Abstract

Li1+xMn2O4-δ thin films were deposited on plain or coated (Au, Pt, Au/Pt) glassy carbon substrates using pulsed laser deposition. The aim of the coating was to improve the conductivity and the adhesion between film and substrate. The application of different intermediate layers influenced the crystallinity, the surface morphology, and the cycle stability of the spinel films. Films deposited on Au/Pt coated glassy carbon showed the most intense (111) orientation and the best defined surface morphology with tetrahedral and octahedral particle shapes. Compared to films on other metallic layer/glassy carbon combinations, Li1+xMn2O4-δ films on Au/Pt coated substrates displayed the lowest cycle stability..
