Multi-electron bipolar-type organic molecules for high-capacity dual-ion zinc batteries

Abstract

Organic materials featuring element sustainability and functional tunability have currently sprung up as viable cathode alternatives toward zinc ion batteries. Nevertheless, organic materials generally suffer from performance deficiency such as...

Bipolar conjugated microporous polymer anchoring graphene hybrids for high-performance zinc–organic batteries

“…S22, † the appearance and disappearance of the akes in the C and E state SEM images, as well as the alternation of the elements Zn and S in the EDS mapping, suggest the efficient and reversible dual-ion storage mechanism of Zn 2+ and CF 3 SO 3 − ions. 43 The storage mechanism of rGO@CMPs is described in Fig. 4a.…”

Recent Progress on Cathode Materials for Rechargeable Zinc Ion Batteries

“…[139] Hu et al prepared a RZIBs using anthraquinones and indanthrone as cathode materials, which extended the conjugated system and improved the high voltage durability due to the p-type NÀ H bridging in the N-type anthraquinone network, resulting in a designed Zn//IDT cell with a specific capacity of 238 mAh g À 1 at 0.2 A g À 1 . [140]…”

“…As cathode materials for RZIBs, conjugated polymers have the possibility to inhibit the dissolution process, and their network structure is easy to carry out the rapid diffusion of zinc ions, but their structure is easy to be damaged and deactivated during charge-discharge process. [121][122][123][124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139][140] On the other hand, many reported inorganic cathode materials are prone to disproportionate ionic reactions which cause dissolution of the ions in the electrolyte and degradation of the cycling performance. The formation of IOC cathode materials combining conjugated polymers and inorganic cathode materials become a way to further improve the performances of RZIBs.…”

Synthesis of surfactant-assisted nickel ferrite nanoparticles (NFNPs@surfactant) to amplify their application as an advanced electrode material for high-performance supercapacitors

“…reported organic materials showing elemental stability as well as functional tenability for use as cathodes for energy storage devices, exhibiting signicant electrochemical performance. 14 There are several unique methods for the syntheses of NiFe 2 O 4 nanoparticles, including solid state reaction method, 15 reverse micelle method, sol-gel method, 16 hydrothermal techniques, 17 shock wave method, 18 aerosolization, 19 microwave hydrothermal method, 20 ultra-sonic hydrothermal method, 21 sonochemistry 22 and ball milling method. 23 The basic drawbacks of these techniques include the precision in maintaining the particle size and distribution.…”
