Preparation of iron phosphate cathode material of Li3Fe2(PO4)3 by hydrothermal reaction and thermal decomposition processes

Study on synthesis routes and their influences on chemical and electrochemical performances of Li3V2(PO4)3/carbon

“…Recently, considerable studies have been performed to the lithium conducting phosphates such as LiFePO 4 [1][2][3][4][5][6], LiCoPO 4 [7][8][9], LiMnPO 4 [10][11][12][13], Li 3 V 2 (PO 4 ) 3 [14][15][16][17][18][19][20][21][22][23], etc. These materials contain both mobile Li + ions and redox-active metals within a rigid phosphate network, and display remarkable electrochemical and thermal stability as well as comparable density.…”

Olivine-Based Cathode Materials

“…The carbon coating, *2-nm thick was realized using the lactose route applied. Then, the voltage was varied at the rate 1.25 mV per minute, as shown in the figure: a voltage increase up to 4 V is followed by a decrease to 2.2 V and an increase again up to 3.2 V. Besides the peak associated with Fe 2+ , the part of the curve obtained by decreasing the voltage shows a secondary peak at 2.63 V that is characteristic of the Fe 3+ in iron oxide (vs. more than 3.5 V in phosphate) [32]. The presence of Fe 3+ ions in LFP samples confirms the delithiation of the surface layer evident in the previous sections.…”

Polyanionic Compounds as Cathode Materials

“…Among the various synthesis approaches pursued in the past few years, the hydrothermal route is particularly successful with respect to controlling the chemical composition and crystallite size [13,[30][31][32][33]. The conventional hydrothermal process involves a reaction time 5-12 h to synthesize LiFePO 4 [34][35][36][37][38][39][40].…”
