POSITIVE ELECTRODE MATERIAL FOR LITHIUM ION POLYMER BATTERY, POSITIVE ELECTRODE FOR LITHIUM ION POLYMER BATTERY, AND LITHIUM ION POLYMER BATTERY

摘要

The positive electrode material for a lithium ion polymer battery of the present invention is active material particles including core particles represented by General Formula Li_xA_yD_zPO₄ and the carbonaceous film that coats surfaces of the core particles, wherein a paste including the active material particles has a viscosity of 5, 000 mPa·s or less when a viscosity of the paste is measured at a shear rate of 4.0 [1/s], wherein the paste is a mixture of the active material particles, an ion-conductive polymer, a conductive auxiliary agent and a solvent, in which the active material particles, the ion-conductive polymer and the conductive auxiliary agent are included in the paste in a mass ratio of 66:30:4, and a total solid content of the paste is 40% by mass.
