Kinetics investigation of a preferential (104) plane oriented LiCoO2 thin film prepared by RF magnetron sputtering
چکیده انگلیسی

LiCoO2 thin films with a preferential (104) orientation were prepared on Au substrates by radio frequency magnetron sputtering. The Li–ion chemical diffusion coefficients D˜Li were measured by cyclic voltammetry (CV), galvanostatic intermittent titration technique (GITT), potentiostatic intermittent titration technique (PITT), and electrochemical impedance spectroscopy (EIS). The D˜Li values depended on the content of Li in Li1−δCoO2. The D˜Li values by GITT and PITT were in the range of 10− 10–10− 12 cm2 s− 1 and 10− 11–10− 12 cm2 s− 1, respectively, and those by EIS varied over a more wide rang of from 10− 9 to 10− 12 cm2 s− 1. It was found that the D˜Li values from different methods showed thickness independent. The D˜Li values from different methods were compared with those reported previously.
