摘要：

A nanocomposite of lithium oxide and tin was prepared by reducing SnO with Li3N 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 100 nm or less. The nanocomposite was evaluated as an electrode material. Most of the irreversible capacity on the first cycle associated with SnO electrodes was eliminated. (C) 2000 The Electrochemical Society.
