Northwestern researchers develop cell-inspired gel that stores energy for months and releases it on demand

Northwestern University researchers report a new material that mimics cellular energy storage. The material starts as a liquid and solidifies into a gel rich in stored power. It can retain captured energy for several months without significant loss. When triggered, the gel releases the stored energy on demand. The approach draws inspiration from how biological cells manage energy. Potential applications include remote sensors, off‑grid power, and emergency backup systems. The study demonstrates a scalable pathway for long‑term energy storage. Further work will test durability and integration with existing power technologies.
