LITHIUM-MANGANESE DOUBLE OXIDE, ITS PRODUCTION AND USE

摘要

PURPOSE:To provide a lithium-manganese double oxide useful as a positive electrode material of a lithium secondary battery having high working range, large discharging capacity and cycling stability, its production process and a lithium secondary battery having high output and high energy density and produced by using the lithium-manganese double oxide as the positive electrode. CONSTITUTION:This lithium-manganese double oxide has a spinel structure composed of Li, Mn and 0 and is expressed by the formula LixMn2Oy [1.0
