“…10 %), which limit their applications in high power batteries [10]. Similar to LiFePO 4 , many efforts have been investigated to overcome these obstacles of the LiMnPO 4 by minimizing the particle size [11][12][13][14], applying conductive surface coatings [15][16][17][18], doping with metal ions [9,[19][20][21][22], and so on.…”

A porous LiFe 0.4 Mn 0.6 PO 4 /C composite was prepared via a simple carbon gel-combustion synthesis process. The obtained product possessed higher surface area, abundant mesopore structure, the improved kinetics and electronic conductivity by doping with Fe 2+ and coating with carbon, respectively. As a cathode material for lithium-ion batteries, the as-prepared LiFe 0.4 Mn 0.6 PO 4 /C composite showed outstanding rate capacities and cycling performances at high charge/ discharge rates. The discharge capacity of LiFe 0.4 Mn 0.6 PO 4 /C was as high as 121.1 mAh g −1 in the first cycle at 0.5 C and remained 103.8 mAh g −1 after 50 cycles. Even at higher rate of 10 C, the initial discharge capacity of the electrode exhibited 64.6 mAh g −1 , and the sample electrode delivered capacity retention of 83.3 % after 1000 cycles. The improved electrochemical properties of the LiFe 0.4 Mn 0.6 PO 4 /C electrode materials suggest the applications of the sample in high power lithium-ion batteries.

“…Nanosized LiMnPO 4 provides the shorter lithium ion diffusion path within a single particle compared to micronsized LiMnPO 4 [16]. Most highly performing LiMnPO 4 materials were achieved by adding a large amount of carbon (15-30 wt%) in order to increase the electronic conductivity [12][13][14][15][17][18][19][20].…”

“…Nano-LiMnPO 4 has been prepared by various wet chemical methods such as hydrothermal [21][22][23], thermal decomposition [20,24], solvothermal [17,25], polyol methods [15], etc. Wet chemical methods are preferable as they allow perfect mixing of precursors, better homogeneity and more regular morphology to obtain nanosized particles.…”

5-10 nm thin rod shaped LiMnPO 4 nanoparticles are synthesized by an improved thermal decomposition method. The synthesis parameters such as the concentration of surfactants, reaction temperature and time, as well as the presence of a solvent play a critical role in the formation of spherical, thin or thick nanorods, and needle-shaped particles of LiMnPO 4 . A washing procedure to efficiently eliminate the surfactants attached to the surface of LiMnPO 4 nanoparticles is presented, avoiding thermal treatment at high temperatures. A nanocomposite LiMnPO 4 electrode provides a discharge capacity of 165 mAh/g at 1/40 C and 66 mAh/g at 1 C with only 10 wt% of total carbon additive. The characteristics of as-synthesized and low amount of carbon coated LiMnPO 4 are described as well as their electrochemical properties.

“…Among these adopted methods, hydrothermal [15][16][17][18][19][20][21][22] and solvothermal [23][24][25][26][27][28][29][30][31][32][33][34][35] methods have been widely investigated because it is easy to control the morphology and minimize the particle size. Dokko [15] prepared LiMnPO 4 /C by the hydrothermal method at 190 C for 12 h. The prepared samples exhibited 135 mAhÁg À1 at 0.01C.…”
