Title: Dajun Liu: Innovator in Lithium-Ion Battery Technology
Introduction
Dajun Liu is a prominent inventor based in Anhui, China. He has made significant contributions to the field of lithium-ion battery technology. With a total of 2 patents, Liu's work focuses on enhancing the performance and efficiency of battery materials.
Latest Patents
One of Liu's latest patents discloses a method for preparing a LiNbTiO/C nanocomposite as anode material for lithium-ion batteries. This method includes several steps: obtaining a mixture of a lithium salt, niobium pentaoxide, titanium dioxide (TiO), and a carbon source in a selected stoichiometric ratio; mixing the mixture in a dispersant to produce a slurry; drying the slurry to create a dried mixture; and treating the dried mixture under a protective atmosphere according to a specific heating program. The heating program involves calcining the dried mixture at 600°C for 2-6 hours, heating it at a rate of 2-20°C per minute to 950-980°C, cooling it naturally to 800-850°C, maintaining that temperature for 16 hours, and finally cooling it to room temperature.
Another patent involves a synthesis strategy toward microspheric carbon-coated off-stoichiometric lithium-iron-phosphorus compound materials. This cathode active material is represented by the formula LiFePO/C, where specific stoichiometric conditions are maintained. The materials may consist of double-carbon-coated particles obtained by carbon coating a mixture of a lithium component and FePO/C sub-particles.
