Latest Patents

Takimoto's latest patents include a process for producing lithium vanadium phosphate-carbon composite. This innovative process involves several steps, starting with mixing a lithium source, a tetravalent or pentavalent vanadium compound, a phosphorus source, and a conductive carbon material source in an aqueous solvent. The mixture undergoes a precipitation reaction, followed by wet grinding to obtain a slurry. The slurry is then spray-dried to create a reaction precursor, which is calcined in an inert gas atmosphere or a reducing atmosphere at temperatures between 600 to 1300°C. The resulting lithium vanadium phosphate-carbon composite is designed to provide excellent battery performance, particularly as a cathode active material.

Another notable patent by Takimoto is a positive-electrode material that consists of lithium vanadium phosphate particles. These particles have an average primary particle diameter ranging from 0.3 µm to 2.6 µm and crystallite sizes between 24 nm and 33 nm. The lithium vanadium phosphate particles are coated with conductive carbon, enhancing their performance in battery applications.
