Semester 3 Characterization: Raman Spectroscopy
From the above chart it is clear that the material synthesized was not LiPO4. The XRD done later confirms this.
Characterization: X-Ray Diffraction

• Nanomaterial synthesized
• <d> 100 to 300 nm in width
• Particles are rod shaped.
• Homogenous.
• Particles length > 1µ
Characterization TGA- Of Sample
Characterization: Differential Scanning Calorimetry
Differential Scanning Calorimetry was carried out on the sample. The following was observed:
• Dip in the 50 to 200 range for the dehydration process. This confirms the initial TGA plot
• Change at the higher temperatures due to transformation of FePO4 from amorphous to crystalline phase
Electrode Manufacture:
Batteries Manufacture:
Conduction and capacity testing.
Conclusion:
Thus, during the course of this project we attempted to synthesize Lithium Iron Phosphate nanomaterial. The aims of the project was to arrive at particles that had the following desirable properties:
• Even Size Distribution Homogenous particles.
• Lithium Iron Phosphate Material
• Nanodimensional Material Size
• Rod like Shape
• Low cost Method – Solvothermal
