For millennia, cement has been regarded as inert structural material. Here, we challenge this long-standing perception by transforming into a “living” energy device, pioneering the first microbial supercapacitor. This biohybrid system achieves 178.7 Wh/kg density and 8.3 kW/kg power density, surpassing state-of-the-art cement-based capacitors some lithium-ion capacitors. By integrating electroactive microorganisms cement, established functional charge storage network that leverages extracellular electron transfer to enable dynamic redox-active storage. exhibits cycling stability, retaining 88% of its capacitance after 5,000 cycles. Even inactivation, residual conductive networks biofilms sustain Moreover, introduce reactivation strategy, wherein an embedded microfluidic periodically supplies nutrients restore activity, enabling up 18% recovery sustaining long-term efficiency. Our findings establish new paradigm for bio-integrated, materials, paving way energy-autonomous infrastructure.
