Buildings and roads built with a new type of concrete could soon serve as giant batteries capable of powering homes and electric vehicles .

Scientists at Massachusetts Institute of Technology ( MIT ), who first discovered the next-generation energy storage system in 2023 , have now figured out how to make them 10 times more powerful.

The breakthrough means that the average home requires about 5 cubic metres of the material – roughly the volume of a typical basement wall – in order to meet its energy needs.

The concrete battery works by combining cement, water, carbon black and electrolytes, which combine together to create a conductive “nanonetwork” inside the material to store and release electrical energy.

“A key to the sustainability of concrete is the development of ‘mult
