Structural Cement-Based Supercapacitors with Multifunctional Robustness for Energy Storage.

ABSTRACT: The rapid deployment of renewable energy demands cost-effective and scalable energy storage solutions. While cement-based supercapacitors offer transformative potential, their development is hindered by charge storage capacity, mechanical strength, and environmental stability. Herein, a breakthrough carbon cement supercapacitor (CCS) with exceptional electrochemical performance and excellent robustness is engineered. The porous carbon cement (CC) electrode, characterized by high strength, extremely low resistance, and high-connectivity conductive hydrogel electrolyte, is prepared by thermomechanical consolidation at 90 °C. Through in situ polymerization around sodium dodecyl sulfate (SDS)-mediated carbon black (CB) surfaces, a CB-hydrogel network is built inside the multiscale pore structu
