“…Surprisingly, these kinds of CoFe 2 O 4 nanosheets exhibit a superior reversible capacity of 1147 mA h g −1 after 30 cycles and stable cycling performance. Subsequently, various 3D nanostructures of MFe 2 O 4 have also been reported, like spheres, cubes, and ordered macroporous, and yolk‐shell structures. A simple spray drying process has been used to synthesize yolk‐shell ZnFe 2 O 4 powders, TEM images in Figure e and f show the novel structure, with a minimum of two shells in each particle separated by an inner void.…”

improved LIB performance is in the electrode materials. [ 11 ] Presently, commercial anode materials mainly include graphite, which limits the lithium storage performance in terms of energy and power density due to the low theoretical capacity (LiC 6 , 372 mAh g −1 ) and low Li-ion transport rate. [12][13][14] New anode materials with higher capacities are being looked for including mixed transition metal oxide anodes. Traditional Metal Oxide AnodesNew research is constantly being carried out to reach the high requirements for LIB anodes. Various metal oxide materials such as SnO 2 , [15][16][17][18][19] Co 3 O 4 , [20][21][22][23] NiO, [24][25][26][27] Fe 3 O 4 , [28][29][30] and MnO 2 [31][32][33] are alternative potential anodes for LIBs due to their high theoretical capacities, high power density, and wide usefulness. However, metal oxides inevitably suffer from several major problems: severe volume changes during the alloying-dealloying processes, pulverization and agglomeration of primitive particles, and poor electronic conductivity that hinders the reaction with lithium during electrochemical reactions. Numerous approaches have attempted to address these challenges. One useful method is to develop the metal oxide materials into nanostructures. [ 3 ] The distinct lithium storage mechanisms and the infl uence of unique structures on the lithium storage properties of the metal oxide materials have been reported in detail. [ 5 ] A series of work on the design of various nanostructures of metal oxide materials has been subsequently carried out, for nanomaterials of different dimensions, hollow structures, and hierarchical structures. [ 5 ] Coating or combining the buffering matrix or conductive materials with metal oxide materials is another way to relieve the severe problems. [36][37][38][39][40][41][42] Various carbon materials, especially novel nanocarbon materials like carbon nanotubes and graphene nanosheets, have been widely studied as the buffering and conductive agent for metal oxide anodes. [43][44][45][46] In our previous review, [ 47 ] the signifi cant effects of graphene nanosheets on tin-based anodes were summarized in detail. It has been concluded that graphene not only contributes as a highly conductive network, but also as a fl exible supporting layer, effectively relieving the volume change and particle aggregation. In addition, different metals and metal oxides that are electrochemically active and Mixed transition-metal oxides (MTMOs), including stannates, ferrites, cobaltates, and nickelates, have attracted increased attention in the application of high performance lithium-ion batteries. Compared with traditional metal oxides, MTMOs exhibit enormous potential as electrode materials in lithium-ion batteries originating from higher reversible capacity, better structural stability, and high electronic conductivity. Recent advancements in the rational design of novel MTMO micro/nanostructures for lithium-ion battery anodes are summarized and their energy storage mechanism is compared to transit...

“…Thus, the complexes A-G are solid coordination compounds, as Xin et al 38 defined in their previous study that solid coordination compounds are stable enough to exist in the solid state only and would change to other compounds when washed by solvents. Based on the above observations, the chelating ligands instead of the primary aromatic amines shall be reacted with CoCl 2 ×6H 2 O solvent-free mechanochemically, as a continuation of this study.…”

Cobalt(II) chloride hexahydrate and primary aromatic amines were reacted by co-grinding in 1:2 metal salt to ligand ratio under solvent-free environment at room temperature. Out of 16 solid state reactions, seven cobalt-amine complexes could be established as solid coordination compounds by elemental analysis, TGA, IR, PXRD, magnetic susceptibility etc., in addition to visual observation of the color change of reaction mixture. Based on investigation of reaction and analysis of products, conclusions with outlook could be made as follows: On top of the -NH 2 group on primary aromatic amines an additional substituent group should better be at para or meta positions and not at ortho position in order to realize the solid coordination compounds. On the other hand, an electron withdrawing substituent or an extra aromatic ring is negative towards formation of the solid coordination compounds. The solid coordination Co(II)-compounds are labile in solution.
