Abstract
Sol-gel coating of Al2O3 and subsequent heat-treatment at 400 degreesC greatly improved structural instability of orthohombic LiMnO2 during electrochemical cycling at 55 degreesC. The coated electrode showed only 2% capacity loss after 50 cycles, which was superior to that of the bare one (35% loss) in its capacity stability. This was attributed to the formation of a protective coating layer, consisting of LiMn1-xAlxO2, only at the particle surface.
