A new asymmetric capacitor concept is proposed providing high energy storage capacity for only one charging direction. Size-selective microporous carbons (w<0.9 nm) with narrow pore size distribution are demonstrated to exclusively electrosorb small anions (BF<sub>4</sub> <sup>-</sup> ) but size-exclude larger cations (TBA<sup>+</sup> or TPA<sup>+</sup> ), while the counter electrode, an ordered mesoporous carbon (w>2 nm), gives access to both ions. This architecture exclusively charges in one d ...[more]
