(591f) Graphitized Candle Soot for High-Performance Dual-Carbon Battery Electrodes

This study explores the potential of catalytically graphitized candle soot as an electrode material for dual-carbon batteries. Candle soot was subjected to catalytic graphitization at 900,1200 and 1500 ^oC temperatures and Fe was used as a catalyst for graphitization. The resulting carbon materials were characterized using XRD, Raman spectroscopy, and electrochemical techniques to investigate their graphitization degree and ion transport properties. The sample at 1200 ^oC has yielded a good electrochemical performance because of the balanced disorderliness and graphitization. Then, a symmetric dual-carbon battery was assembled. The optimized electrode exhibited superior rate capability, excellent cycle stability, and enhanced specific capacity, with a working potential window up to 5.7 V. This work provides valuable insights into the tunability of carbonaceous materials for next-generation energy storage systems.
