NOVELTY - A non-aqueous electrolyte secondary battery is produced by mixing a paste (A) having positive electrode active material and a first binder (A); and a paste (B) having a conductive material and a second binder (B) to prepare a positive electrode material paste (C).    USE - Production of non-aqueous electrolyte secondary battery used in electronic products, e.g. notebook computers, mobile phones and audiovisual equipment.    ADVANTAGE - Provides a non-aqueous electrolyte secondary battery having a high capacity and excellent characteristics in terms of charge/discharge and cycle life. It improves the way the conductive agent and binder are used and controls the amounts of the conductive agent and binder to attain the high active material density of the positive electrode.    DETAILED DESCRIPTION - Production of a non-aqueous electrolyte secondary battery comprises:    (a) mixing a positive electrode active material comprising a lithium-containing transition metal oxide, a first binder A and a dispersion medium to prepare a paste A;    (b) mixing a conductive agent comprising carbon black, a second binder B and a dispersion medium to prepare a paste B;    (c) mixing paste A and paste B to prepare a positive electrode material paste C;    (d) applying the positive electrode material paste C to a positive electrode core, rolling and drying the resultant to prepare a positive electrode; and    (e) fabricating a battery using the positive electrode (2), a negative electrode (3) and a non-aqueous electrolyte. The contact angle theta-A between the non-aqueous electrolyte and the binder A and contact angle theta-B between the non-aqueous electrolyte and the binder B satisfy formula (I).    thetaB-thetaA at least 15 degrees (I)    An INDEPENDENT CLAIM is also included for a non-aqueous electrolyte secondary battery comprising a positive electrode having a positive electrode material layer and a positive electrode core for supporting the positive electrode material layer, where conductive agent in the paste forms agglomerated particles having a bulk density of 0.1-0.5 g/ml; a negative electrode comprising a negative electrode material layer and a negative electrode core for supporting the negative electrode material layer; and a non-aqueous electrolyte comprising a non-aqueous solvent dissolving a lithium salt.
