Lamellar porous carbons (LPCs) were prepared from fluorene with Mg(OH)2 as template precursors coupled with KOH activation. The as-prepared LPCs feature a large flaky structure containing a large number of micropores and mesopores. This unique structure have a big lateral size/thickness aspect ratio and a large specific surface area of 1879 m2 g− 1. As an electrode material, the LPC shows a high capacitance of 231 F g− 1 at 0.05 A g− 1, excellent rate performance of 173 F g− 1 at 100 A g− 1, and good cycle stability with 95.93% capacitance retention after 10,000 cycles in 6 M KOH electrolyte.
