Preliminary studies on polymer electrolytes for potassium-based batteries

Future renewable energy integrated grid systems require rechargeable batteries with low cost, high safety and long cycle life. The much higher abundance of potassium compared to lithium in Earth crust indicates that rechargeable potassium batteries can represent an attractive replacement for lithium-ion counterparts. Rechargeable potassium batteries have gained tremendous attention during the past decade. However, the development of rechargeable potassium batteries is still in its infancy. In this talk, the main activities related to safe and quasi-solid polymer electrolytes investigated at the Electrochemistry Group @ PoliTO will be present. Two main approaches will be discussed, i.e. UV-curable formulations for sustainable and rapid preparation procedures and biosourced membranes coming from lignin or other sustainable biomasses.
