Glucose-Assisted Synthesis of Highly Dispersed LiMnPO 4 Nanoparticles at a Low Temperature for Lithium Ion Batteries

Effect of Magnetic Field and Aggregation on Electrical Characteristics of Magnetically Responsive Suspensions for Novel Hybrid Liquid Capacitor

“…In addition, as the liquid sensor senses the electric current and voltage generated through the application of a normal or shear force, the applied electric charge can also be stored in the inner part of the sensor if the liquid undergoes an oxidation-reduction reaction or if the electrodes have an electric double layer. Studies on the electric charge stored in suspensions or polymer liquids have been conducted on lithium ion batteries [34] in which particle dispersion causes aggregation of carbon [35][36][37], TiO 2 [38], and cobalt ferrite [39]. They often have an electrolyte base of polymer [40], ionic liquid [41,42], or ionic liquid crystal [43].…”

Deep Eutectic Solvent Synthesis of LiMnPO4/C Nanorods as a Cathode Material for Lithium Ion Batteries

“…Additionally, the HR-TEM image also clearly showed that the primary LiMnPO 4 particles were coated by a thin carbon layer (approximately 3 nm). This thin carbon layer favors the inhibition of the growth of crystal and reduces the agglomeration of the particles [21,33,70], which have been proved by the results in Figure 4e,f. In addition, the LiMnPO 4 /C crystallites were connected directly with the thin carbon layer to form an excellent conducting network, which could effectively enhance the electronic conductivity of LiMnPO 4 /C and further improve its capability rate [12,69].…”

“…Therefore, many approaches have been carried out to prepare LiMnPO 4 /C with nano-size and nanostructure [ 30 , 31 , 32 ]. In these adopted approaches, hydrothermal/solvothermal methods have attracted particular attention owing to the controllable synthesis of LiMnPO 4 /C with a special morphology [ 2 , 20 , 21 , 33 , 34 , 35 ]. Therefore, various special morphologies such as nanoplates [ 16 , 21 , 36 ]; nanorods [ 10 , 33 , 35 ]; nanosheets [ 18 , 37 ]; flower-like nanostructures [ 34 , 38 ]; hemoglobin [ 39 ]; and wedges [ 40 ] were prepared using the hydrothermal/solvothermal method to enhance the electrochemical performance of LiMnPO 4 .…”

Improved electrochemical performance of LiFe0.4Mn0.6PO4/C with Cr3+ doping

“…The electronic conductivity of LiMnPO 4 (<10 À10 S cm À1 ) is much lower in comparison with that of LiFePO 4 ($10 À8 S cm À1 ), 11,12 resulting in a much poorer electrochemical performance. There have been many efforts in recent years to increase the electronic conductivity of LiMnPO 4 by decreasing the particle size, [13][14][15][16] coating with electronically conducting agents, [17][18][19][20][21] or doping with cations such as Mg 2+ , Fe 2+ , Cu 2+ , Co 2+ , Ni 2+ , Ca 2+ and Zn 2+ . [22][23][24][25][26] Decreasing the particle size could reduce the transport distance of electrons and Liions, which can enhance the rate performance.…”
