“…However, the existence of incomplete reversible phase transformation and local structural damage result in poor rate capability and serious capacity loss during the insertion of lithium [59,60]. Herein, Huang et al [61] reported that the performance of layered LiV3O8 cathode material could be enhanced when surface modified with Al2O3. They have synthesized surface modified-LiV3O8 materials by a simple thermolysis method.…”

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.

“…Among all the vanadium-based cathode materials, LiV 3 O 8 can be the most extensively studied category and has been regarded as the best potential candidate for cathode materials of LIBs [236][237][238][239][240][241][242][243]. The layered monoclinic LiV 3 O 8 consists of two basic structural units of VO 6 octahedra and VO 5 trigonal bipyramids, which form two different sites for Li + : Octahedral and tetrahedral.…”

Lithium ion batteries (LIBs) represent one of the most promising solutions for environmentally friendly transportation such as electric vehicles. The demand for high energy density, low cost and environmentally friendly batteries makes high-capacity cathode materials very attractive for future LIBs. Layered LiNi x Co y Mn z O 2 (x+y+z=1), Li-rich oxides and Li-V-O compounds have attracted much attention due to their high capacities in recent years. In this review, we focus on the state-of-the-art research activities related to LiNi x Co y Mn z O 2 , Li-rich oxides and Li-V-O compounds, including their structures, reaction mechanisms during cycling, challenges and strategies that have been studied to improve their electrochemical performances. layered LiNi x Co y Mn z O 2 , Li-rich layered oxide, Li-V-O compound, cathode material, Li-ion battery Citation: Zhang Y D, Li Y, Xia X H, et al.

“…It is interesting to note that a three layered Al 2 O 3 /Li x V 2 O 5 /LiV 3 O 8 nanostructure was well formed, which is much different from that in ref. [25]. When used as a cathode for Li-ion battery, the composite electrode exhibits significantly improved cycling stability with a discharge capacity of 203 mAh g À1 remaining after 200 cycles at 150 mA g À1 .…”

“…A number of efforts have been devoted to LiV 3 O 8 [5,[19][20][21][22][23][24][25][26]. Idris et al [19] reported carboncoated LiV 3 O 8 , which could be cycled up to 250 cycles without considerable capacity loss at 20C.…”

“…Al 2 O 3 modified LiV 3 O 8 was once reported in ref. [25] via a thermolysis process and the improved electrochemical properties were mainly attributed to the joint action of Al 2 O 3 coating and Li-V-Al-O solid solution at the LiV 3 O 8 /Al 2 O 3 interface which could provide a fast Li-ion diffusion path. However, it should be noted that the capacity retention ratio of Al 2 O 3 /LiV 3 O 8 after 100 cycles at 2000 mA g À1 was just 71.3%, which was far insufficient.…”
