摘　　要：锂离子电池作为一种清洁高效的储能介质,在储能领域大规模应用的同时,也伴随着巨大的安全隐患。无论是在电池制造阶段,还是服役阶段,提前发现电池内部缺陷或者失效行为都能有效降低安全事故发生的概率。常规的拆解检测方法虽然能够直观地观察到电池内部失效后的特征,但是这种检测方法带来的破坏性是不可逆的。无损检测技术能够在真实的环境和使用工况下对电池实施原位检测分析,具有非破坏性、实时检测等优点,能够精准反馈电池失效、寿命衰减等动态变化过程,有助于进一步优化材料设计、精进电池制造过程、提升电池安全水平。综合评述了国内外研究人员在基于X射线成像、计算机断层成像、中子散射、超声波探测、电化学阻抗谱等方向开展的锂电池无损检测相关工作,并对各类方法的工业化应用前景进行了展望。As a clean and efficient energy storage medium,the lithium-ion batteries have been applied on a large scale in the field of energy storage,but also accompanied with huge security risks.Whether in the battery manufacturing stage or service stage,the early detection for the internal defects or failure behavior of the batteries can effectively reduce the probability of safety accidents.Although the conventional disassembly detection methods can intuitively observe the characteristics of the battery after internal failure,the damage brought by the detection method is irreversible.The nondestructive testing technology can carry out in-situ detection and analysis of batteries under the real environment and working conditions,has the advantages of nondestructive and real-time detection,and can accurately feedback the dynamic changes such as battery failure and life decay,which helps to further optimize material design,improve battery manufacturing process,and improve battery safety level.The works of nondestructive testing of lithium-ion batteries based on X-ray imaging,computed tomography imaging,neutron scattering,ultrasonic detection,electrochemical impedance spectroscopy and other directions were reviewed,and the industrial application prospects of various methods were prospected.
