介绍了核磁共振波谱技术在锂离子二次电池正极材料研究中的应用。这篇综述文章中描述的研究清楚地表明，现在可以从这些材料的光谱中获得丰富的信息，即使是在顺磁或金属状态下，无论是在电池的电化学循环之前还是之后。首先，我们回顾了在斯托尼布鲁克和其他地方进行的工作，最初发展的位移机制，导致在顺磁性锰酸锂光谱的大位移的详细了解，然后，应用这些知识来探测局部结构和电子性质的范围内的材料。然后简要讨论了更广泛的阴极材料的NMR。最后简要介绍了该领域常用的实验方法。(C)2003年，Elsevier SAS科学与医学版。All rights reserved.
The application of NMR spectroscopy to study the cathode materials used in lithium-ion rechargeable batteries is described. The research described in this review article clearly demonstrates that it is now possible to obtain a wealth of information from the spectra of these materials, even in the paramagnetic or metallic state, both prior and following electrochemical cycling of a battery. First, we review the work performed at Stony Brook and elsewhere, initially to develop a detailed understanding of the shift mechanisms that result in the large shifts in the spectra of paramagnetic lithium manganates, and then, to apply this knowledge to probe local structure and electronic properties in a range of materials. NMR of a wider range of cathode materials is then briefly discussed. Finally, the experimental methods typically used in this field are briefly described.
