Improved strategies for ammonium vanadate-based zinc ion batteries

Abstract

Aqueous zinc ion batteries (ZIBs) are becoming increasingly popular as a new form of resources electrochemical energy storage due to their high safety, affordability, availability of natural zinc resources, and...

Roadmap on multivalent batteries

“…Enhancing the electronic conductivity of cathode materials is imperative for advancing ZIBs. Many cathode materials exhibit suboptimal electronic conductivity, necessitating the inclusion of numerous conductive species, albeit at the expense of active mass loading [289]. Developing cathode materials with improved electronic conductivity becomes essential to bolster the overall efficiency and performance of ZIBs.…”

An ammonium vanadate/MXene nanocomposite for high-performance ammonium ion storage

“…During the intercalation, the NH 4 + ion rotates to move forward inside the electrode structure, with the hydrogen bonds between the NH 4 + ion and the host dynamically breaking and forming back and forth, leading to high power density and long-term cycling lifetime. 6,7 Various non-metallic charge carriers, such as protons (H + ), hydronium (H 3 O + ), and ammonium (NH 4 + ) ions have physical characteristics that could be advantageous for electrochemical systems. 8,9 Among those, NH 4 + ions as charge carriers forming mildly acidic electrolytes are particularly appealing, whereas protons or hydronium ions result in a more reactive acidic environment that may corrode the electrodes.…”

“…1,2 Therefore, efficient and affordable energy-storage systems are highly desirable. [3][4][5][6][7][8][9][10] Researchers are searching for cost-effective and potentially safer alternatives to the well-known lithium-ion battery (LIB) technology. [11][12][13] In particular, aqueous electrolyte batteries have great potential as stationary battery technology.…”
