“…In addition to the above fact, it is interesting to observe that the displacement between Ni 3C ions at the octahedral 3b sites and Li C ions at the 3a sites in the space group R-3m weakens the intensity of the (003), while such a displacement did not affect the intensity of the (104) line [22]. Actually, increasing amount [23]. Generally, the non-stoichiometry of lithium nickelate (Li 1Kx Ni 1Cx O 2 ) results from the instability of trivalent Ni ions during the high temperature synthesis of the compound.…”

“…This may impede the motion of the lithium ions leading to the deterioration of the electrode during charge and discharge. In this regard, Yamada et al [69] measured the initial discharge capacity as a function of average oxidation state of Ni in LiNiO 2 materials. They observed that the initial discharge capacity was the highest when the oxidation state of nickel ion was 3.0, corresponding to the high crystal quality of LiNiO 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 .

“…Thus first-principle calculations really gave the evidence that the polarisation mechanism had to be taken into account to explain the sign of the real shift observed, rather than the correlation one. 38 On the basis of these recent NMR results, we synthesised Li 1 2 and also the influence of the departure from the ideal stoichiometry z on the 6 Li and 7 Li static and MAS NMR signals. A structural analysis from the refinement of the XRD pattern using the Rietveld method is presented in the first section of the results.…”

A series of Li1-zNi1+zO2 materials have been synthesised by the coprecipitation route. An X-ray diffraction study was carried out on these materials using the Rietveld method to determine the departure from the ideal stoichiometry z, which ranges from 0 to 0.138. The actual Li/Ni ratio was also checked by chemical analyses using inductively coupled plasma (ICP) for each sample. The stoichiometric sample (z approximately 0) was obtained using a 15% Li excess. (6/7)Li NMR results from LiNiO2 (z approximately 0) show that the asymmetric shape of the NMR signal is due to anisotropy. Calculations give evidence that the paramagnetic dipolar interaction from the electron spins carried by Ni is anisotropic but does not completely explain the experimental anisotropy. (6)Li MAS NMR (magic angle spinning NMR) experiments and temperature standardisation NMR measurements unambiguously assign the isotropic position at +726 ppm. The static-echo NMR spectra of the non-stoichiometric Li1-zNi1+zO2 phases also exhibit an asymmetric shape whose width increases with the departure from the ideal stoichiometry z. (6/7)Li static and MAS NMR show that the 2zNi(2+) ions thus formed modify the dipolar interaction within the materials and also affect the Fermi contact interaction, since a distribution of Li environments is observed using (6)Li NMR for non-stoichiometric samples.

“…Then reported by the Sauvage [213], who prepared in the tavorite type structure LiFePO 4 OH. Investing the large electronegativity of sulfur and fluorine of LiMSO 4 F in produce high-voltage cathode materials such as LiFeSO 4 F transfer around 140 mAh/g with a high redox potential of 3.6 V [241][242][243][244]. Different Li metal fluorosulfate compounds (M=Mg, Mn, Fe, Co, Ni, Zn, Cu) were studied and shown a great electrochemistry and crystal chemistry counting on the type of metal ions and on the synthesis methods [227].…”

The development of cutting-edge cathode materials is a challenging research topic aiming to improve the energy and power densities of lithium ion batteries (LIB) to cover the increasing demands for energy storage devices. Therefore, highly needed further improvements in the performance characteristics of Li-ion batteries are largely dependent on our ability to develop novel materials with greatly improved Li ion storage capacities. Three different types of cathode materials including intercalation, alloying and conversion materials are reviewed in this paper in order to orientate our researches towards highly performant LIBs batteries. This includes characteristics of different cathode materials and approaches for improving their performances.
