| description | The present invention provides a conductive composition for electrodes, which has improved conductivity and dispersibility. Further, the present invention provides a positive electrode for non-aqueous batteries having lower pole plate resistance and an improved binding property and a non-aqueous battery having higher energy density, higher output characteristics and higher cycle characteristics, using the above conductive composition for electrodes. In the present invention, the conductive composition for electrodes comprises: a conductive material containing carbon black and multi-walled carbon nanotubes having a powder resistivity of 0.035 Ω·cm or less as measured under a load of 9.8 MPa and a volume-converted median diameter D50 of from 0.3 to 8 µm, which is a measure of the dispersibility; an active material; a binder; and at least one dispersant. By using the conductive composition and further containing from 3 to 50% by mass of the multi-walled carbon nanotubes in the conductive composition, the positive electrode for non-aqueous batteries having lower pole plate resistance and improved binding property and a non-aqueous battery having higher output characteristics and higher cycle characteristics can be obtained. |
