Cement-based supercapacitors could power next-generation 'smart' buildings

Researchers have developed an energy-storing cement supercapacitor that matches commercial concrete in strength tests, according to a study in ACS Nano. The material could let buildings store renewable energy within their own structural concrete.

• Cement supercapacitor stores energy while serving as structural material
• Material held up as well as commercial concrete in tests
• Findings published in the journal ACS Nano
• Aimed at 'smart' buildings with on-site generation and storage
