摘　　要：锂离子电池因其高能量密度、环保性和长循环寿命等优点,近年来已广泛用于各种储能应用。然而,储能电池运行安全问题频繁发生,稳定性和可靠性等方面仍需改进。目前,检测锂离子电池温度和应变的方法主要包括热电偶温度传感器、电阻温度传感器和电阻应变计等。然而,这些方法存在一些限制,例如不能全面测量电池整体温度,以及传感器尺寸较大,难以嵌入电池内部。在此基础上介绍了几种基于FBG的储能锂离子电池温度与应变监测技术,同时比较了它们之间的优点和缺点,最后总结并展望了FBG在锂离子电池温度与应变监测中的发展前景。Lithium-ion batteries have been widely used in various energy storage applications in recent years due to their advantages such as high energy density,environmental friendliness,and long cycle life.However,safety incidents during the operation of energy storage batteries are frequent,and issues related to stability and reliability need urgent solutions.Currently,methods for detecting the temperature and strain of lithium-ion batteries mainly include thermocouples,resistance temperature sensors,and resistance strain gauges.However,these methods have limitations,such as the inability to comprehensively measure the overall temperature of the battery and the challenge of accommodating large-sized sensors inside the battery.This paper,based on this background,introduces several temperature and strain monitoring techniques for energy storage lithium-ion batteries based on Fiber Bragg Grating(FBG)technology,compares their advantages and disadvantages,and finally summarizes and prospects the development prospects of FBG in temperature and strain monitoring of lithium-ion batteries.
