Mesoporous spinel manganese zinc ferrite for high-performance supercapacitors

3D Interconnected Binder-Free Electrospun MnO@C Nanofibers for Supercapacitor Devices

“…However, the bottle nick preventing their efficient use in future applications is their comparatively low energy density 5 – 7 . In this regard, transition metal oxide pseudocapacitive materials are primarily being used in SCs devices due to their high capacitance compared to carbonaceous materials 8 , 9 . While the former stores charge via rapid and reversible faradaic reactions at the electrode surface, capable of storing higher energy, the latter stores energy physically via the formation of electric double layer with lower energy storage but higher cycle life stability 10 – 13 .…”

Mesoporous ZnMoS4 as a supercapacitor electrode material with battery-like behavior

“…Such behavior indicates that the as-synthesized ZMS has an effective storage capacity with excellent rate capability. 28 In order to calculate the coulombic efficiency (Z%) of the charging/discharging process for ZMS, eqn (3) was applied using the charging and discharging times obtained from GCD measurements as follows: 24,29 Z%…”

Advanced materials and technologies for supercapacitors used in energy conversion and storage: a review

“…Recently, manganese zinc ferrite (MnZnFe 2 O 4 ) nanoneedles were successfully synthesized, with higher specific capacitance than that of MnFe 2 O 4 and ZnFe 2 O 4 . More so, the nanoneedles fabricated were found to exhibit a high surface area, powerful long-term stability and very high columbic effectiveness, which makes it suitable for supercapacitors application (Ismail et al 2018). Perovskite oxides are functional nanomaterials that have received great attention to potential applications, and it has been widely employed in the fabrication of anion-intercalation supercapacitors.…”
