中文摘要:
      目的研究低温环境条件下温度对某型军用方形锂离子电池放电性能的影响。方法参照标准GB/T18287，在常温下将锂离子电池进行充电，再在高低温潮湿试验箱中按设定低温条件利用电池测试仪进行放电性能测试，并将不同温度测试结果利用加速模型结合Arrenhenius方程进行拟合。结果该型军用锂离子电池放电容量随温度下降而降低，在-30℃温度条件下电池的放电容量相当于室温放电容量的20.9%，并在低于-40℃温度条件、2.5V截止电压下无法放电。结论通过低温条件放电性能测试，并对温度条件和放电容量进行建模，得出绝对温度倒数与电池容量保留率对数在25~-35℃温度区间内分两段成线性相关。

      ObjectiveTo study the discharge performance of a certain type of military square lithium-ion battery under low temperature conditions.MethodsLithium-ion battery was charged at room temperature referring to standard GB/T18287，and the discharging performance was tested in the low-temperature test chamber at a set temperature and the results at different temperatures were fitted to the accelerated model combined with Arrenhenius equations. Results The discharge capacity of battery decreased with the decrease of temperature，and the discharge capacity of the battery at -30℃was equivalent to20.9% of that at room temperature and could not be discharged below -40℃at2.5V cut-off voltage.ConclusionThrough the discharge performance test under low temperature conditions，and modeling for the temperature and discharge capacity，the results showed two linear fashions between the reciprocal of absolute temperature and the logarithm of the capacity from25℃to -35℃.
