Document Type and Number:
Japanese Patent JP6652534
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrode capable of obtaining excellent life characteristics.SOLUTION: According to an embodiment, there is provided an electrode 3. The electrode 3 includes an active material-containing layer 3b. The active material-containing layer 3b includes a Na-containing niobium titanium composite oxide having a monoclinic crystal structure. The active material-containing layer 3b satisfies I/I≥1 where Irepresents the intensity of a peak Pappearing in a binding energy range of 289-292 eV in an X-ray photoelectron spectroscopy spectrum obtained by X-ray photoelectron spectroscopy on the active material-containing layer 3b, and Irepresents the intensity of a peak Pappearing in a binding energy range of 283-285 eV in an X-ray photoelectron spectroscopy spectrum of the active material-containing layer 3b.SELECTED DRAWING: Figure 1
