本章主要讨论了核磁共振技术在锂离子电池中的应用。结果表明，锂离子在负极碳材料中的观察较为直观，并实现了充放电过程中的原位核磁共振。介绍了用魔角自旋（MAS）技术检测电极材料中各种核自旋的固态核磁共振。进一步讨论了利用脉冲场梯度技术测量锂离子电池的扩散系数和观察锂离子电池的磁共振成像（MRI）。
In this chapter, the application of nuclear magnetic resonance (NMR) to lithium-ion batteries is discussed. It is shown that observation of lithium in anode carbon materials is straightforward and in situ NMR during charge/discharge has been realized. Examination of solid-state NMR of various nuclear spins in electrode materials using a technique called magic-angle spinning (MAS) is introduced. Further, measurement of the diffusion coefficient and observation of magnetic resonance imaging (MRI) of lithium-ion batteries using the pulsed-field-gradient technique are discussed.
