Supercapacitor Cement Could Power Buildings Themselves

Scientists at the Harbin Institute of Technology and the Chinese Academy of Sciences developed a cement-based supercapacitor by printing carbon nanotube ink onto concrete. Three units wired together powered a small LED array, demonstrating that building materials can store energy. The device functions at moderate temperatures but fails below -18 degrees Celsius, with future work targeting cold-weather performance improvements.
