Title:
NEGATIVE ELECTRODE FOR SECONDARY BATTERY AND SECONDARY BATTERY PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2012/042696
Kind Code:
A1
Abstract:
This secondary battery is provided with a fiber negative electrode on which a negative electrode active material coating containing a compound represented by chemical formula (1), AaMbXcZd, is formed on the surface of carbon fiber. This secondary battery is also provided with a fiber positive electrode on which a positive electrode active material coating containing nickel hydroxide is formed on carbon fiber, an aqueous electrolyte, and a separator. The surface of the negative electrode active material coating is covered by a conductive substance. In chemical formula (1), A is at least one metal element selected from a group formed from Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, and Ba; M is at least one transition metal element selected from a group formed from Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Nb, Mo, Ru, Pd, Ag, Ta, W, Pr, Sm, Eu, and Pb; X is at least one representative element selected from a group formed from B, Al, Si, P, S, Ga, and Ge; Z is at least one representative element selected from a group formed from O, S, N, F, Cl, Br, and I; 0 ≤ a ≤ 6; 1 ≤ b ≤ 5; 0 ≤ c ≤ 4; 0 < d ≤ 12; and 0 ≤ a/b ≤ 4.
