title: Enhanced cycleability of LiMn2O4 cathodes by atomic layer deposition of nanosized-thin Al2O3 coatings.
abstract: This report is the first effort to use atomic layer deposition method for deposition of nanosized-thin and highly conformal Al(2)O(3) coatings onto LiMn(2)O(4) cathodes with precise thickness-control at atomic scale. The coated cathodes exhibit significantly enhanced cycleability than bare cathodes, as the dense ALD coating protects the cathode material from severe dissolution.
