P3HT:PCBM/nickel-aluminum layered double hydroxide-graphene foam composite
What is it about?
In this paper, a simple dip-coating technique is used to deposit a poly (3-hexylthiophene) and [6, 6]-phenyl C 61 - butyric acid methyl ester (P3HT:PCBM)/nickel – aluminum- layered double hydroxide-graphene foam (NiAl-LDH-GF) composite onto a nickel foam (NF) serving as a current collector. A self-organization of the polymer chains is as- sumed on the Ni-foam grid network during the slow “ dark ” drying process in normal air
Why is it important?
The composite ex hibits a specific capacitance of 1.22 F cm − 2 at a current density of 2.0 mA cm − 2 from galvanostatic charge – discharge measurements and 0.92 F cm − 2 at a scan rate of 10 mV s− 1. The 75 % capacitance retention of the composite after 500 galvanostatic charge – discharge cycles also shows the reliable stability of the composite material for use in energy storage devices.
