摘要

A positive electrode material for a lithium ion polymer battery capable of improving the positive electrode density while suppressing the peeling of the carbonaceous film covering the surface of the primary particles of the positive electrode active material, ensuring electronic conductivity, and a lithium ion containing the positive electrode material for the lithium ion polymer battery A lithium ion polymer battery comprising a positive electrode for a polymer battery and the positive electrode for a lithium ion polymer battery is provided. The positive electrode material for a lithium ion polymer battery of the present invention is _{an active material particle comprising a central particle represented by the general formula LixAyDzPO 4} and a carbonaceous film covering the surface of the central particle, and comprises an active material particle, an ion conductive polymer, and a conductive aid. A mixture having a mixing ratio of 66:30:4 in a mass ratio is dissolved in a solvent, and the viscosity of a paste having a total solid content of 40 mass% is 4.0 [1/s] and a viscosity of 5000 mPa·s or less.
