Sucrose-aided combustion synthesis of nanosized LiMn1.99−yLiyM0.01O4 (M=Al3+, Ni2+, Cr3+, Co3+, y=0.01 and 0.06) spinels

Microwave-assisted optimization of the manganese redox states for enhanced capacity and capacity retention of LiAlxMn2−xO4 (x = 0 and 0.3) spinel materials

“…[1][2][3][4][5][6][7][8] Perhaps, the lithium manganese oxide, LiMn 2 O 4 (LMO) spinel material needs little or no introduction as it has proved itself as one of the most attractive cathode materials for RLIBs due to its high operating voltage (4 V), low cost, environmental compatibility, and stability at low temperature compared to other cathode materials.…”

Synthesis of compounds, Li(MMn11/6)O4 (M=Mn1/6, Co1/6, (Co1/12Cr1/12), (Co1/12Al1/12), (Cr1/12Al1/12)) by polymer precursor method and its electrochemical performance for lithium-ion batteries

“…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.

Synthesis of LiFe0.4Mn0.6−x Ni x PO4/C by co-precipitation method and its electrochemical performances

“…during the charge-discharge process [13][14][15]. In the case of LiMn 2 O 4 , doping other elements is an effective method to suppress the Jahn-Teller transition and many kinds of doping ions have been investigated [16][17][18][19][20][21][22]. In this study, nickel is chosen as a doping element considering its ability of forming a phosphate solid solution with LiFePO 4 and LiMnPO 4 [23].…”
