Title:
リチウムイオン二次電池正極用スラリー、リチウムイオン二次電池正極用スラリーの製造方法、およびリチウムイオン二次電池用正極の製造方法
Document Type and Number:
Japanese Patent JP6601391
Kind Code:
B2
Abstract:
Provided is a slurry for lithium ion secondary battery positive electrode-use that includes a positive electrode active material, a binding material, a conductive material, and an organic solvent. The positive electrode active material is a lithium cobalt-based composite oxide particle having an oxide of at least one metal selected from the group consisting of Mg, Ca, Al, B, Ti, and Zr on its surface. The binding material includes a polymer (P1) and a fluorine-containing polymer (P2). The polymer (P1) includes a nitrile group-containing monomer unit, a (meth)acrylic acid ester monomer unit, and an alkylene structural unit having a carbon number of at least 4, and does not substantially include a hydrophilic group-containing monomer unit.
