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.
