Patent number: 9350018
Abstract: A secondary battery includes: a fiber negative electrode having a surface on which a negative electrode active material coating is formed, the coating containing a compound of AaMbXcZd; a fiber positive electrode including a positive electrode active material coating containing nickel hydroxide; an aqueous electrolyte solution; and a separator. The negative electrode coating has an uncoated surface. A is selected from the group consisting of Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, and Ba; M is selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Nb, Mo, Ru, Pd, Ag, Ta, W, Pr, Sm, Eu, and Pb; X is selected from the group consisting of B, Al, Si, P, S, Ga, and Ge; Z is selected from the group consisting of O, S, N, F, Cl, Br, and I; and 0?a?6, 1?b?5, 0?c?4, 0<d?12, and 0?a/b?4.
