Abstract
Provided is a battery including a layered double hydroxide. The battery includes a positive electrode, a negative electrode, an electrolytic solution being an aqueous alkali metal hydroxide solution, and a layered double hydroxide having a fundamental composition represented by the formula: MM(OH)A·mHO where Mrepresents a divalent cation, Mrepresents a trivalent cation, Arepresents an n-valent anion, n is an integer of 1 or more, x is 0.1 to 0.4, and m is any real number, the layered double hydroxide being in contact with the electrolytic solution, wherein a metal compound containing a metal corresponding to Mand/or Mis dissolved in the electrolytic solution such that erosion of the layered double hydroxide by the electrolytic solution is suppressed. The present invention provides a highly reliable battery such that the degradation of a layered double hydroxide (LDH) contained in the battery can be significantly reduced.
