Elevated Temperature Cycling Stability and Electrochemical Impedance of LiMn₂O₄ Cathodes with Nanoporous ZrO₂ and TiO₂ Coatings

In this study, nanoporous zirconia (ZrO2) and titania (TiO2) coatings are shown to stabilize the cycling performance of lithium-ion batteries with LiMn2O4 spinel cathodes. The effect...

The Electrochemical Stability of Spinel Electrodes Coated with ZrO₂, Al₂O₃, and SiO₂ from Colloidal Suspensions

Stoichiometric LiMn2O4 and substituted Li1.05M0.05Mn1.9O4 (M=Al,Ni) spinel electrodes, coated with ZrO2, Al2O3, and SiO2 from colloidal suspensions, have been evaluated in lithium cells. ZrO2-coated Li1.05Ni0.05Mn1.9O4...
