Summary
Researchers have developed a groundbreaking 'living' microbial cement supercapacitor by embedding electroactive microorganisms into cement matrices. This biohybrid system transforms traditional inert cement into an energy storage device capable of 178.7 Wh/kg energy density and 8.3 kW/kg power density, significantly outperforming conventional cement-based capacitors. The system leverages extracellular electron transfer for dynamic charge storage, remains functional after microbial inactivation, and can be reactivated through nutrient delivery, challenging long-standing perceptions of cement as merely structural material.
