Nanocomposites of Sn and Li[sub 2]O Formed from the Chemical Reduction of SnO as Negative Electrode Material for Lithium-Ion Batteries

Abstract

A nanocomposite of lithium oxide and tin was prepared by reducing with through a powder milling process. The tin particles were found to be uniformly distributed within a lithium oxide matrix with the majority of tin particles on the order of or less. The nanocomposite was evaluated as an electrode material. Most of the irreversible capacity on the first cycle associated with electrodes was eliminated. ©2000 The Electrochemical Society
