摘要：

Thin films of Li7La3Zr2O12 were deposited on SrTiO3 (100) and Sapphire (0001) substrates at room-temperature using a pulsed-laser-deposition technique. Detailed structural, compositional, optical, and electrochemical characterizations of the films were performed. The films deposited at room-temperature had amorphous structure, and exhibited a lithium-ion conductivity of 3.35 x 10(-7) S/cm. The effects of thermal annealing and pulsed laser annealing on the properties of the films were investigated. Pulsed laser annealed films were found to have a superior lithium-ion conductivity value of 7.36 x 10(-7) S/cm. Moreover, the Li7La3Zr2O12 films were found to be electrochemically stable against lithium metal. (C) 2012 The Electrochemical Society. [DOI: 10.1149/2.013206ssl] All rights reserved.
