Fabrication and Study of All-Solid-State Li-Ion Batteries Based on Self-Organized Titania Nanotubes
In this work, the Li+ insertion into anatase TiO2nts using PEO-based polymer as electrolyte has been studied by cyclic voltammetry (CV) and chronoamperometry (CA). The electrochemical characterizations reveal that that the Li+ storage is dominated by the bulk diffusion (into the lattice) with the contribution of the pseudo-capacitive effect at the surface. Beside the mechanistic investigations, we report the fabrication of the first all-solid-state Li-ion batteries based on titania nanotubes as negative electrode, PMMA-(PEO)5 as polymer electrolyte and LiNi0.5Mn1.5O4 as positive electrode (Fig. 1). The electrochemical performance of this new thin film microbattery will be presented and discussed (Fig. 2).
