“…The characterization of the deposited Ni-Al LDH was carried out by XRD, FE-SEM, SEM-EDX, and ICP-AES. The composition formulas of the Ni-Al LDH on nickel foam, LDH/Ni foam, the Ni-Al LDH on carbon black powder, LDH/CB, and the powdered Ni-Al LDH which were determined from the ICP-AES measurement were Ni 0.77 Al 0.23 (OH) 2 2 ·X 0.24 , respectively (X means the ion exchangeable univalent anions between the LDH layers). The existence of aluminum fluoride complexes could not be confirmed at all by Raman and IR measurements as well as our previous report.…”

The direct synthesis of an Ni-Al layered double hydroxide (LDH) as the active material in an Ni-metal hydride secondary battery on an electron-conductive substrate was performed using liquid phase deposition method. A reduction in charge-transfer resistance was achieved by coating a Ni-Al LDH film on a Ni foam surface current collector, as a result of improved adhesion between the current collector and the active material.

“…For the activation treatment, the resultant Zr 0.6−x Ti 0.4 Nb x Ni negative electrodes were soaked in a boiling 6 M KOH alkaline solution for 4 h [8,9]. The positive and reference electrodes were NiOOH/Ni(OH) 2 and Hg/HgO electrodes, respectively. The electrolyte solution (100 mL) was a 6 M KOH aqueous solution containing 1 M LiOH.…”

“…The normalized discharge capacity (NDC) at 333 and 303 K for the Zr0.6−xTi0.4NbxNi (x = 0, 0.01, 0.02, and 0.05) negative electrodes was plotted as a function of cycle number in Figure 5c,d, respectively. The NDC is defined by the following equation [24]: NDC (%) = 100Cdis,n/Cdis,max (2) where Cdis,n is the discharge capacity at the n-th cycle, and Cdis,max is the maximum discharge capacity. At 333 K, the NDC values at the 10th cycle for the alloy negative electrodes with x = 0, 0.01, 0.02, and 0.05 were 74%, 77%, 83%, and 87%, respectively.…”

Abstract:Crystal structure, pressure-composition isotherms and electrochemical properties of the Zr 0.6−x Ti 0.4 Nb x Ni (x = 0.01, 0.02, and 0.05) alloys were investigated. Their X-ray diffraction profiles demonstrated that all the Zr 0.6−x Ti 0.4 Nb x Ni alloys consisted of the primary phase with the B33-type orthorhombic structure and the secondary phase with the B2-type Ti 0.6 Zr 0.4 Ni cubic structure. Rietveld refinement demonstrated that the atomic fraction of the secondary phase increased with the Nb content. The Zr 0.6−x Ti 0.4 Nb x Ni alloys were lower in hydrogen storage capacity than the Nb-free Zr 0.6 Ti 0.4 Ni alloy due to an increase in the abundance of the secondary phase. In the charge-discharge tests with the Zr 0.6−x Ti 0.4 Nb x Ni alloy negative electrodes, all the initial discharge curves had two potential plateaus due to the electrochemical hydrogen desorption of trihydride to monohydride and monohydride to alloy of the primary phase. The total discharge capacities at 333 and 303 K for the Zr 0.58 Ti 0.4 Nb 0.02 Ni alloy negative electrode were 384 and 335 mAh g −1 , respectively, which were higher than those of the other Zr 0.6−x Ti 0.4 Nb x Ni and Zr 0.6 Ti 0.4 Ni alloy negative electrodes.

Ni‐MH battery is developed and commercialized with lithium‐ion battery almost at the same time, to replace the environmentally unfriendly Ni/Cd battery and meet the increasing energy density requirements of consumer electronic devices. The success of Ni‐MH battery in consumer and industrial markets is mainly attributed to its specific negative electrode materials, namely a large variety of intermetallic compounds with reversible hydrogen absorption and desorption during charging and discharging. A unique hydrogen shuttle mechanism through the aqueous alkaline electrolyte between the layered Ni(OH) 2 cathode and interstitial metal hydride anode could be thus achieved. Hydrogen as the charge carrier in Ni‐MH battery is like the lithium ion in the lithium‐ion battery. The simple and robust structure of Ni‐MH battery brings high safety under various conditions, making Ni‐MH battery very competitive in applications demanding safety priority, such as hybrid electric vehicles. The brief history, basic structure, research, and development of electrode materials of Ni‐MH battery are introduced, with the emphasis on the hydrogen storage electrode alloys. Future development of Ni‐MH battery is expected to be focused on the automotive and stationary energy storage applications by greater innovation in the hydrogen storage alloy anodes with ultra‐high capacity and overall electrochemical properties.
