The Organic Batteries Days were held on 7-8 June at the Miramar Palace in Donostia-San Sebastian. This is an annual event of reference for organic battery experts organised by UPV/EHU and Polymat. 

The topics covered included the design and synthesis of organic electroactive materials, the study of these materials in various electrochemical systems (e.g. rechargeable batteries, flow batteries) and electrolytes for organic electrodes.
