0.45Mn 1.485Cr 0.05O 4 thin films using all-solid-state thin-film batteries]]>

摘要

AbstractTotal electronic conductivity (σetotal) of LiNi0.45Mn1.485Cr0.05O4thin film (LNM–Cr: 40nm in thickness) between 3.5 and 4.9V (vs. Li metal anode) was measured using all-solid-state thin-film battery (Li/LiPON/LPO/LNM–Cr) fabricated on interdigitated array (IDA) electrode. The LNM–Cr with disordered spinel phase was prepared by pulsed laser deposition on the IDA electrode. The σetotaldepended on the voltage and reversibly changed regardless of lithium extraction/insertion process. Variation trends of the σetotalwere in good agreement with the previous reports using the chemically delithiated powder materials. Grain boundary resistance contributes to the σetotaldepending on the voltage probably because of the formation of double Schottky barrier at the grain boundaries.Graphical abstractDisplay Omitted
