摘要：

MgO-templated carbons were synthesized via calcination of trimagnesium dicitrate nonahydrate by heating to 1000 degrees C at several ramping rates, followed by acid leaching of MgO. The carbons obtained at a ramping rate of 1 degrees C min(-1) exhibited a relatively large volumetric capacitance comparable to that of commercial activated carbons. In addition, they exhibited a better rate capability due to the presence of mesopores. Furthermore, the electrode densities were evaluated considering the pore volumes and void volumes between the carbon particles. (C) 2015 Elsevier B.V. All rights reserved.
