Synthesis and characterization of LiNi0.9Co0.1O2 for lithium batteries

Irreversible Transition from GaO6 Octahedra to GaO4 Tetrahedra for Improved Electrochemical Stability in Ga-Doped Li(Ni0.9Co0.1)O2

“…LNCO exhibits a reversible capacity of ∼210 mA h g –1 (at 20 mA/g), a typical or average value for LiNi 0.9 Co 0.1 O 2 (see Table S4, Supporting Information). − It has been reported that the Li deficiency usually reduces the capacity in Ni-rich cathodes of this kind, and therefore, the slightly lower capacity here than the best one ( e.g. , 220 mA h g –1 in the literature) is probably due to the Li deficiency. , Compared with LNCO, the capacity of the doped material is slightly smaller ( ca.…”

Recent Development of Nickel-Rich and Cobalt-Free Cathode Materials for Lithium-Ion Batteries

“…The specific discharge capacity of LiNi 0.8 Al 0.2 O 2 is observed at about 150 mAh g −1 at 0.17 mA cm −2 and generates the formation of an insulating material when fully charged [58]. Among Mn-, Mg-, Al-, or Co-doped LNO materials, Li[Ni 0.9 Co 0.1 ]O 2 delivers the highest specific discharge capacity of 233 mAh g −1 at 0.1 C. However, it experiences severe capacity fading of 77% [59]. This is attributed to a developed microcrack on an entire particle when it is charged to 4.3 V, exposing the internal particle to electrolyte attack.…”

Atomic spectrometry update. Industrial analysis: metals, chemicals and advanced materials

“…Included in this number is the analysis of the cathode material LiNi 0.9 Co 0.1 O 2 prepared by co-precipitation of lithium hydroxide and Ni 0.9 Co 0.1 (OH) 2 and subsequent two-stage heat treatment in flowing oxygen. 286 The techniques of ICP-OES, XRD, SEM and cyclic voltammetry were used for the characterization. Although all the materials had a layered structure and exhibited good electrical properties, the sintering temperature was found to be critical in obtaining optimal performance.…”
