- Researchers from Aarhus University have developed a living supercapacitor by integrating electricity-generating microbes into cement.
- The biohybrid supercapacitor can store electricity and regenerate its capacity when fed nutrients, potentially enabling energy-autonomous buildings.
- The material uses Shewanella oneidensis bacteria, which transfer electrons to external surfaces, creating a network for energy storage and release.
- An integrated microfluidic network delivers nutrients to sustain or revive bacterial activity, recovering up to 80% of the original energy capacity.
- The cement retains functionality under extreme temperatures and, when connected in series, can power devices like an LED light.
- The technology could be scaled for use in walls, foundations, or bridges, providing sustainable and affordable energy storage.
- Unlike conventional batteries, the material is made from abundant, inexpensive components and environmentally friendly bacteria.
