Hierarchical hollow cages of Mn-Co layered double hydroxide (LDH) are fabricated for the application of supercapacitors. The hollow cages are sized in similar to 300 nm with a unique porous structure assembled by nanosheets and a high specific surface area of 83 m(2) g(-1). As a pseudocapacitor, the as-obtained Mn-Co layered double hydroxide electrode exhibits enhanced specific capacitance, as compared to the commonly prepared Mn-Co layered double hydroxide. Moreover, the hierarchical hollow cages of Mn-Co layered double hydroxide show a good stability, with a specific capacity retention of 91.6% at the current density of 2 A g(-1) for over 2000 charge-discharge cycles. Such performance enhancement is mainly attributed to the enlarged specific surface area, improved charge transportation and ion diffusion. (C) 2017 Elsevier B.V. All rights reserved.
