    摘要： This carbon nanofiber is produced by a vapor phase reaction of a carbon oxide-containing raw material gas using a metal oxide powder including a Co oxide as a catalyst, wherein at least one type selected from metal cobalt, carbon-containing cobalt metals, and cobalt-carbon compounds is contained (encapsulated) in the fiber in a wrapped state. This method for producing a carbon nanofiber includes: producing a carbon nanofiber by a vapor phase reaction of a carbon oxide-containing raw material gas using a mixed powder of a Co oxide and a Mg oxide as a catalyst, wherein a mixed powder of CoO and MgO, which is obtained by hydrogen-reducing a mixed powder of Co 3 O 4 and MgO using a reduction gas having a hydrogen concentration in which metal cobalt is not generated, is used as the catalyst.

    摘要： Disclosed is a positive electrode forming material for a positive electrode of a battery, the material including particles of a positive electrode active material and fine carbon fibers adhering to surfaces of particles of the positive electrode active material in a shape of a network. The positive electrode active material is preferably fine particles having an average particle diameter of 0.03 to 40 µm. Each of the fine carbon fibers is preferably carbon nanofiber having an average fiber diameter of 1 to 100 nm and an aspect ratio of 5 or greater. The carbon nanofiber is surface-oxidized. The positive electrode forming material includes a binder. The content of the fine carbon fibers is 0.5 to 15 parts by mass and the content of the binder is 0.5 to 10 parts by mass with respect to 100 parts by mass of the positive electrode active material.
