<P>PROBLEM TO BE SOLVED: To improve battery performance of a battery using a battery composition including a conductive assistant, which is dispersed stably without impeding conductivity of the conductive assistant. <P>SOLUTION: The battery composition contains: a dispersant of one kind or more selected from an organic pigment derivative having aromatic hydroxyl group or aromatic thiol group, or triazine derivative having aromatic hydroxyl group or aromatic thiol group; a solvent; a binder; and a positive electrode active material or a negative electrode active material. The lithium secondary battery includes: a positive electrode having a positive electrode mixture layer on a current collector; a negative electrode having a negative electrode mixture layer on the current collector; an electrolyte containing lithium; and as required an electrode foundation layer. The positive electrode mixture layer, the negative electrode mixture layer or the electrode foundation layer uses the battery composition to form the lithium secondary battery. <P>COPYRIGHT: (C)2010,JPO&INPIT |
