Improved charge-transport and the compensation of volume-changes is crucial in technology of modern batteries, fuel-cells and transistors. Several EU/DFG-funded projects (Bat4ever within Horizon-2020, DFG) do address the chemical synthesis of novel ionomers and ionogels, used as electrolytes within large international consortia. Novel long living batteries and transistors with self-healing functions are prepared and studied as future technologies. Novel polymeric ionic liquids1-4 are studied aiming to increase ionic conductivity,1, 2 charge-transfer to the electrodes and enable a longer lifetime of the final batteries. Knowledge of ionic mobilities is transferred to interfacial transport processes such as ionic liquid gating,5 where the underlying interface and its structural changes are studied. We recently have developed self-healing and 3D-printable electrolytes.6-8
