Effect of Li Addition on Structural, Electrical and Electrochemical Properties
Lanthanum Manganite. — The incorporation of 10% Li into the A-site of the
25- 009 of
LaMnO3 perovskite effectively enhances its conductivity from 0.25 Ω-1cm-1 at 27 °C in
the undoped sample to 2.25 Ω-1cm-1 at 27 °C. The addition of more than 10% Li results
in the formation of the LiMn2O4 spinel as a second phase. Cyclic voltammetry and
charge/discharge tests indicate that the sample with composition La0.9Li0.1MnO3 is not
electrochemically active. — (SHIH, F.-Y.; FUNG*, K.-Z.; J. Alloys Compd. 391
