Li3Fe2(PO4)3 solid electrolyte prepared by ultrasonic spray pyrolysis

Porous NASICON-Type Li3Fe2(PO4)3 Thin Film Deposited by RF Sputtering as Cathode Material for Li-Ion Microbatteries

“…NASICON has also a relatively high ionic conductivity resulting from the disorder of lithium ions in the structure, favorable redox properties, low cost, structural stability, and simple fabrication procedures [5, 6, 12]. Many methods have been reported to synthesize Li 3 Fe 2 (PO 4 ) 3 nanostructures such as hydrothermal [13, 14], gel combustion [15], solid state [16–19], solution with the use of citric acid [20], sol-gel [21], ultrasonic spray combustion [22], and ion exchange with molten salt [23, 24]. …”

Optical characterization of SnO2:F films by spectroscopic ellipsometry

“…Ultrasonic spray pyrolysis (USP) technique includes an ultrasonic atomizer which is connected to an oscillator. This ensures the solution to be sprayed with better atomizing using ultrasonic waves, and these results in decreasing of droplet size and production of more homogeneous materials [35,36].…”

Selective Synthesis of Lithium Ion‐Conductive β‐LiVOPO4 Crystals via Glass–Ceramic Processing

“…That is, Li + ion conductivities in the glass–ceramics would be affected by the presence of grain boundaries. The following activation energies for the electrical conductivity in other lithium iron‐conductive materials being potential candidates for cathode and electrolyte materials in lithium ion batteries have been reported: E a =0.50 eV for LiFePO 4 , 26 E a =0.48 eV for γ‐Li 3 Fe 2 (PO 4 ) 3 , 27 and E a =0.48∼51 eV for the glass–ceramics consisting of Nasicon‐like Li 3 Fe 2 (PO 4 ) 3 8 . It should be emphasized that the activation energy of E a =0.38 eV in the glass–ceramics with β‐LiVOPO 4 crystals is small compared with those lithium ion‐conductive materials.…”
