“…The formation of pure LiNiO 2 is thus difficult, and residual Ni(II) (up to 1-2%) exists between the NiO 2 slabs. Essentially, the first cycle irreversibility during charge-discharge is related to the amount of Ni(II) between the slabs of NiO 2 , which require extra charge for oxidation to higher valence state, when electrolyte decomposition is controlled [63].…”

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 .

“…Galvanostatic discharge studies were carried out at a current rate of 0.1 C. Figure 1 shows X-ray powder diffraction (XRD) patterns of LiCo 1-x Sn x O 2 (x = 0, 0.01, 0.03, 0.05 and 0.1) samples annealed at 800 ºC for 12 h. All the samples have the peaks for the phase with the a-NaFeO 2 structure of the rhombohedral system (space group; R-3m). The patterns also show clear split of the (006)/(102) and (108)/(110) peaks, indicating all the compounds except heavily doped (x=0.1) sample have a high degree of ordered hexagonal structure [17,18]. The hexagonal unit cell parameters calculated for all the products were shown in table 1.…”

Layered intercalation compounds LiCo 1-x Sn x O 2 (x= 0 to 0.1) have been prepared using a simple combustion route method. X-ray diffraction patterns and Laser Raman spectrum suggest that the synthesized materials had the R-3m structure. Scanning electron images show that particles are well-crystallized with a size distribution in the range of 50-100 nm. The room temperature electrical conductivity of the sample increased with Sn content. For LiCo 1-x Sn x O 2 (x = 0, 0.01, 0.03, 0.05 and 0.1), the first discharge capacity increased with increase in Sn content. Among these samples, LiCo 0.95 Sn 0.05 O 2 had produced the best performance of all others with a stable reversible capacity of 186 mAhg -1 after 30 cycles.

“…When the inclusion of half mole of titanium, the peak becomes slightly broaden and the intensity of peak is decreased, which indicates the crystallization is weakened for the titanium-doped materials [11]. The two characters of X-RD patterns, i.e., I 003 /I 004 ratio and 108/110 or 006/012 peak splitting, were the main criteria for the degree of ordering in layered structure as well as the amount of transition metal in the inter slab space [19,20]. The structure of LiCoTi 0.50 O 2 is basically identical, and this indicates that the introduction of titanium into a LiCoO 2 does not affect the local structure of Co.…”

The lithiated transition metal oxide has been used as the cathode materials for lithium ion rechargeable batteries. Among the various cathode materials, LiCoO 2 has been widely used. There are lot of reports on the substituted LiCoO 2 replacing small amount of Cobalt with other transition and nontransitional metals. Here, we focus on to a tetravalent transition metal atom such as titanium, as an addition in LiCoO 2 and studied its performance. The titled cathode material was synthesized by solid-state reaction method. Thermogravimetric/differential thermal analysis, X-ray diffraction, X-ray fluorescence, scanning electron microscopy, and particle size analysis were carried out to assess the effect of addition of titanium on LiCoO 2 . Electrochemical studies were carried out by cyclic voltammetry and life cycle analyzer.
