Abstract
Official abstract text for this publication.
A titanium oxide compound according to the present invention comprises bronze-type titanium oxide or titanium oxide mainly composed of bronze-type titanium oxide, and contains calcium and/or silicon. The titanium oxide compound contains 0.005 to 2.5 mass % inclusive of calcium or 0.15 to 0.55 mass % inclusive of silicon, or contains 0.005 to 1.2 mass % inclusive of calcium and 0.15 to 0.2 mass % inclusive of silicon, or contains 0.005 to 0.1 mass % inclusive of calcium and 0.15 to 0.5 mass % inclusive of silicon.
First claim
Opening claim text (preview).
The invention claimed is: 1. A titanium oxide compound comprising bronze-type titanium oxide or titanium oxide mainly composed of bronze-type titanium oxide, wherein the titanium oxide contains 0.005 to 2.5 mass % inclusive of calcium, an average aspect ratio of primary particles of the titanium oxide compound is in a range from 3.28 to 5.74, and the titanium oxide is in a form of plate-shaped crystals. 2. The titanium oxide compound according to claim 1 , wherein at least a part of the calcium exists as a solid solution in titanium oxide crystals. 3. The titanium oxide compound according to claim 1 , wherein pore volume of the titanium oxide compound is 0.01 to 0.5 mL/g, and specific surface area thereof is 1.0 to 20 m 2 /g. 4. An electrode, wherein at least part of an electrode active material of the electrode is the titanium oxide compound according to claim 1 . 5. A lithium ion secondary battery using the electrode according to claim 4 as positive electrode or negative electrode.
