Synthesis and Properties of Nanoparticle Li[Li0.2Mn0.54Ni0.13CO0.13]O2Cathode Material by Coprecipitation Method with Non-aqueous Medium

“…The hexagonal lattice parameter of the prepared Li[Li 0.2 Mn 0.54 Ni 0.13 Co 0.13 ]O 2 were determined to be a=0.2851nm and c=1.4233nm. These data match well with the values observed by other reports [16,17]. The value of c/a=4.992 reveals that the well defined hexagonal structure is formed.…”

“…Cation mixing is known to deteriorate the electrochemical performance of the above layered compound. The integrated intensity ratio of I003/I104 (R) is sensitive to the cation mixing [11,12]. Researchers often used high intensity ratio of I003/I104 (R) to indicate the cation mixing of the layered structure [13].…”

Effects of Sn doping on electrochemical characterizations of Li[Ni1/3Co1/3Mn1/3]O2 cathode material

“…Therefore, many researchers have been extensively studying alternatives to LiCoO 2 . Among all of the candidates, Li[Ni 1/3 Co 1/3 Mn 1/3 ] O 2 is proposed as a promising material to replace LiCoO 2 [3][4][5][6] due to its higher reversible capacity, good cycling performance, and structural stability. However, the lower the tap density of these layered compounds, the poorer is the rate capability.…”

“…X-ray photoelectron spectra (XPS) are recorded by a Kratos Model XSAM 800 spectrometer equipped with an Mg-Kα X-ray source (hν=1,253.6). Electrochemical impedance measurements were carried out using an Electrochemical System (Reference 600, USA) in the frequency range of 10 mHz to10 5 Hz with an excitation signal of 5 mV.…”

Nanostructured LiNi1/3Co1/3Mn1/3O2 as a cathode material for high‐power lithium‐ion battery

“…Li et al . [3] investigated the effect of synthesis methods on electrochemical performances of LiNi 1/3 Co 1/3 Mn 1/3 O 2 . They pointed out that the differences in preparation conditions resulted in the differences in the reversible capacity and rate capabilities.…”
