“…Furthermore, the structure of the NASICON type-Li 3 Fe 2 (PO 4 ) 3 is more stable than that of olivine-type LiFePO 4 34 and its synthesis is easier as it can be prepared directly in air. NASICON type-Li 3 Fe 2 (PO 4 ) 3 have been commonly synthesized via various methods such as solid-state reactions 35 , hydrothermal 36 , sol-gel combustion 32 and ultrasonic spray pyrolysis 37 . However, there are only limited reports regarding the Li 3 Fe 2 (PO 4 ) 3 film deposited by RF Sputtering 12 .…”

The increasing demands from micro-power applications call for the development of the electrode materials for Li-ion microbatteries using thin-film technology. Porous Olivine-type LiFePO 4 (LFP) and NASICON-type Li 3 Fe 2 (PO 4 ) 3 have been successfully fabricated by radio frequency (RF) sputtering and post-annealing treatments of LFP thin films. The microstructures of the LFP films were characterized by X-ray diffraction and scanning electron microscopy. The electrochemical performances of the LFP films were evaluated by cyclic voltammetry and galvanostatic charge-discharge measurements. The deposited and annealed thin film electrodes were tested as cathodes for Li-ion microbatteries. It was found that the electrochemical performance of the deposited films depends strongly on the annealing temperature. The films annealed at 500 °C showed an operating voltage of the porous LFP film about 3.45 V vs. Li/Li + with an areal capacity of 17.9 µAh cm −2 µm −1 at C/5 rate after 100 cycles. Porous NASICON-type Li 3 Fe 2 (PO 4 ) 3 obtained after annealing at 700 °C delivers the most stable capacity of 22.1 µAh cm −2 µm −1 over 100 cycles at C/5 rate, with an operating voltage of 2.8 V vs. Li/Li + . The post-annealing treatment of sputtered LFP at 700 °C showed a drastic increase in the electrochemical reactivity of the thin film cathodes vs. Li + , leading to areal capacity ~9 times higher than as-deposited film (~27 vs. ~3 µAh cm −2 µm −1 ) at C/10 rate.

“…Recently, much attention has been focused on the phospho-olivine LiMPO 4 (M = Mn, Fe, Co and Ni) family of materials [3,[6][7][8][9][10][11][12]. Good electrochemical performance has been reported for LISICON-type and NASICON-type materials such as A 1+x M 2 (PO 4 ) 3 (A = Li, Na, M = Fe, V, Ti, Nb) [13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Lithium transition metal phosphates suffer from low electrical conductivities and slow Li-ion diffusions that limit their rate capability.…”

“…The Fe 1 -Fe 1 /Fe 2 -Fe 2 interaction has antiferromagnetic coupling and the Fe 1 -Fe 2 interaction is called ferrimagnetic coupling. 8 Figure 1 shows the temperature-dependent ZFC and FC magnetization curves of Li 3 Fe 2 (PO 4 with applied field of 5 T. The curve decreases slowly down to its minimum value at temperature T min of 13 K with increasing temperature and beyond T min , the value remains constant up to maximum temperature T max of 28 K. After T max , the magnetization of curve decreases again. This temperature dependence indicates that Li 3 Fe 2 (PO 4 ) 3 has antiferromagnetic coupling below T min while it has ferrimagnetic coupling between two Fe 1 -Fe 2 sub-lattices with increasing temperature until T max by exchange coupling from Curie-Weiss analysis.…”

Li3Fe2(PO4)3 has been actively studied as a Lithium ion battery cathode material for the next-generation energy storage application. Here, we have investigated the changes of magnetic coupling between two different magnetic sub-lattices in Li3Fe2(PO4)3 with x-ray diffraction (XRD), superconducting quantum interference device (SQUID), and Mössbauer spectroscopy measurements. The experimental XRD pattern was analyzed using Rietveld refinement, confirming single phase. In order to investigate the magnetic property, the SQUID measurement under applied field of 5 T was performed between 4.2 and 295 K. From the temperature-dependent zero-field-cooled and field-cooled magnetization curves, we observed the magnetization decreasing with increasing temperature up to Tmin = 13 K, at which the magnetization showed a minimum value. With continuing increase in temperature, the magnetization starts increasing with a maximum value at Tmax = 28 K and beyond Tmax, the magnetization decreases with the further increase in temperature. Based on the experimentally measured Mössbauer spectra, we identified that the ratios of first and sixth to second and fifth absorption lines were identical around Tmin, while with increasing temperature the area of second and fifth absorption line rapidly decreased up to Tmax. Our study suggests that the spin canting angle between the applied field and hyperfine field of Li3Fe2(PO4)3 is constant up to Tmin. However, the spin canting angle starts decreasing with increasing temperature, reaching a minimum value at Tmax, and beyond Tmax it is increasing. We expect that around Tmax, the ferrimagnetically coupled spin arrangement is appeared to be collinear along the applied field direction under applied field of 5 T.
