Latest Patents
Sugibuchi holds a patent for a treatment process for a positive electrode active material for lithium-ion secondary batteries. This process involves the removal of lithium compounds, such as LiCO and LiOH, that are present in the positive electrode active material but are unsuitable for use. The method ensures that when the resultant lithium compound is utilized as a positive electrode material, the discharge capacity and average discharge voltage of the secondary battery remain stable. Additionally, the process prevents gelation caused by cleaning treatments. The positive electrode active material is cleaned using a fluid containing NH, followed by solid-liquid separation, and the solid component is calcined at temperatures between 600 to 700°C in an oxygen atmosphere. The cleaning fluid is characterized by a conductivity of 11.6 mS/cm or less and can be reused, enhancing the efficiency of the process.
