Supercapacitors: Hierarchical Conducting Polymer@Clay Core-Shell Arrays for Flexible All-Solid-State Supercapacitor Devices (Small 29/2015)

M. Wei and co-workers report the design and fabrication of a new electrode material with a core-shell nanostructure in which a conducting polymer (polypyrrole, PPy) core and CoNi-layered double hydroxide (CoNi-LDH) shell exhibit a significant synergetic effect in supercapacitor performances. On page 3530, the obtained PPy@LDH-based, flexible, all-solid-state supercapacitor is shown to meet the requirements of both high energy/power output and long-term endurance, which can be potentially used in highly efficient and stable energy storage devices.
