“…It is worth noting that these hurdles can be possibly overcome with structural and compositional modifications. Recently, Ni‐Al LDH/carbon composites have been fabricated by liquid‐phase deposition and showed a high capacity at a discharge rate of 2 C, making them potential cathode materials 126…”

There is an ever-growing demand for rechargeable batteries with reversible and efficient electrochemical energy storage and conversion. Rechargeable batteries cover applications in many fields, which include portable electronic consumer devices, electric vehicles, and large-scale electricity storage in smart or intelligent grids. The performance of rechargeable batteries depends essentially on the thermodynamics and kinetics of the electrochemical reactions involved in the components (i.e., the anode, cathode, electrolyte, and separator) of the cells. During the past decade, extensive efforts have been dedicated to developing advanced batteries with large capacity, high energy and power density, high safety, long cycle life, fast response, and low cost. Here, recent progress in functional materials applied in the currently prevailing rechargeable lithium-ion, nickel-metal hydride, lead acid, vanadium redox flow, and sodium-sulfur batteries is reviewed. The focus is on research activities toward the ionic, atomic, or molecular diffusion and transport; electron transfer; surface/interface structure optimization; the regulation of the electrochemical reactions; and the key materials and devices for rechargeable batteries.

The effect of nickel content on the structure and activity of co-precipitated Ni-Al layered double hydroxides (LDHs) as catalyst precursors for CO 2 removal by methanation was studied by variation of the Ni 2? /Al 3? molar ratio (Ni 2? /Al 3? = 3.0, 1.5 and 0.5), and of the reduction and reaction temperatures as well as of the space velocities. Powder X-ray diffraction (PXRD), H 2 chemisorption, and temperature programmed reduction (TPR) techniques were applied for physicochemical characterization of the samples. It was specified that the nanoscaled dimensions of the as-synthesized samples also generate nano-metrical metallic nickel particles (PXRD). The existence of readily and hardly reducible Ni 2? -O species in the studied samples (TPR), affects catalytic performance. The studied catalysts hydrogenate CO 2 effectively to residual concentrations of the latter in the range of 0-10 ppm at reaction temperatures from 400 to 220°C and space velocities between 22,000 and 3000 h -1 . The variation of the CO 2 methanation activity with the changes of space velocities depends on the nickel content, and reduction and reaction temperatures. After reduction at 400 and 450°C, a sample of Ni 2? /Al 3? = 3.0 has demonstrated the highest conversion degree at all the reaction temperatures and space velocities, while a catalyst of Ni 2? /Al 3? = 0.5 dominated in the methanation activity after reduction within 530-600°C. The Ni 2? /Al 3? = 1.5

“…Nickel-aluminum layered double hydroxide/carbon (Ni-Al LDH/C) Béléké et al [249][250][251][252] demonstrated a novel synthetic method to prepare Ni-Al LDH/C for the applications in battery systems, which was called liquid phase deposition (LPD) [253][254][255][256][257]. Unlike traditional LPD process, this approach used Al(NO3)3 as a raw material directly to receive Ni-Al LDH and a fluoride scavenger.…”

There has been increasing interest in developing micro/nanostructured aluminum-based materials for sustainable, dependable and high-efficiency electrochemical energy storage. This review chiefly discusses the aluminum-based electrode materials mainly including Al2O3, AlF3, AlPO4, Al(OH)3, as well as the composites (carbons, silicons, metals and transition metal oxides) for lithium-ion batteries, the development of aluminum-ion batteries, and nickel-metal hydride alkaline secondary batteries, which summarizes the methodologies, related charge-storage mechanisms, the relationship between nanostructures and electrochemical properties found in recent years, latest research achievements and their potential applications. In addition, we raise the relevant challenges in recently developed electrode materials and put forward new ideas for further development of micro/nanostructured aluminum-based materials in advanced battery systems.
