摘要：

The low decomposition voltage (~1.23 V) of water enormously restricts the workable voltage of aqueous symmetrical supercapacitors (SSCs), which correspondingly limits the energy densities and frustrates the commercialization of aqueous SSCs. Herein, the voltage window of an all-solid-state symmetrical supercapacitors (ASSC) can be extended via employing a novel self-supporting hybrid electrode constructed by coupling FeNiCo oxides with Ni(pyrithione)2 on FeNi foam (denoted as NiPT@FeNiCo oxides/FNF) as both cathode and anode, which was synthesi...
