A lamellar V₂O₃@C composite for aluminium-ion batteries displaying long cycle life and low-temperature tolerance

Abstract

Rechargeable aluminum-ion (Al-ion) batteries have important potential for fast charging and safe energy-storage systems. Here, we develop a composite composing of lamellar V2O3@C nanosheets, which displays high electrochemical properties as...

A metal-free all-organic ammonium-ion battery with low-temperature applications

“…Therefore, there has been intense interest in studying alternative metallic charge carriers in batteries, such as Na + and K + , as well as multivalent metallic ions including Al 3+ , Zn 2+ , Mg 2+ , etc. [8][9][10][11][12] However, batteries based on these metallic charge carriers are limited by high electrostatic attraction or repulsion between the multivalent ions and electrode, electrode corrosion by electrolyte, active material dissolution, self-aggregation and phase change during (de) intercalation.…”

Gas-template directed in situ synthesis of highly nitrogen-doped carbon nanotubes with superior sulfur compatibility and enhanced functionalities

“…For the former, there is a need of precursor optimization, and the synthesis usually experiences rather harsh and complicated procedures such as high-temperature (∼1300 °C) CVD, 12 metal-catalyzed growth, 13 laser ablation, 14 and others that involve special instruments. 15 As for the latter, the doping is realized by high-temperature treatment of CNTs with nitrogen precursors such as NH 3 , pyridine, and pyrrole. 16 However, the above synthetic techniques usually suffer from drawbacks such as low degree of N doping, severe loss of edge nitrogen and abundant formation of structural defects, making the resulted N-doped CNTs unsatisfactory in performance.…”
