文摘

“Brick-and-mortar” sandwiched porous carbon building provides highly efficient ion/electron transport pathways and structural stability for the electrode. The porous carbon building shows an ultrahigh charge/discharge rate up to 2 V s−1, high specific capacitance and outstanding cycling stability. The as-assembled symmetric supercapacitor delivers high-energy storage even at high power densities.
