摘要
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 AlPO4 to the electrolyte. The AC impedance spectroscopy study showed the interface stabilization by the AlPO4 additives and the suppression of the interface impedance development upon prolonged cycling.
