Synthesis and characterization of carbon-coated LiMnPO4 and LiMn1−xFexPO4 (x=0.2, 0.3) materials for lithium-ion batteries

High rate capability and cycle performance of Ce-doped LiMnPO 4 /C via an efficient solvothermal synthesis in water/diethylene glycol system

“…However, its intrinsically low electronic conductivity and slow lithium ion diffusion have limited the commercial applications of LiMnPO 4 [5,6]. Many attempts have been made to solve these problems such as particle size reduction [7,8], carbon coating [9,10], substitution doping [6,11] and so on.…”

“…Some metal ion dopants, such as Mg 2+ [12], Cu 2+ [13], Fe 2+ [11], Cr 3+ [14] and Zr 4+ [15] etc., have been studied in detail to improve the electrochemical performance of LiMnPO 4 . Shiratsuchi et al [16] reported that Mg doping was effective in increasing the rate capability of LiMnPO 4 .…”

Effects of High Energy Milling on the Carboncoated Lithium Iron Phosphate Precursor Nature

“…At the same time, it fully mixed materials so that it promoted the carbon-thermal reduction reaction. The precursor, produced by mixing lithium source, phosphorus source, iron source and carbon source, was heated in inert atmosphere and finally became carbon-coated LFP cathode material [13] . The performance of the sample will be better with the morphology becoming more uniform and the particle size decreasing [14,15,16] .…”

Electrochemical performance of LiFe1−xMnxPO4/C materials prepared by ball milling

“…14 To utilise its inherent high capacity, some attempts have been made to synthesise mixed olivine phosphates of LiFe 12x Mn x PO 4 where the amounts of Mn can be manipulated in a desirable proportion. [15][16][17] In the present work, LiFe 12x Mn x PO 4 /C composite materials as cathode materials in Li-ion batteries have been synthesised and their electrochemical properties have been investigated. The olivine structure of the LiFe 12x Mn x PO 4 /C composite was obtained.…”
