Titanic Acid Compound, Process For Producing The Titanic Acid Compound, Electrode Active Material Containing The Titanic Acid Compound, And Storage Device Using The Electrode Active Material |
摘要 |
This invention provides a titanic acid compound-type electrode active material having a high battery capacity and, at the same time, having excellent cycle characteristics. The titanic acid compound exhibits an X-ray diffraction pattern corresponding to a bronze-type titanium dioxide except for a peak for a (003) face and a (−601) face and having a lattice spacing difference between the (003) face and the (−601) face, i.e., d(003)−d(−601), of not more than 0.0040 nm. The titanic acid compound may be produced by reacting a layered alkali metal titanate, represented by a compositional formula MxM′x/3Ti2-x/3O4 wherein M and M′, which may be the same or different, represent an alkali metal; and x is in the range of 0.50 to 1.0, with an acidic compound and then heating the reaction product at a temperature in the range of 250 to 450° C.
