Effects of the composition on the properties of nickel-aluminum layered double hydroxide/carbon (Ni-Al LDH/C) composite fabricated by liquid phase deposition (LPD)

► We report the optimized preparation of Ni-Al LDH/C composite by the LPD method. ► We investigate the influence of the LDH content on the properties of the composite. ► The crystallinity of the composite increases with increasing the LDH content. ► The optimized composition results in high performance cathode materials. ► The electrode displays high discharge capacity, good cycle life and excellent electrochemical stability.
