A series of O3-phase NaFex(Ni0.5Mn0.5)1–xO2 (x = 0, 0.1, 0.2, 0.3, 0.4, and 1) samples with different Fe contents was prepared investigated as high-capacity cathodic hosts Na-ion batteries. The partial substitution Ni Mn in the lattice can greatly improve electrochemical performance structural stability. NaFe0.2Mn0.4Ni0.4O2 cathode an optimized content x 0.2 deliver initial reversible capacity 131 mAh g–1, a greater than 95% over 30 cycles, high rate 86 g–1 at 10 C voltage range 2.0–4.0 V....
High-energy-density lithium-ion batteries (LIBs) that can be safely fast-charged are desirable for electric vehicles. However, sub-optimal lithiation potential and low capacity of commonly used LIBs anode cause safety issues energy density. Here we hypothesize a cobalt vanadate oxide, Co2VO4, attractive material fast-charging due to its high (~ 1000 mAh g-1) safe 0.65 V vs. Li+/Li). The Li+ diffusion coefficient Co2VO4 is evaluated by theoretical calculation as 3.15 × 10-10 cm2 s-1, proving...
Multilayered nanocrystalline SnO2 hollow microspheres (HS−SnO2) were synthesized by chemically induced self-assembly in the hydrothermal environment. First, multilayered spherical SnO2−C composite was produced through a condensation polymerization and carbonization of sucrose accompanied hydrolysis SnCl4 reaction. Then, HS−SnO2were obtained removal carbon via calcination. The as-prepared HS−SnO2 exhibit good electrochemical performance as anode material lithium ion batteries. Since this...
Three types of FeF3 nanocrystals were synthesized by different chemical routes and investigated as a cathode-active material for rechargeable lithium batteries. XRD TEM analyses revealed that the as-synthesized samples have pure ReO3-type structure with uniformly distributed crystallite size ∼10 to 20 nm. Charge−discharge experiments in combination cyclic voltammetric evidence demonstrated nanocomposite electrode can realize reversible electrochemical conversion reaction from Fe3+ Fe0 vice...
Mg-doped Li[Li0.2–2xMgxCo0.13Ni0.13Mn0.54]O2 is synthesized by introducing Mg ions into the transition-metal (TM) layer of this layered compound for substituting Li through a simple polymer-pyrolysis method. The structural and morphological characterization reveals that doped are uniformly distributed in bulk lattice, showing an insignificant impact on structure. Electrochemical experiments reveal that, at doping 4%, Li[Li0.16Mg0.04Co0.13Ni0.13Mn0.54]O2 electrode can deliver larger initial...
Sodium-ion batteries (SIBs) are promising candidates for large-scale energy storage systems due to the abundance and wide distribution of sodium resources. Various solutions have been successfully applied revolve large-ion-size-induced battery issues at mid-to-low current density range. However, fast-charging properties SIBs still in high demand accommodate increasing needs large grid scales. Herein, a core-shell Co2VO4/carbon composite anode is designed tackle problem SIBs. The synergetic...
