Superior Cycling Stability

Hierarchically porous carbons are obtained by a facile process of carbonizing the precursor of diblock copolymer xPS-[Formula: see text]-polymethylmethacrylate (PMMA). In the diblock copolymer, there is a carbon source of cross-linked polystyrene (xPS) and a sacrificial block of PMMA. The atom transfer radical polymerization was used to synthesize the diblock copolymer with controlled molecular weight and narrow polydispersity in dimethylformamide at 120∘C. The obtained hierarchically porous carbons (HPCs) exhibit remarkable electrochemical properties, such as higher specific capacitance of 204[Formula: see text]F[Formula: see text]g[Formula: see text] at the current density of 0.5[Formula: see text]A[Formula: see text]g[Formula: see text] in 6[Formula: see text]mol[Formula: see text]L[Formula: see text] aqueous KOH electrolyte. In addition, it also presents an excellent rate performance of 64% capacitance retention as the current density increases to 10[Formula: see text]A[Formula: see text]g[Formula: see text] and a superior cycling stability of 98% capacitance retention after 5000 cycles at the current density of 1[Formula: see text]A[Formula: see text]g[Formula: see text].
