| description | PROBLEM TO BE SOLVED: To provide a conductive paste for preparing a positive electrode of a lithium ion secondary battery, which includes a dispersant capable of uniformly dispersing a conductive material in a positive electrode mixture and does not become a factor of an increase in battery internal resistance.SOLUTION: A conductive paste provided by the present invention includes a conductive material, a dispersant, and an organic solvent. The dispersant is one or two or more organic compounds. The dispersant is one or two or more organic compounds having such properties that the organic compounds are not substantially dissolved with respect to a nonaqueous electrolyte included in a lithium ion secondary battery, the organic compound being one or two or more selected from among polyacrylamide, polyamide, and polystyrene sulfonate.SELECTED DRAWING: Figure 1
【課題】正極合材中で導電材を均一に分散させ得る分散剤であり、且つ、電池内部抵抗の増大の要因とはならない分散剤を含む、リチウムイオン二次電池の正極作製用導電ペーストを提供する。【解決手段】本発明によって提供される導電ペーストは、導電材と、分散剤と、有機溶媒とを含み、該分散剤が、リチウムイオン二次電池に備えられる非水電解液に対して実質的に溶解しない性質の１種または２種以上の有機化合物であり、ここで該有機化合物は、ポリアクリルアミド、ポリアミドおよびポリスチレンスルホン酸のうちから選択される１種または２種以上である。【選択図】図１ |
