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.

“…a-and b-form. b-Co(OH) 2 is a stoichiometric phase of the composition Co(OH) 2 with a brucite-like structure (a = 3.12 Å, c = 4.6 Å) [13,14], while a-form Co(OH) 2 has a similar structure to layered double hydroxides (LDHs) that are composed of hydrotalcite-like layers with a positive residual charge and a series of hydrated anions in the interlayer space to keep charge balance, resulting in a substantial expansion on the interlayer spacing (>7 Å) [15][16][17]. The intercalated anions between the hydrotalcite-like host layers of a-Co(OH) 2 are exchangeable, leading to a possibility for adjusting the interlayer spacing [15,18].…”

“…Layered double hydroxides (LDHs), also called hydrotalcite‐like compounds or anionic clays, consist of positively charged metal hydroxide sheets, interlayer anions and water. They can be represented by a general formula,

{[{normalM}_{1 - x}^{2 +} {normalM}_{x}^{3 +} ({OH}_{2})]}^{x +} {normalA}_{x / n}^{n -} {\cdot yH}_{2} O

, where M 2+ and M 3+ stand for divalent and trivalent metal cations respectively, and A n ‐ is the interlayer anions; y is the amount of interlayer H 2 O. Owing to their adjustable composition and structure, LDHs have many unique chemical properties and are used as fire‐retardants , catalysts , adsorbents , electrochemical materials , and others .…”

This article demonstrates a green route for synthesis of Ca‐doped [Mg3Al(OH)8]Cl from a reaction of AlCl3·6H2O, Mg(OH)2, Ca(OH)2, and NH3·H2O in water, which produces only the desired solid product and a by‐product NH4Cl in the mother solution; therefore, they can be separated easily by filtration or centrifugation. Being carefully designed, enough NH4Cl can be crystallized from the mother solution, which could be used as a fertilizer; while the distilled water be used to wash the products for the last time; the mother solution that still contains some NH4Cl and filtrate from the first time washing of the product can be used to prepare the LDH again. By using cheaper Mg(OH)2 and Ca(OH)2 instead of MgCl2·6H2O and CaCl2·2H2O, the process is more economic and produces less NH4Cl. © 2014 American Institute of Chemical Engineers Environ Prog, 34: 234–239, 2015
