Abstract

The present invention provides a layered double hydroxide with improved conductivity, a layered double hydroxide and a composite material containing the layered double hydroxide. The layered double hydroxide is represented by the general formula: [MgM1][AlM2](OH)A.mHO, wherein 0.1≤x≤0.4, 0≤y≤0.95, and 0≤z≤0.95, provided that both y and z are not 0 at the same time; α=1 or 2; β=2 or 3; Ais an n-valent anion, provided that n is an integer of 1 or greater; m≥0; M1is a cation of at least one substituent element selected from monovalent elements, transition metal elements, and other elements with an ionic radius greater than that of Mg; and M2is a cation of at least one element selected from divalent elements, transition metals, and other elements with an ionic radius greater than that of Al.
