摘要
提出了一种在锂离子电池制作过程中粘贴镀金光纤布拉格光栅(FBG)传感器的锂离子电池原位检测方法,该方法可用于采集锂离子电池的初始物理量。研究了将镀金FBG传感器埋入锂离子电池的位置及方法,分析了埋入镀金FBG传感器后电池的性能。对锂离子电池进行了充放电实验,并拆封了实验所用的电池样本。实验结果表明,镀金FBG传感器可用于一般环境下的温度采集;锂离子电池中FBG传感器的镀金层遭到腐蚀,导致FBG传感器的波长产生漂移,镀金层避免了裸FBG传感器的结构受到破坏,因此对FBG传感器重新标定后,可采集电池内部的温度。该研究为应用于锂离子电池原位检测的FBG传感器的选择提供了参考。
Abstract
A method of lithium ion battery in-situ detection is proposed. In the proposed method, gold-plated fiber Bragg grating(FBG)sensors are embedded in the making process of lithium ion batteries to acquire the initial physical quantities of lithium ion batteries. The position and the method for the FBG sensor embedded in lithium ion battery are studied, and the performance of battery embedded with gold-plated FBG sensor is analyzed. The charge-discharge experiments for lithium ion batteries are carried out, and the battery samples used in experiments are unpacked. The experimental results show that gold-plated FBG sensors can be used in the temperature collection in general environment. The gold-plated layer structure in the lithium ion battery is corroded, which results in wavelength drift. The bare FBG′s structure is not destroyed due to the presence of the gold-plated layer, so the internal temperature of battery can be collected after re-calibrating FBG sensor. This research provides a reference for the FBG sensor used in in-situ detection for lithium ion batteries.
