Abstract: When an active material with low ionic conductivity and low electric conductivity is used in a nonaqueous electrolyte secondary battery such as a lithium ion battery, it is necessary to reduce the sizes of particles; however, reduction in sizes of particles leads to a decrease in electrode density. Active material particles of an oxide, which include a transition metal and have an average size of 5 nm to 50 nm, are mixed with an electrolyte, a binder, and the like to form a slurry, and the slurry is applied to a collector. Then, the collector coated with the slurry is exposed to a magnetic field. Accordingly, the active material particles aggregate so that the density thereof increases. Alternatively, the active material particles may be applied to the collector in a magnetic field. The use of the aggregating active material particles makes it possible to increase the electrode density.
