| description | Provided is a conductive composition for electrodes, the conductive composition having excellent electrical conductivity and dispersibility. Also provided are: a positive electrode for non-aqueous batteries, the positive electrode using the conductive composition and having low electrode plate resistance and excellent binding properties; and a non-aqueous battery having high energy density, high output characteristics, and high cycle characteristics. The conductive composition for electrodes contains a conductive material, an active material, a binder, and a dispersant, wherein the conductive material contains carbon black and a multi-walled carbon nanotube having a powder resistivity of 0.035 Ω⋅cm or less as measured under a load of 9.8 MPa, and a median volumetric diameter D50 value, which is as a measure of dispersibility, in the range of 0.3-8 μm The positive electrode which is for non-aqueous batteries and has low electrode plate resistance and excellent binding properties; and the non-aqueous battery having high output characteristics and high cycle characteristics are obtained by using the conductive composition in which the content of the multi-walled carbon nanotube in the conductive material is 3-50 mass %. |
