中文摘要：
研究商业用18650型锂离子电池（额定容量1150mA．h）的循环寿命衰减规律，利用外推法预测电池的剩余寿命。结果表明，锂离子电池容量保持率与循环寿命服从二次高斯函数关系，匹配检测和一系列的交流阻抗测试验证了所选择的模型的正确性以及精度（〉99％）。建立循环寿命模型有利于缩短电池寿命测试周期，降低预测成本。
英文摘要：
The lifespan models of commercial 18650-type lithium ion batteries （nominal capacity of 1150 mA-h） were presented. The lifespan was extrapolated based on this model. The results indicate that the relationship of capacity retention and cycle number can be expressed by Gaussian function. The selecting function and optimal precision were verified through actual match detection and a range of alternating current impedance testing. The cycle life model with high precision （〉99%） is beneficial to shortening the orediction time and cutting the prediction cost.
