“…Though LiMn 2 O 4 prepared by conventional solid state reaction method has the advantage of mass production, the product usually contains some impure phases and oxygen deficiency which is detrimental to its electrochemical performance and also it involves higher preparation temperature with long heating time followed by several grinding and annealing process [3,15,16]. Hence, so far LiMn 2 O 4 and the substituted compounds have been studied by preparation through many different chemical methods like sol-gel [17,18], ultrasonic spray pyrolysis [3,19], sucrose aided combustion [20], spray-drying [21], flame spray pyrolysis [22], rheological phase assisted microwave synthesis [23], hydrothermal method [24], colloidal templating process 0013-4686/$ -see front matter © 2010 Elsevier Ltd.
