Abstract
A layered double hydroxide is represented by the following formula (I): Ni2+1−(x+y+z)Fe3+xV3+yCo3+z(OH)2An−(x+y+z)/n·mH2O . . . (I). In one embodiment, in the formula (I), (x+y+z) is from 0.2 to 0.5, “x” represents more than 0 and 0.3 or less, “y” represents from 0.04 to 0.49, and “z” represents more than 0 and 0.2 or less.
