“…1. Most of the peak positions for the flame spray pyrolyzed V2O5 nanoparticles agree well with those of the orthorhombic V2O5 (JCPDS 41-1426; a = 11.5160 Å, b = 3.5656 Å, and c = 4.3727 Å), except for the 2 peaks marked as "@" and "#" which correspond to the (110) and (011) peaks from the monoclinic VO2 (JCPDS 43-1051) impurities present, as observed also by Schimmoeller et al 37 Moreover, based on the fundamental parameter approach and the Rietveld method, 39 DXRD ranging from 20 to 28 nm was estimated from peak (001) of the V2O5 phase (see Fig. 1a-f, also listed in Table 1).…”

Vanadium pentoxide (V2O5) nanoparticles (30-60 nm) were made by a one-step and scalable flame spray pyrolysis (FSP) process. Optimization of the FSP processing conditions (precursor concentration and injection rate) enhanced the electrochemical performance of these nanoparticles. Increasing the cut-off potential for discharging from 1.5 to 2.5 V vs. Li/Li + improved the cycle life of these V2O5 nanoparticles. Particles with the lowest specific surface area ( 32 m 2 g −1 ) and highest phase purity (up to 98 wt%) showed excellent cyclability between 2.5 and 4.0 V vs. Li/Li + , retaining a specific charge of 110 mAh g −1 beyond 100 cycles at a specific current of 100 mA g −1 , and also superior specific charge of 100 mAh g −1 at specific current up to 20C rate (or 2000 mA g −1 ).

“…The Li from LiNiO 2 cannot be fully re-inserted during the subsequent reduction step due to the structural transformation to Li 1Kx NiO 2 . After a few cycles, the reversible reaction can be described as follows: The practical specific discharge capacity of LiNiO 2 is about 125-150 mAh/g [67]. Contrary to these observations, in the case of LiCoO 2 , the lithium after the first charging process is completely re-inserted during the following discharge process [41].…”

“…In general, the Li C intercalation/deintercalation mechanism may be understood from cyclic voltammetric studies [67]. It is interesting to note that the mechanism of Li intercalation/deintercalation is quite different for LiNiO 2 and LiCoO 2 .…”

Despite the appearance of ever first report on the synthesis of LiNiO 2 in 1954, active research to identify and evaluate its suitability as an electrode material in rechargeable lithium batteries started only in late 80's. Following this, numerous articles discussed the synthesis, electrochemical behavior and the problems associated with the compound. In this connection, the present communication reviews certain important experimental results obtained by different research groups on various aspects of LiNiO 2 , in order to understand the significance of LiNiO 2 as a potential cathode material for rechargeable lithium batteries. Also selected type of methodologies adopted to synthesize the title compound have also been discussed to substantiate the dependence of electrochemical behavior of LiNiO 2 on the method of synthesis and reaction conditions. The subject has been discussed at length and may provide useful information on the properties of LiNiO 2 and may enable the fabrication of tailor made nickel-based electrode materials for 'next generation' lithium or lithium-ion batteries along with the highlights of doped and coated derivatives of LiNiO 2 .

“…Research in cathode materials for rechargeable lithium batteries has a great deal of interest on the layered LiNiO 2 and LiCoO 2 materials in recent years [4][5][6]. Doped LiNiO 2 may possess better electrochemical properties than LiNiO 2 or LiCoO 2 .…”

Lithium nickel cobalt oxide materials doped with Al, Mg, and Fe were synthesized by solid-state reaction at 800°C for 18 h to study the effects of adding transition and nontransition metals to the structure. Crystalline compounds were obtained as revealed by powder X-ray diffraction (XRD). Energy dispersive analysis of X-rays (EDAX) was used to determine the elemental ratio of all the samples. Impedance measurements showed that all samples have decreasing conductivities at higher temperatures and gave negative activation energies. The addition of nontransition metals actually decreased the conductivities of the materials.
