“…An overview of all determined ionic and electronic resistances and conductivities of MgSc 2 Se 4 is given in the Supporting Information in Tables S3 and S4. For state‐of‐the‐art alkali solid‐state electrolytes, the relationship of the electronic conductivity to the ionic conductivity ( σ e / σ i ) is within 10 −4 –10 −6 % ,. The Ti‐doped materials achieve values between 0.96 % ( x =0.0075) and 490 % ( x =0.15), which means that the electronic conductivity is already extremely high (compared with the ionic conductivity) for the lowest Ti‐doping level, and for MgSc 1.67 Ti 0.15 Se 4 it even exceeds the ionic conductivity.…”

“…Due to the large segregation of compositions and the appearance of hetero phase, the cathode material prepared with solid state reaction method has poor electrochemical performance. For example, Xia et al [29] explored the effect of the sintering conditions on electrochemical properties of NCM622 cathode materials when they used the segmented sintering solid state reaction method and indicated that a larger particle size and severer agglomeration were observed and occurred at 850 ∘ C ( Figure 5(a)). As seen in Figure 5(b), with increasing the sintering time, the primary particle size of cathode materials did not become large obviously, but their electrochemical performance reduced.…”

Due to the advantages of high specific capacity, various temperatures, and low cost, layered LiNi0.6Co0.2Mn0.2O2 has become one of the potential cathode materials for lithium-ion battery. However, its application was limited by the high cation mixing degree and poor electric conductivity. In this paper, the influences of synthesis methods and modification such surface coating and doping materials on the electrochemical properties such as capacity, cycle stability, rate capability, and impedance of LiNi0.6Co0.2Mn0.2O2 cathode materials are reviewed and discussed. The confronting issues of LiNi0.6Co0.2Mn0.2O2 cathode materials have been pointed out, and the future development of its application is also prospected.

“…Then, the uniformly mixing samples were sintered at 850℃ for 12h, following with natural cooling to room temperature according to our previous work. 41,42,43 The synthesized NCM523 materials with particle size of 9 µm, 6 µm and 3 µm were denoted as D9, D6 and D3, respectively. In particular, they were also compared with the mixed materials as the contrast samples.…”

Electrode material with high tap density and high specific volumetric energy is the key of large-scale industrial applications for lithium ion battery industry, which faces huge challenges. LiNi 0.5 Co 0.2 Mn 0.3 O 2 cathode materials with different particle sizes are used as the raw materials to study the effect of mass ratio of mixed materials on tap density and electrochemical performance of mixed materials in this work. Physical and electrochemical characterizations demonstrate that the tap density of mixed powders with different particle size is higher than those of materials with single particle size. The tap density of as-prepared material has a trend of decrease with the increase of the ratio of 9 µm particle size in the materials. The highest tap density among all kinds of materials reaches up to 2.66 g cm -3 . Besides, the mixed material with mass ratio of 7:2:1 has bigger specific surface area as well as it presents better cycle behaviors and rate capability than other materials. The specific volumetric capacity of this mixed sample reaches up to 394.3 mAh cm -3 with 1 C rate charge/discharge, and it has the advance of 8.5 %, 22.2 % and 40.6 % than any single particle size of 9 µm, 6 µm and 3 µm, respectively, which contributes to the industrial production of LiNi-Co-Mn-O cathode materials for lithium ion batteries.
