Conférence Pr Reverant Crispin

vendredi 24 novembre 2023 de 11:00 - 12:00

Towards printed lignin-based batteries

Pr Reverant CRISPIN

Linköping University, Sweden


Xavier Crispin obtained his PhD in 2000 with Prof. J.L. Brédas (University of Mons, Belgium), postdoc at Linköping University with Prof. W.R. Salaneck. In 2004, Xavier joined the Laboratory of Organic Electronics headed by Prof. M. Berggren. For his work on organic thermoelectrics, he received the ERCstarting grant (2011), the Tage Erlander Prize (2012) and the Göran Gustafsson prize (2016). Since 2014, he is appointed as a Professor in Organic Energy Materials. In 2019, he became vice-director of the national program Advanced Functional Materials. He is cofounder and scientific advisor of Ligna Energy AB (2017), ParsNord AB (2020), and Cellfion AB (2021).

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).
