Conductive paste and mixture paste for lithium ion battery positive electrode

The present invention provides a conductive paste for positive electrodes of lithium-ion batteries and mixture paste for positive electrodes of lithium-ion batteries that have an easy-to-apply viscosity, even when a relatively small amount of a dispersant is incorporated. More specifically, the present invention provides a conductive paste for positive electrodes of lithium-ion batteries containing a dispersion resin (A), conductive carbon (B), and a solvent (C), the dispersion resin (A) being a copolymer of a monomer mixture comprising a polycyclic aromatic hydrocarbon-containing monomer (A-1) in an amount of 1 to 70 mass%, based on the total solids content. 本发明要解决的问题在于，提供种即使分散剂的配合量比较少也具有容易涂布的粘度的锂离子电池正极用导电浆料和锂离子电池正极用复合材料浆料。本发明提供种锂离子电池正极用导电浆料，其含有分散树脂(A)、导电碳(B)和溶剂(C)，其中，所述分散树脂(A)是通过将单体混合物进行共聚来得到，以固体成分的总量为基准，所述单体混合物含有1质量％至70质量％的具有多环芳烃的单体(A-1)。
