Polyvinylpyrrolidone-derived carbon-coated magnesium ferrite composite nanofibers as anode material for high-performance lithium-ion batteries

Spinel ferrite (AFe2O4)-based heterostructured designs for lithium-ion battery, environmental monitoring, and biomedical applications

“…6c and d). 101 Similarly, using a one-dimensional MgFe 2 O 4 material, Luo et al 102 109 were successfully fabricated and presented excellent electrochemical storage performance in terms of reversible capacities, cycle lives, and rate capabilities compared with pure SFNs. Herein, to explain the positive changes in electrochemical performance, it is assumed that the unique carbon-coated electrode structure provides a higher surface area along with numerous reactive sites and short transport pathways for both electrons and Li + .…”

Polyimide-derived carbon nanofiber membranes as free-standing anodes for lithium-ion batteries

“…In terms of the electrospinning precursors for CNMs, high carbon yield and excellent spinnability are the prime factors to be considered. In previous studies, the raw materials of electrospinning CNMs have rich resources, such as polyacrylonitrile (PAN), [28][29][30] pitch, 31 polyvinylpyrrolidone (PVP), 32 polyimide (PI), 33 and so on. Typically, PAN is the most commonly used material as carbon precursor due to its relatively low cost, high elastic modulus and high carbon residue rate.…”

Preparation and Electrochemical Properties of Mesoporous NiFe2O4/N-Doped Carbon Nanocomposite as an Anode for Lithium Ion Battery

“…Moreover, it is possible to exist a confinement effect between the metal elements compared with the single-metal oxides (Bai et al, 2014;Wang et al, 2014). Compared with the Fe 2 O 3 , porous NiFe 2 O 4 nanostructures would deliver higher capacities and exhibit a longer cycling ability (Wang et al, 2016), which gains a theoretical capacity of 915 mAh g −1 (Luo et al, 2017). However, NiFe 2 O 4 has a main weakness due to the large volume change during lithiation/de-lithiation process which results in rapid capacity loss and poor cycling life (Xiao et al, 2017).…”
