“…Meanwhile, the product LiV 3 O 8 has a low capacity, such as 180 mAh/g in the range of 2.0-3.7 V [6]. Afterwards, many improved solution methods were proposed [7][8][9][10]. These solution methods do not need high reaction temperature, and the products could reach higher homogeneity and capacity.…”

“…Among several known vanadium oxides, metastable oxides designated as VO 2 (B), V 6 O 13 , V 2 O 5 and V 3 O 8 are the most interesting cathodes for lithium ion batteries. [55][56][57][58] Among these vanadium derivatives, the layered vanadium pentoxide, LiV 2 O 5 has been the most studied in spite of its low discharge voltage, low electric conductivity and slow diffusion kinetics of lithium ion. 59,60 To improve the performance of cells employing vanadium pentoxide as cathode several tricks have been tested, including the use of aerogels, 61-63 xerogels, [64][65][66] nanocomposites of LiV 2 O 5 with electronically conducting organic polymers 17,60,[67][68][69][70][71][72][73][74][75][76][77][78] and nanostructured materials (nanotubes, nanorods and nanoparticles).…”

“…Notably, the value of 300 mA h g -1 is considerably higher than the capacities of 220-270 mA h g -1 obtained for LiV 3 O 8 prepared by other methods. 58,90,96,97 TEM micrographies and XRD data have showed that heat treatment performed at high temperatures cause changes in the LiV 3 O 8 crystallinity and morphology and larger and more crystalline particles are obtained at 600 o C. Both the small size and the disordered structure are responsible for this appreciable electrochemical response.VO 2 (B) has been emerged as another good option as cathode material for lithium ion batteries since 1996. 98 Its structure is built up by distorted octahedral VO 6 that shares both corners and edges, where lithium ions can occupy both octahedral and tetrahedral sites.…”

As celas de íon lítio disponíveis comercialmente, as quais são as mais avançadas entre as baterias recarregáveis disponíveis até agora, empregam óxidos de metais de transição microcristalinos como catodos, os quais funcionam como matrizes de inserção de lítio. Em busca por uma melhor performance eletroquímica, o uso de nanomateriais no lugar dos materiais convencionais tem emergido como excelente alternativa. Nesta revisão nós apresentaremos uma breve introdução sobre as motivações de usar materiais nanoestruturados como catodos em baterias de íon-lítio. Para ilustrar tais vantagens apresentamos exemplos de pesquisas relacionadas com a preparação e dados eletroquímicos dos mais usados catodos em nanoescala, tais como LiCoO 2 , LiMn 2 O 4 , LiMnO 2 , LiV 2 O 5 e LiFePO 4 .Commercially available lithium ion cells, which are the most advanced among rechargeable batteries available so far, employ microcrystalline transition metal oxides as cathodes, which function as Li insertion hosts. In search for better electrochemical performance the use of nanomaterials in place of these conventional ones has emerged as excellent alternative. In this review we present a brief introduction about the motivations to use nanostructured materials as cathodes in lithium ion batteries. To illustrate such advantages we present some examples of research directed toward preparations and electrochemical data of the most used cathodes in nanoscale, such as LiCoO 2 , LiMn 2 O 4 , LiMnO 2 , LiV 2 O 5 e LiFePO 4 .Keywords: nanotechnology, lithium-ion battery, cathode, nanoparticles Initial RemarksSince Sony introduced its 18650 cell in 1990, 1 Li-ion batteries with excellent electrochemical performance have been manufactured and occupied a prime position in the market place 2 to power portable and non-portable devices. [3][4][5] The reason for this relevance is that compared to traditional rechargeable batteries such as, lead acid and Ni-Cd, the lithium-ion battery shows several advantages, such as lighter in weight, smaller in dimension and higher energy density. 1 Moreover, although capacity values may be similar to other rechargeable systems, voltages are approximately three times higher, affording higher energy. 1 In general, the commercial lithium-ion batteries use graphite-lithium composite, Li x C 6 , as anode, lithium cobalt oxide, LiCoO 2 , as cathode and a lithium-ion conducting electrolyte. When the cell is charged, lithium is extracted from the cathode and inserted at the anode. On discharge, the lithium ions are released by the anode and taken up again by the cathode (Figure 1).Owing to the importance of lithium ion batteries, these cells are still object of intense research to enhance their properties and characteristics. The searches focus on all aspects of these batteries, including improved anodes, 6-8 cathodes 9-17 and electrolytes. [18][19][20][21][22] However, most of these efforts are concentrated in new cathode materials, since the most used cathode material (LiCoO 2 ) is expensive and is somewhat toxic.The active catho...

A series of cathode materials for lithium ion batteries with the formula LiV3O8−xClx (x=0.00, 0.05, 0.10 and 0.15) were synthesized by a low‐temperature solid‐state method. The effects of Cl− substitution on the structure, morphology and electrochemical properties of the cathode materials were investigated through X‐ray diffraction (XRD), scanning electron microscopy (SEM), charge‐discharge test, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) experiments. The results show that an enhanced cycle performance is on the Cl− doped cathode materials. LiV3O7.90Cl0.10 shows the best electrochemical performances with the discharge capacity remaining 198.6 mAh/g after 100 cycles, which results from a greater reversibility during cycling and decrease of particle‐to‐particle impedance.
