First claim
Opening claim text (preview).
The invention claimed is: 1. A negative-electrode active material for a power storage device, the negative-electrode active material containing, in terms of % by mole of oxide, 1 to 95% TiO 2 and 5 to 75% P 2 O 5 +SiO 2 +B 2 O 3 +Al 2 O 3 +R′O (where R′ represents at least one selected from Mg, Ca, Sr, Ba, and Zn), 12.5% or less Li 2 O, and containing 10% by mass or more amorphous phase. 2. The negative-electrode active material for a power storage device according to claim 1 , further containing 1 to 70% R 2 O (where R represents at least one selected from Li, Na, and K). 3. The negative-electrode active material for a power storage device according to claim 1 , wherein the negative-electrode active material is made of an amorphous phase. 4. The negative-electrode active material for a power storage device according to claim 1 , wherein the negative-electrode active material is for use in a sodium-ion secondary battery. 5. A negative electrode material for a power storage device containing the negative-electrode active material for a power storage device according to claim 1 . 6. The negative-electrode active material for a power storage device according to claim 1 , further containing 1 to 70% Na 2 O.
