Science turns bricks into batteries, wanting to change both the construction industry and energy storage

Tram Ho

Since people know how to build bricks, homes for thousands of years have rarely been built with anything else. I thought there was no way to improve this ancient, solid building material …

Until scientists discovered a one-of-a-kind way to make use of bricks: through a series of chemical reactions, experts were able to turn ordinary bricks into enough energy storage tools. to light up the LED bulb.

It remains to be emphasized that much more remains to be done before we can commercialize these “smart bricks”, but scientists say the first evidence that they work opens a new future. where the walls of your home can become the energy cells themselves.

“Smart Brick” can lighten the LED light bulb.

In the scientific report, we showed that the amount of electricity is sufficiently enough to light up the emergency light bulbs – light sources are usually installed in corridors or operate sensors mounted in walls “, Julio M. D’Arcy, said an assistant professor at the University of Washington and one of the study authors.

The next step is to try to store more energy, in order to operate larger devices, such as laptops, with the power coming directly from the wall .”

According to assistant professor D’Arcy, researchers have only thought of using brick walls to store heat, but never thought of turning ordinary into batteries. ” We take advantage of the brick nature, which is a hollow web of solid matter .”

To put electricity into the brick, the researchers inserted a series of gas inserts into the block, allowing them to squeeze through microscopic holes in the brick. The gas interacts with the chemical components in the brick, creating a plastic nanofiber film called PEDOT – an effective conductor of electricity.

This process will turn a red brick into a dark blue-green luster.

Although similar in nature to energy storage batteries, D’Arcy says their “smart bricks” are more like supercapacitors – devices that differ from batteries in some ways. Although it can store a large amount of energy, supercapacitors do not hold electricity for long nor provide a stable source of energy like batteries. “The battery can keep your car going, but supercapacitors allow you to accelerate quickly when the red light is out ,” said assistant professor D’Arcy.

Scientists consider these smart bricks as the clean energy solution in the future. Although their current capacity cannot match that of li-ion batteries, optimists immediately think of homes with solar roofs, and their walls are bricks that can store electricity. power.

Science has proven that a brick can store electricity is possible, now all you need to do is optimize the material that makes up a brick, to turn it into a battery – a real smart brick.

The research has been published in the scientific journal Nature .
