Story summary

Massachusetts Institute of Technology (MIT) researchers developed electron-conducting carbon concrete (ec3) that stores and releases energy.
Storage rose tenfold, cutting daily energy from 45 to 5 cubic meters.
Focused Ion Beam-Scanning Electron Microscopy (FIB-SEM) tomography mapped nanocarbon network, enabling electrolyte penetration.
Seawater emerged as coastal electrolyte; ec3 integrates with architectural elements and could power energy-storing roads, lasting with the structure.
