Change in Li depth profiles of Ti/NbO/LiPON/LMO/Ti and Ti/LMO/LiPON/NbO/Ti (NbO=Nb₂O₅, LiPON=Li_3.3PO_3.8N_0.2, LMO = LiMn₂O₄) batteries prepared on Si substrate on one cycle of charging and discharging has been in-situ measured from both Ti/NbO and Ti/LMO sides by ERD (elastic recoil detection analysis) and RBS (Rutherford backscattering spectroscopy) techniques with 9 MeV O⁺⁴ ion beam, in order to understand Li transport between NbO to LMO. It is found that on over-charging of the Ti/NbO/LiPON/LMO/Ti battery Li charged in NbO diffuses into top Ti film, but on the Ti/LMO/ LiPON/NbO battery Li does not diffuse into bottom Ti film, but returns back to LMO, reacts with top Ti film and segregates at the Ti surface. The difference in Li transport in both batteries is discussed in terms of the difference in Fermi levels at the interfaces of LMO/Ti and NbO/Ti on the Si substrate.

Ti/NbO/LiPON/LMO/Ti 和 Ti/LMO/LiPON/NbO/Ti (NbO=Nb ₂ O ₅ , LiPON=Li _3.3 PO _3.8 N _0.2 , LMO = LiMn ₂ O ₄ ) 电池的锂深度分布变化已通过 ERD（弹性反冲检测分析）和 RBS（卢瑟福背散射光谱）技术使用 9 MeV O ⁺⁴从 Ti/NbO 和 Ti/LMO 两侧原位测量了在一次充电和放电循环中在 Si 衬底上制备的离子束，以了解 NbO 到 LMO 之间的锂传输。发现在 Ti/NbO/LiPON/LMO/Ti 电池过度充电时，在 NbO 中充电的 Li 扩散到顶部 Ti 膜，但在 Ti/LMO/LiPON/NbO 电池上，Li 没有扩散到底部 Ti 膜，但返回到 LMO，与顶部 Ti 膜反应并在 Ti 表面偏析。两种电池中 Li 传输的差异是根据 Si 衬底上 LMO/Ti 和 NbO/Ti 界面处的费米能级差异来讨论的。
