A new class of nanocomposites of Zn–Al–Bi layered double oxides: large reversible capacity and better cycle performance for alkaline secondary batteries

Abstract

Zn–Al–Bi layered double oxide (Zn–Al–Bi-LDO) nanocomposites with a bilayer structure were prepared by calcining Zn–Al–Bi layered double hydroxides (Zn–Al–Bi LDHs) in an air atmosphere at 600 °C for 6 h.
