Carbon-rich polymer-derived SiCN ceramic matrix serves as a stabilizing host for sulfur cathodes due to its robust, stress-accommodating properties and well-conductive carbon network. Herein, novel SiCN-BN composites are synthesized through the annealing of alongside boric acid urea. The prepared exhibit significantly improved electrochemical performance after immobilization within resulting composites. Of particular note is material annealed at 950 °C, designated SiCN-BN-950/S. It exhibits...
Abstract In this work, a facile hydrometallurgical approach combined with heat treatment has been adopted to recycle spent graphite from retired lithium‐ion battery cells. Graphite regenerated 18 M H 2 SO 4 leaching leads high specific surface area, significant porosity and small crystallite size. The infiltrated sulfur under solvothermal conditions at 160 °C. sample containing 68 wt % of recovers capacity 224 mAh/g after 100 cycles. Furthermore, the electrode higher content 84 %,...
Graphite negative electrodes are unbeaten hitherto in lithium-ion batteries due to their unique chemical and physical properties. Thus, the increasing scarcity of graphite resources makes smart recycling or repurposing discarded particularly imperative. Herein a facile efficient hydrometallurgical process is reported effectively regenerate aged (39.5%, 75% state-of-health, SOH) scrapped (SG) from end-of-life batteries. Ultimately, first cycle reversible capacity SG1 (SOH 39.5%) improved 266...
