Latest Patent Applications

Kazushi Andou has filed several notable patent applications related to nonaqueous electrolyte secondary batteries. One of his applications describes a nonaqueous electrolyte secondary battery where the positive electrode active material consists of a mixture of a lithium-cobalt composite oxide containing both zirconium and magnesium, along with a lithium-manganese-nickel composite oxide that includes both manganese and nickel. The nonaqueous electrolyte in this battery features fluoroethylene carbonate and dimethyl carbonate as solvents, along with an additive capable of forming an SEI surface film, which enhances oxidation resistance. This design aims to suppress the decomposition of the organic solvent, resulting in a battery with a long cycling life, even when charged at high potentials.

Another application focuses on a nonaqueous electrolyte secondary battery that minimizes positive electrode degradation during high-temperature storage in a charged state. This battery includes a positive electrode, a negative electrode, a separator, and a nonaqueous electrolyte containing LiPF and a dinitrile compound represented by a specific chemical formula. The inclusion of magnesium hydroxide further enhances the battery's performance, ensuring superior remaining capacity and discharge characteristics after high-temperature storage.
