组在 Applied Thermal Engineering 期刊发表题为 Study on the effect of low-temperature cycling on the thermal and gas production behaviors of Ni_0.8Co_0.1Al0.1/graphite lithium-ion batteries。

本项目采用了小型电池绝热量热仪BAC-90A 作为主要测试仪器，通过对NCA811锂离子电池进行低温循环老化，并分析SOH与比热容、产热特性和产气特性的关系。

部分研究成果展示

本研究中 BAC-90A 的应用：

1. 单体比热容测试

比热容是进行锂电池热管理系统瞬态仿真的关键热物性参数，用于定量分析电池产热特性与研究电芯间热传递规律等。小型电池绝热量热仪是测定电芯比热容的有效手段。

（非本论文内容，仅作示例）

2. 充放电产热测试

锂离子电池老化程度的变化会导致相应产热功率的变化，进而影响电池的寿命和安全性。小型电池绝热量热仪BAC-90A 的充放电模块可准确反应电池在充放电过程中放热量及放热速率。

3. 热失控测试及产气分析

HWS模式是最常规的分析模式，可准确获得热滥用条件下的电池热失控特征参数。此外，小型电池绝热量热仪也可利用定制密封测试罐同步完成电池热失控产气压力测试及气体收集，大幅提升试验效率与测试结果可靠性。
