“…The carbon source material thus plays a key role in the preparation of yolk–shell-structured materials using the spray-drying process. Nanostructured zinc ferrite (ZnFe 2 O 4 ) powders with various morphologies have been well studied as anode materials for LIBs1920212223242526. However, the electrochemical properties of ZnFe 2 O 4 yolk–shell powders have not been reported.…”

ZnFe2O4 yolk–shell powders were prepared by applying a simple spray-drying process. Dextrin was used as a drying additive and carbon source material, and thus played a key role in the preparation of the powders. The combustion of precursor powders consisting of zinc and iron salts and dextrin obtained by a spray-drying process produced the yolk–shell-structured ZnFe2O4 powders even at a low post-treatment temperature of 350°C. The ZnFe2O4 powders prepared from the spray solution without dextrin had a filled and pockmarked structure. The initial discharge capacities of the ZnFe2O4 yolk–shell and filled powders post-treated at 450°C at a current density of 500 mA g−1 were 1226 and 993 mA h g−1, respectively, and the corresponding initial Coulombic efficiencies were 74 and 58%. The discharge capacities of the ZnFe2O4 powders with yolk–shell and filled structures post-treated at 450°C after 200 cycles were 862 and 332 mA h g−1, respectively. The ZnFe2O4 yolk–shell powders with high structural stability during cycling had superior electrochemical properties to those of the powders with filled structure.

“…During these charging cycles, the reverse electrochemical reaction takes place. On the basis of pervious literatures [55][56][57], the proposed reaction mechanism of Ni 1−x Zn x Fe 2 O 4 can be listed as follows: (where the C is theoretical capacity,‫ݔ‬ is the number of the lithium ions, F is the Faradayconstant, εis the geometry structural coefficient of materials, and M is the relative molecular weight of the anode material) [58], the theoretical capacity of Ni 1−x Zn x Fe 2 O 4 materials can be list as:…”

“…), doping [26] with conductive elements, ion substitution [27], or reduction in particle size, have been employed to optimize the morphology and improve the conductivity and cycle stability [23]. Zhang et al [28] propose a PO 4 3− polyanion doping for stabilizing the energy density of Li-rich layered Li ( cathode materials with higher capacity and superior rate capability by adopting hexadecyl trimethyl ammonium bromide (CTAB) as a surfactant, which effectively alleviate the layered/spinel structure change during cycling. As a matter of fact, lithium content is also a key factor, having great impact on the morphology and electrochemical properties of cathode materials.…”

“…In the contemporary of attaching great importance to green initiative and energy saving, rechargeable lithium-ion batteries have attracted much attention in the commercial applications of electric vehicles (EVs) and hybrid electric vehicles (HEVs) by virtue of their high energy density, high working voltage, no memory effect, long cycle life, and environmental benignity [1][2][3][4][5][6][7]. Notoriously, the cathode with low capacity and high cost makes the development of lithium-ion batteries hit a bottleneck (limits).…”

The Li-rich layered Li 1 + x (Mn 0.6 Ni 0.2 Co 0.2 ) 1 − x O 2 (x = 0.14, 0.165, 0.19) cathode materials have been successfully synthesized through a one-pot facile co-precipitation route. The synthesized MCO 3 (M = Mn 0.6 Ni 0.2 Co 0.2 ) precursor mixing with Li 2 CO 3 was annealed at 500°C and calcinated at 900°C. The morphology and structure of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results indicate that the sample Li 1.165 Mn 0.501 Ni 0.167 Co 0.167 O 2 (x = 0.165) exhibits the most outstanding electrochemical performance, which may be ascribed to uniform particle size and high crystallinity. It delivers an initial discharge-specific capacity of approximately 241.7 mAh g −1 with an initial coulombic efficiency of 70.3 % at a constant density of 25 mA g −1 . A reversible dischargespecific capacity of approximately 207.2 mAh g −1 is still obtained after 100 cycles. The discharge capacities of nearly 226.8, 194.4, 158.9, 143.7, 116.8, 97.5, and 47.6 mAh g −1 can also be attained under 0.1 C, 0.2 C, 0.5 C, 1 C, 2 C, 5 C, and 10 C (1 C = 250 mA g −1 ), respectively. The Li-rich layered Li 1.165 Mn 0.501 Ni 0.167 Co 0.167 O 2 will be a promising cathode material for advanced lithium-ion batteries.
