Electrochemical investigation of the Li insertion–extraction reaction as a function of lithium deficiency in Li1−xNi1+xO2

Magnetic analysis of lamellar oxides for Li-ions batteries

“…Actually, if the value of θ were dictated by the defects, we would have the linear law θ∝z. Some authors have even proposed to use this law to determine z [15]. However, it does not hold true.…”

Synthesis of LiNiO2 thin film in LiOH solution by hydrothermal method

“…LiNiO 2 is considered as one of the promising cathode materials for lithium batteries due to its low cost, high energy density and non-toxicity. However, it is difficult to synthesize LiNiO 2 with controlled composition and microstructure because of its tendency for non-stoichiometry, resulting in Li 1−x Ni 1+x O 2 rather than stoichiometric LiNiO 2 [9,10]. As the miniaturization of electronic devices progresses, the need to develop suitable micro-battery systems as power sources for the microelectronic devices increases, so the fabrication of the lithiated intercalation cathode films (including LiCoO 2 , LiNiO 2 and LiMn 2 O 4 films) has been intensively investigated lately [5,[11][12][13][14][15][16].…”

Chemistry and electrochemistry of nanostructured iron oxyhydroxides as lithium intercalation compounds for energy storage

“…The most studied cathodic compounds are layered materials like LiCoO 2 (almost the only one to be currently marketed) [4][5][6][7][8] and LiNiO 2 [9][10][11][12]. The use of this last one, which has however a capacity higher than LiCoO 2 , was always delayed because of instability problems at the charged state due to a strong exothermic reaction with organic electrolytes [13,14].…”
