Researchers at Oak Ridge National Laboratory report that adding zwitterions to polymer electrolytes significantly boosts their ionic conductivity, narrowing the performance gap with ceramic electrolytes while preserving polymers’ flexibility and ease of processing. This approach could enable safer, more manufacturable solid-state batteries by improving ion transport without the brittleness of ceramics.
Certain ceramic-based electrolytes have shown the ability to transport ions quickly, but are brittle and difficult to process into working batteries. Polymer-based electrolytes overcome these challenges, but exhibit poor ionic conductivity. Now, researchers at the Oak Ridge National Laboratory have found a path to avoiding that tradeoff by boosting the ionic conductivity of polymer electrolytes using zwitterions
