非水系二次電池用電極の製造方法
Document Type and Number:
Japanese Patent JP7011198
Kind Code:
B2
Abstract:
To provide a manufacturing method of an electrode for a non-aqueous secondary battery capable of constructing a non-aqueous secondary battery having excellent safety and cycle characteristics.SOLUTION: A manufacturing method of an electrode for a non-aqueous secondary battery includes the steps of mixing a compound containing lithium, a compound containing nickel, and barium titanate to obtain a mixed raw material, heat-treating the mixed raw material to obtain a first composition containing a lithium transition metal composite oxide, obtaining an electrode composition containing the first composition, a conductive auxiliary agent, and a binder, and applying the electrode composition onto the current collector and pressurizing the electrode composition to form an active material layer having a density of 2.4 g/cm3 or more and 3.6 g/cm3 or less on the current collector.SELECTED DRAWING: None
