Electrical storage device including fiber electrode, and method of fabricating the same
An object of the present invention is to provide a highly efficient electrical storage device that uses a fiber positive electrode and a fiber negative electrode and in which lithium ion is used as an intercalating species, and to provide a method of fabricating the electrical storage device. The electrical storage device according to the present invention includes: a fiber positive electrode including an electrically conductive fiber, the fiber having a surface on which a positive electrode active material coating is formed, the positive electrode active material coating containing a transition metal oxide represented by a chemical formula 1 which is (Li1-xAx)aMbXcOd; a fiber negative electrode including an electrically conductive fiber, the fiber having a surface on which a negative electrode active material coating is formed; a separator; and an electrolyte (in the chemical formula 1, A is at least one kind of alkali metal selected from the group consisting of Na, K, Rb, and Cs; M is at least one kind of transition metal selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Nb, Mo, Ru, Pd, Ag, Ta, W, Ce, Pr, Sm, Eu, and Pb; X is at least one kind of typical elements selected from the group consisting of B, Al, Si, P, S, Ga, and Ge; and 0<a≦6, 1≦b≦5, 0≦c≦4, 0<d≦12, 0≦a/b≦4, and 0≦x≦0.5).
