Abstract

The concept of zero-energy device for internet-of-things requires electronics, energy convertor and storage devices. To bring that concept to the internet-of-everything, the materials should also be low-cost, recyclable, safe and environmentally friendly. In addition, all the components (electrode and electrolyte) must be printable to ensure low-cost manufacturing. Organic synthetic and bio polymers are attractive as battery electrodes due to their redox properties; but also as electrolytes due to their ability to transport ions. We summarize our recent results focusing on two material concepts for organic batteries: (i) First, a new class of electrolyte working in the regime of “water-in-polymer salt electrolyte”, which combines nonflammability, high ionic conductivity, wide electrochemical stability windows and enables aqueous organic batteries to get low self-discharge behavior (1-4). (ii) Second, we review our effort to reach low-cost lignin electrodes by either combining with conducting polymers or carbon based nanoconductors (5-7).
