Activated carbon fibers derived from dryer lint via self-generated atmosphere for supercapacitor applications

Activated carbon fibers (ACFs) were synthesized using a straightforward two-step process from dryer lint microfibers in a self-generated atmosphere. During pyrolysis and activation, a CO/CO 2 environment was created based on the Boudouard equilibrium. The resulting ACFs showed a high specific surfac...

Description
Summary:Activated carbon fibers (ACFs) were synthesized using a straightforward two-step process from dryer lint microfibers in a self-generated atmosphere. During pyrolysis and activation, a CO/CO 2 environment was created based on the Boudouard equilibrium. The resulting ACFs showed a high specific surface area (1720 m 2 /g), a suitable pore size distribution, and good electrical conductivity (0.34–0.36 S/cm), promoting rapid ion transfer. ACFs demonstrated a high specific capacitance of 156.2 at 0.9 V and 180.3 F/g at 1 V. Notably, ACFs demonstrated outstanding rate capability with a power density exceeding 35 kW/kg, along with an extended cycle life of at least charge/discharge 10 4 cycles. These results are comparable to methods involving tube furnaces under inert gas with controlled heating ramps.
