摘　　要：表征技术的进步对于锂离子电池科学与技术的发展至关重要。一般希望获得锂离子电池材料及电池的广泛信息,包括化学组成、材料形貌、晶体结构、微观组织、表面结构、输运特性、力学特性、热学特性等。本文总结了锂电材料常用的表征技术及其研究现状与发展趋势,包括最近发展的具有高时间和空间分辨的表征手段,如原子力-拉曼光谱联用、原位扫描电镜、原位透射电镜、球差校正扫描透射电镜、扫描透射X射线成像、中子衍射以及二次离子质谱等。Scientific and technological progresses in lithium ion batteries are highly depending on advanced characterization techniques. Various physical and chemical properties are expected to obtain, including chemical composition, morphology, crystal structure, microstructure, surface structure, transport properties, mechanical properties, thermal properties. Here main characterization techniques for investigating lithium ion batteries have been introduced, including several new time and spatial resolved techniques, such as AFM-Raman; in-situ SEM and TEM; spherical aberration-corrected STEM; STXM; neutron diffraction and SIMS.
