New cement-based batteries will be able to turn the buildings to huge energy storage facilities.


Researchers have developed an efficient cement-based battery, which can be made in the form of concrete building blocks for storing energy in buildings.

Renewable energy has tremendous potential and in recent years is developing rapidly. However, one of its main problems is the rational storage of the produced electricity due to the unevenness of the inflow and consumption, especially in urban conditions. Now scientists from the Technological University of Chalmers presented a new type of cement battery, which is 10 times more efficient to previous developments.

Their battery consists of cement with an admixture of carbon fibers that improve the conductivity and strength of the material to bend, as well as meshes from carbon fiber with a metal coating, in which iron performs the anode function, and the nickel — cathode.

Tests have shown that such a battery can store 0.8 VTH per 1 liter volume. Despite the significant increase in the efficiency of this type of battery, scientists note that their research is at the initial stage and technology requires refinement. In addition to increasing the capacity, the team is looking for ways to increase the battery life so that it performs its functions throughout the life of the concrete infrastructure (minimum of 50 years).
