Several synthesis techniques can be used to produce nanostructured LiFePO4. These include: 1. Sol-Gel Method: This technique allows for precise control over particle size and distribution. 2. Hydrothermal Synthesis: This method is useful for producing highly crystalline nanoparticles with uniform size. 3. Spray Pyrolysis: This allows for the continuous production of nanoparticles and is scalable for industrial applications.
