Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Storage

Background:

  • Carbonaceous materials are key components for rechargeable alkali-ion battery anodes.
  • Developing high-performance and cost-effective anode materials is crucial for advancing battery technology.

Purpose of the Study:

  • To investigate the potential of C.I. Pigment Violet 19 (PV19) as a carbon precursor for alkali-ion battery anodes.
  • To characterize the electrochemical performance of anodes derived from pyrolyzed PV19.

Main Methods:

  • Fabrication and electrochemical testing of anode materials in lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs).
  • Spectroscopic analyses to elucidate ion storage mechanisms and kinetics.

Main Results:

  • PV19-600 anodes exhibited exceptional rate performance and cycling stability in LIBs (554 mAh g⁻¹ over 900 cycles at 1.0 A g⁻¹).
  • PV19-600 anodes demonstrated good rate capability and cycling behavior in SIBs (200 mAh g⁻¹ after 200 cycles at 0.1 A g⁻¹).
  • Spectroscopic data revealed a surface-dominant storage mechanism facilitated by nitrogen- and oxygen-containing porous structures.

Conclusions:

  • Pyrolyzed PV19 is a promising precursor for fabricating high-performance carbon anodes for alkali-ion batteries.
  • The nitrogen- and oxygen-rich porous structure enhances alkali-ion storage through surface-dominant processes.
  • This study offers a new pathway for developing advanced anode materials from organic pigments.
