Popis:	Composites consisting of "active" grains which can alloy with lithium and "inactive" grains which cannot have been made by mechanical alloying of elemental powders. The inactive grains act as a matrix to hold the active grains as they repeatedly alloy with lithium during the operation of a lithium battery. A microscopic mixture of (active) and (inactive) shows a volumetric capacity for which is more than twice that of the graphite materials which are now the anode of choice for the battery. Unlike pure and alloys, the composite retains this capacity for many charge‐discharge cycles suggesting that materials like this will be the anodes of choice for the next generation of compact, high energy, batteries. ©1999 The Electrochemical Society
