Growth of FePO4 nanoparticles on graphene oxide sheets for synthesis of LiFePO4/graphene

3D graphene aerogel framework enwrapped LiFePO4 submicron-rods with improved lithium storage performance

“…As shown in Fig. 2b, LFP displays the band at about 950 cm −1 , which can be attributed to the symmetric PO4 3− stretching vibration [42]. Meanwhile, GO exhibits the obvious vibrational peaks at around 1360 and 1590 cm -1 , respectively ascribed to the D-band which represents the disorders/defects in the graphite structure and G-band which indicates the presence of graphite carbon) [41].…”

LiFePO4/C twin microspheres as cathode materials with enhanced electrochemical performance

“…The carbon content in LFP/C-0, LFP/C-60, LFP/C-100 was calculated to be 1.75 wt%, 2.64 wt% and 4.87 wt%, respectively, according to Formula (2) . 35 LiFePO 4 + 1/4 O 2 = 1/3 Li 3 Fe 2 (PO 4 ) 3 + 1/6 Fe 2 O 3 % carbon = theoretical weight gain of LiFePO 4 − total weight gain of the composites …”

“… 26 Li and his colleagues connected Fe 2+ and carbon nanotubes through the special functional groups of phytic acid to form a three-dimensional network around LiFePO 4 particles, which improved the conductivity and ion transport capacity of LiFePO 4 /C composites. 35 But these works often used a large amount of inorganic carbon materials such as graphene and carbon nanotubes, while too much carbon content reduced the tap density of materials. Therefore, we preferred to use a simple hydrothermal method to prepare LiFePO 4 /C composites with low carbon content and high tap density, to achieve excellent electrochemical performance improvement through microstructure adjustment.…”

The Effect of Reduced Graphene Oxide (rGO) Coating on Electrical Conductivity of Lithium Ferro Phosphate (LFP) as an Alternative Cathode for Li-Ion Battery

“…Similarly, Arifin et al, have successfully prepared LiFePO4-based rGO composites using the hydrothermal method [12]. Besides, LiFePO4/graphene composites have been successfully prepared through in-situ solvothermal method [13], solid state [14], a liquid phase method [15], and the spray drying and annealing process [16] successfully. In general, the composite produced from various synthesis methods has significantly improved the electrochemical performance of LiFePO4 electrodes [17].…”
