Phys.org  November 9, 2021 Polyaniline (PANI) is conductive and can be used as the electrode in a supercapacitor device, storing charge by trapping ions. To maximize energy storage, an international team of researchers (UK, Brazil) developed a novel method of depositing a thin layer of PANI onto a forest of conductive carbon nanotubes. This composite material makes an excellent supercapacitive electrode. However, as the composite is made up of different materials, it is difficult to separate and fully understand the complex processes which occur during charging and discharging. The researchers used Distribution of Relaxation Times analysis technique to examine complex […]
