An interface consisting of LiMn2O4 thin-film (1 mu m thick) electrode and Li1+xAlxTi2-x(PO4)(3)-based NASICON-type solid electrolyte (LTP) was prepared by a sol-gel coating method. The submicron-sized pores were involved in the thin film, and the porosity of the film was relatively high. The prepared solid-solid electrochemical interface was evaluated by cyclic voltammetry and galvanostatic charge-discharge test. Two reversible redox peaks were observed at 4.0 and 4.1 V versus Li/Li+ in the cyclic voltammogram due to the redox of Mn3+/(4+). The LiMn2O4 thin-film electrode on LTP exhibited a discharge capacity of 80 mA h g(-1) at 0.1 C rate.
