报告摘要：
Rational design of porous carbon electrodes is critical for the development of capacitive technologies, including electric double layer capacitors (EDLCs) and capacitive deionization (CDI). Ionic liquid based EDLCs using nanoporous carbon as electrodes hold promises for future energy storage devices with high energy density, but their power performances are limited by the high viscosity and large ion size of ionic liquids. Understanding the relationship of the carbon pore size, the ion diffusivity, and the energy/power density is critical for the advancement of ionic liquid based EDLCs. CDI is an emerging technology for the efficient desalination of brackish and saline waters. Owing to the similar electrochemical mechanism of CDI and EDLCs, mesoporous carbons with structural properties favoring high capacitance, such as high surface area, have been extensively used in CDI devices. However, efficient electrosorption in CDI relies on the unimpeded transfer of salt ions from the bulk water to carbon pore surfaces. Improving mesopore accessibility by shortening pore lengths and opening pore apertures is expected to facilitate the ion diffusion and promote the CDI performances. In this talk, we will demonstrate the synthesis of single-layered mesoporous carbon sandwiched graphene nanosheets with tunable mesopore structures and investigate the structure-performance correlations in both EDLC and CDI systems.
