Abstract

Nanostructured lithium manganese oxide with spherical particles was synthesized via ultrasonic spray pyrolysis technique. The material shows a pronounced stability upon prolonged cycling at room temperature at high charge-discharge rates up to 10C. The electrochemical performance of the cell at elevated temperature was remarkably improved by addition of AlPO 4 to the electrolyte. The AC impedance spectroscopy study showed the interface stabilization by the AlPO 4 additives and the suppression of the interface impedance development upon prolonged cycling.
