Case Study

Preparation and Lithium Ion Conduction of Different Lithium Metaphosphate Based Systems

Money B K, et al. Applied Physics A, 2007, 88, 647-652.

Several different lithium metaphosphate systems (including crystalline LiPO3, glassy phase (Li2O-P2O5), glass-ceramic (LiPO3) and polymer-metal salt complex (PEO)6:LiPO3) were prepared and the transport of lithium ions in them was compared. The results showed that the best lithium ion conduction was observed in the glassy network, followed by glass-ceramic and crystalline phases.
Preparation of lithium metaphosphate systems
· Polycrystalline lithium metaphosphate (LiPO3) was produced by mixing reagent-grade lithium carbonate (Li2CO3) and ammonium dihydrogen phosphate (NH4H2PO4) with a mortar and pestle and heating the mixture in a platinum crucible at 300 ◦C for 4 hours to eliminate NH3, H2O, and CO2, and the sample was maintained at 560 ◦C for 48 hours.
· Mol% 50Li2O-50P2O5 glass synthesized by melt-quenching process. Single-phase glass-ceramic LiPO3 obtained by controlled heat treatment of mol% 50Li2O-50P2O5.
· The creation of the polymer-metal salt complex involved utilizing the solution casting method, where PEO (poly ethylene oxide) and crystalline LiPO3 were dissolved in acetonitrile as a common solvent, mixed thoroughly using a magnetic stirrer for about 24 hours to achieve a homogeneous blend. The resulting uniform, viscous solution was poured into a clean PTFE (poly tetra fluoro ethylene) petri dish and positioned in a vacuum oven maintained at 50 ◦C to eliminate any remaining solvent in the solution. After approximately 48 hours, a fully dried, standalone polymer electrolyte film with a thickness of around 150 µm was obtained.

Ammonolysis of Lithium Metaphosphate Melts

De Souza J E, et al. International Journal of Applied Glass Science, 2020, 11(1), 78-86.

Metaphosphate glasses such as lithium metaphosphate incorporate nitrogen in the molten state under a flow of NH3. After nitridation, the glasses exhibit improved properties such as increased operating range, chemical durability, and ionic conductivity.
Ammonolysis procedure
· The LiPO3 glass underwent nitridation through melting under a constant flow of ammonia for a predetermined duration. The experimental setup for ammonolysis utilized a tube furnace, featuring regulated flows of N2 and/or anhydrous NH3.
· As the temperature was gradually increased from room temperature to the target melting point, a flow of N2 (290 ± 20 mL/min) was maintained. Once the temperature stabilized at either 750 or 780°C, the ammonia flow (160 ± 40 mL/min) was initiated for a specified period. During the nitridation process, the N2 flow was halted.
· In the final phase, the ammonia flow was discontinued to facilitate the cooling of the liquid while maintaining the initial N2 flow rate. Careful temperature regulation ensured that it did not exceed 800°C, which would cause rapid ammonia decomposition.
· The effects of different processing times and the quality of powder and/or bulk material on the nitrogen content of the resulting LiPON glasses were investigated. Throughout the ammonolysis process, base MPO3 glasses, whether in powder or bulk form, were positioned on a vitreous carbon boat located in the approximately 20 cm long uniform temperature zone at the center of the tube furnace.
