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测量了固态电池中LiCoO2阴极和LiPON电解质表面的能带图。LiCoO2和LiPON表面的UPS/LEIPS光谱如图6所示。从LiCoO2表面获得的带隙为2.4 eV,与报道的实验带隙2.1–2.7 eV密切相关。对于LiPON,带隙为5.2eV,略低于其理论带隙∼6.0eV。
