MIT scientists have created a conductive concrete capable of storing electricity, effectively turning structural elements like walls and roads into large scale batteries. The material uses a mix of cement, water, carbon black, and electrolytes to create a nanonetwork that can hold and release power. This innovation aims to reduce reliance on traditional battery installations by utilizing the existing mass of urban infrastructure. The researchers suggest that a small amount of this material could potentially meet the daily energy needs of an average household.
