At the beginning of 2020, for the first time ever, renewable energy was able to cover more than half of the electricity consumed in Germany. But the more important renewable energy sources become, the more urgent is the need to store the electricity pro­duced in this way. Green energy could then also be used when the sun is not shining on the solar panels or no airflow is driving the wind turbines. To achieve this, suitable energy sto­rage devices are indispensable. Researchers at the Friedrich Schiller University Jena (Ger­many) have recently developed promising new polymer electrolytes for redox flow batteries, which are flexible, efficient, and environmentally friendly.
