The use of layered double hydroxides (LDH) of Ni with Cr and Mn as electrode materials for alkaline secondary cells was studied. The presence of Cr and Mn suppresses β-nickel hydroxide formation which indicates their strong influence on the precipitation behavior of Ni2+. It is found that the LDH of Ni with Cr and Mn are electrochemically active and deliver capacities of 500 (Ni-Cr), 400 (Ni-Mn, x = 0.2) and 430 (Ni-Mn, x = 0.1) mAhg-1 of Ni respectively
