Abstract

A thin nanosheet of mesoporous cobalt carbonate hydroxide (MPCCH) has been fabricated from a CoAl-LDH nanosheet following removal of the Al cations by alkali etching. The basic etched electrode exhibits enhanced specific capacitance (1075 F g−1 at 5 mA cm−2) and higher rate capability and cycling stability (92% maintained after 2000 cycles).
