Synthesis and characterization of spinel LiMn2O4 for lithium secondary battery

Enhancement of the electrochemical properties of LiMn2O4 through Al3+ and F− co-substitution

“…This leads to the possibility of using fluorine as a method for controlling the morphology and particle size. A regular morphology is very important to both the high spe- cific capacity and the good cyclability of the materials [19,20]. Fig.…”

The Sintering Temperature Effect on Electrochemical Properties of LiMn2O4

“…The higher initial capacity of the LiMn 2 O 4 sintered at lower temperature in Table 3 was attributed to the increased surface area contacted with the electrolyte. Jang et al 23 reported similar results showing better discharge capacity from small and uniform particles. Momchiov et al 24 also reported that the heat treatment temperature changed the total surface area of the particles and affected the electrochemical properties of LiMn 2 O 4 .…”

“…The specific surface area is an important parameter in determining the electrochemical properties of LiMn 2 O 4 because the particle surface is a gateway for Li ion transfer during the charge-discharge cycles and for Mn dissolution. 23,24 Electrochemical Properties. The performance of the LiMn 2 O 4 particles sintered at different temperatures was examined by repeating the charge-discharge cycles 50 times in the range of 3.5-4.5 V at 0.5 C at room temperature.…”

Preparation and electrochemical properties of LiMn2O4 by the microwave-assisted rheological phase method

“…Such kind of morphology is very important to both the high specific capacity and good cycleability of the materials [16][17][18]. Fig.…”
