Supercapacitor cement is a real laboratory research direction, but it is not yet a home battery or an energy-storing foundation you can buy. Researchers combined cement, water and conductive carbon black to make electrodes that store electrical charge. Their small devices have powered an LED, and a later paper record reports a stacked prototype. The much larger idea—using foundations or other concrete structures to store renewable electricity—remains prospective.
How can cement store electricity?
The material is designed as a supercapacitor electrode, not as an ordinary cement battery. As cement hydrates, its pore structure helps organize conductive carbon black into a connected network. The carbon network provides a large internal surface where charge can be stored. Mobile ions in an electrolyte carry charge between electrodes; in the MIT description, two electrodes are separated by a thin gap or insulating layer and saturated with an electrolyte such as potassium chloride.

The 2023 study argues that the material’s capacity behaves as an intensive quantity and reports self-similarity in high-rate performance. In practical terms, the authors suggest that useful electrode behavior may persist as the material is scaled. That is a research finding that motivates larger tests—not proof that a foundation or road will perform like a small cell. The 2023 paper in PNAS describes the material and its measured properties.

How much energy could supercapacitor cement store?
Chanut and colleagues estimated a maximum volumetric capacity of 20–220 watt-hours per cubic metre (Wh/m³) in their 2023 PNAS paper, depending on the specific surface area of the carbon black used. This is a research estimate across materials, not a field measurement of a building-scale installation.

MIT News illustrated the estimate with a calculation: about 45 cubic metres of high-surface-area carbon-black-doped concrete for roughly 10 kilowatt-hours, framed as approximately one average day of household electricity use. That is a projected household-scale example, not a tested residential foundation or a guarantee for a home’s actual demand. MIT’s July 2023 explanation gives the example and describes the early devices.
What has actually been demonstrated?
The 2023 laboratory cells
MIT reported that the first devices were small cells about 1 centimetre in diameter and 1 millimetre thick, producing about 1 volt each. Researchers connected three cells to light a 3-volt LED. This demonstrated charge storage and delivery at small scale; it did not demonstrate a building-scale energy system.

The later stacked-layer prototype
A 2025 PNAS search-result record reports a stacked-layer prototype measuring about 0.003 cubic metres, with a 12-volt output and a volumetric capacity of 304 Wh/m³. These figures indicate further laboratory progress, but the available record does not establish the test conditions, cycle life, structural performance or durability. They should not be treated as a validated result for a building installation. The 2025 PNAS record is the source for the surfaced prototype metrics.

Potential uses discussed by the researchers and MIT include storing renewable electricity in building foundations or isolated shelters, and eventually integrating storage into roads or wind infrastructure. These are proposed applications, not existing installations established by the cited sources. MIT also describes the possibility of heating carbon-laced concrete through electrical resistance, another potential use rather than a demonstrated building service.

A supercapacitor can be suited to rapid charge and discharge, but the available evidence does not show that this material can replace a household battery for sustained practical service. The cited sources do not establish a commercially available product, a building-code approval, installed cost, field-maintenance needs or operating lifetime in a structure.
Why adding more carbon black is not a simple fix
More carbon black can increase charge-storage capacity, but it can also reduce concrete strength. The design challenge is to meet the structure’s mechanical requirements while improving electrical performance. MIT identified around 10% carbon black as a potential balance for structural applications in the formulation context it described. It is not a universal construction recipe or a recommendation to add that proportion to ordinary concrete.

Before judging the technology against conventional batteries or other storage, several measures would need to be compared under equivalent conditions: energy per volume, charge and discharge power, load-bearing performance, installed-system cost, service life, maintenance and readiness for deployment. The cited sources provide research-level capacity estimates and small-device demonstrations, but not comparable building-scale durability, field performance or installed costs.

Supercapacitor cement offers a way to investigate whether a widely used structural material can also store and release electrical charge. The 2023 work demonstrated small cells; the reported 2025 prototype points to continued laboratory development. Scaling the concept into a useful foundation, road or other working structure still requires evidence about mechanical performance, durability, cost and real-world operation. For now, it is a promising research concept—not a ready-made way to store a home’s solar electricity.
