Abstract
[Problems] To provide an electrode material for a lithium-ion rechargeable battery capable of improving the battery characteristics, durability, and stability of a lithium-ion rechargeable battery, an electrode for a lithium-ion rechargeable battery, and a lithium-ion rechargeable battery. [Means] An electrode material for a lithium-ion rechargeable battery of the present invention is an electrode material for a lithium-ion rechargeable battery formed by coating the surface of an electrode active material represented by General Formula LiADPO(here, A represents at least one element selected from Co, Mn, Ni, Fe, Cu, and Cr, D represents at least one element selected from Mg, Ca, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, Sc, and Y, 1≤x≤1.1, 0<y≤1, 0≤z<1, 0.9<y+z≤1) with a carbonaceous film, in which a saturated adsorbed moisture amount in a carbonaceous film single body, which is detected in a temperature range of room temperature or more and 250° C. or less by means of Karl Fischer (coulometric titration), is 5000 ppm or more and 50000 ppm or less.
