Characterization of cathode-electrolyte interface in all-solid-state batteries using TOF-SIMS, XPS, and UPS/LEIPS. Journal of Vacuum Science & Technology B 39, 044001 (2021); https://doi.org/10.1116/6.0001044

本文利用UPS以及LIPES測量了固態(tài)電池中LiCoO2陰極和LiPON電解質(zhì)表面的能帶圖。LiCoO2和LiPON表面的UPS/LEIPS光譜如圖6所示。從LiCoO2表面獲得的帶隙為2.4 eV，與報道的實驗帶隙2.1–2.7 eV密切相關(guān)。對于LiPON，帶隙為5.2eV，略低于其理論帶隙～6.0eV。
