Nanostructured conductive polymeric modified exfoliated graphite paper based flexible battery for wearable electronics

Abstract

Worldwide electronic waste is one of the emerging problems which can adversely affect the human and environment. The paper based flexible eco-friendly, disposable electronics battery is the excellent way to come up with the above mentioned challenge. In this work we reported the development and optimization of a cost, disposable, biodegradable, miniaturized and lightweight conductive polymer coated exfoliated graphite paper battery. Here, anode contains aluminium foil and cathode is made using electrochemically deposited anthraquinone conductive polymers on exfoliated graphite paper with a concentrated sodium chloride salt, as electrolyte. The battery shows a electrochemical response on by applying 40–50 μL of water and produces a maximum capacity of 235 mAh g−1 along with a superior cyclability of up to 500 cycles at 200.0 mA cm−2 current density. The proposed 3–4 battery connected in series powers a LED during approximately 60–90 seconds. Still continuous effort is going on for battery performance improvement. Obtained results allow to planning potential uses to low power consumptions microelectronics such as pacemakers, cosmetics, wearable biomedical devices, and electronics.
