文章摘要：The electrode materials with advanced surface structure and architecture that effectively wet electrolyte and promote (ad/de)sorption of electrolyte ions. It remains a great challenge to improve electrode surface wetting properties when submersed in electrolyte. Herein, we report a novel electrolyte-philic electrode material (EEM) involving interconnected hierarchically porous carbon (IHPC) and grafted electrolyte-philic polymer chain brush by the surface initiated electrochemical mediated atom transfer radical polymerization (SI-eATRP), named as EEM-g-Polymer, which possesses higher capacity, almost 3 times larger than that of pristine one. And the selectivity and responsiveness of polymer brush can be tailored to different electrolyte environments. The EEM-g-PVP (or EEM-g-PSSNa) negative electrodes are combined with Ni(OH)2 positive electrodes for the fabrication of asymmetric supercapacitors. Notably, the device presents a maximum energy density of 27.8 Wh/kg (or 27.5 Wh/kg) when the power density is 351 W/kg (or 314 W/kg),and the capacitance retention is 70.0 % (or 65.0 %) of the initial capacitance value after 10000 cycles.
