Ultrafast Catalytic Pyrolysis and Induction of High-Rate Artificial Defect Graphite under High Pressure

Abstract

Nowadays, graphite anodes have gradually disrupted the balance between commercial supply and industrial structure due to high process cost and resource consumption. Under the predicament of increasing supply risk and control, it is urgent to seek an innovation strategy to get rid of the structure limitation of the conventional high-energy consumption industrial chain. Here, we constructed a defective graphite using high-pressure catalytic pyrolysis filter paper in just 10 min. Among them, the sample containing 10% catalyst exhibited rich defects and pores (DPAG-10) after purification, achieving a high capacity of 301 mAh g −1 after 500 cycles at 4 C, which is near 4 times higher than that of natural graphite (NG). Pressure-induced high-performance defective graphite seems to be an effective process for perfecting and coordinating the dynamic network between supply and market demand in the graphite industry.
