Solution combustion synthesis of LiMnPO4/C cathode material: The effect of four fuel sources on the electrochemical performances

One-pot coating of LiCoPO4/C by a UiO-66 metal–organic framework

“…[3][4][5] In the family of LiMPO 4 olivines, the voltage of the redox pair equals 3.4 V, 4.1 V, and 5 V for M ¼ Fe, Mn, Co correspondingly. [6][7][8][9] The corresponding specic energy ranges from 578 W h kg À1 for LiFePO 4 to 802 W h kg À1 for LiCoPO 4 . 10,11 However, the practical use of high-voltage materials faces two serious difficulties.…”

Sucrose-Assisted Solution Combustion Synthesis of Doped Strontium Ferrate Perovskite-Type Electrocatalysts: Primary Role of the Secondary Fuel

“…As an additional advantage, in most cases, the use of sucrose allows the combustion reaction to occur without adding ammonia as a pH regulator, which is necessary in the case of traditional citric acid fuel [13]. However, sucrose-assisted combustion has also some drawbacks:The amount of residual carbon is large and the excessive increase in the volume of the light-weight as-burned powder causes powder loss outside of the reaction vessel [2].PEG, a multifunctional polyether compound, is another eco-friendly fuel, often used, alone or mixed with other organics, as a structure-directing agent and/or solvent in sol-gel synthesis [15][16][17][18]. It has been found that the variation of its molecular weight (MW) can modulate the microstructure and porosity development of the produced material [16,[18][19][20].The mixed-fuels approach in SCS was demonstrated to positively affect the electrocatalytic performance of perovskite-type materials in the oxygen reduction up to an order of magnitude [5,[21][22][23].…”

Modeling and synthesis of carbon-coated LiMnPO4 cathode material: Experimental investigation and optimization using response surface methodology

“…The synthesis process was also considered a direct approach to achieving desired performances. For this reason, several methods have been applied to prepare LiMnPO4 with high purity, such as spray-pyrolysis [22,27], sol-gel method [28,29], hydrothermal synthesis [30][31][32][33], precipitation method [34,35] and solution combustion process [36,37]. Among all these methods, some selected ones offer more advantages such as morphology control, better homogeneity, submicron-sized particles, and larger specific surface area with increased electrochemical performances [38,39].…”
