On page 3235, Y.-E. Miao, T. X. Liu and co-workers successfully anchor ultrathin nickel-cobalt layered double hydroxide (Ni-Co LDH) nanosheets onto the surface of nitrogen-doped carbonized bacterial cellulose (CBC-N) nanofibers to form CBC-N@LDH composite electrodes. The thus assembled asymmetric supercapacitor exhibits a high specific energy of 36.3 Wh kg−1 at a power density of 800.2 W kg−1 for potential practical applications.
