The ØMC\ had high specific surface area (1544 m2/g) and a narrow pore size (2.7 nm), with the voltage polarization of 1.5 V, lower than that of the commonly used Super P carbon black (~1.8 V). Although the carbonate-based electrolyte was decomposed to produce Na2CO3, the ØMC\ cathode allowed reversible formation and decomposition of Na2CO3 and exhibited stable cycling behavior with low polarization for 20 cycles with a delivered capacity of 500 mAh/g at the current density of 100 mA/g.
