Recently, 45 concrete manufacturers in Japan jointly set up an industrial association to create a new type of building material, electric storage concrete, which can store energy . The electronic conductive concrete developed
by Huize High Pressure Concrete Company of Japan and MIT of the United States can be charged and discharged without any chemical reaction.
This material can store and release electricity like a battery, and is expected to be used in buildings, sidewalks and other infrastructure. It is mainly composed of cement, water, ultrafine carbon black and electrolyte, of which the latter two are core materials. Ultrafine particles in
carbon black can form a conductive nano-network inside concrete, making the material conductive, while electrolytes can carry charges. When the two materials are mixed with cement and water, they form a concrete that can store and release electricity, similar to supercapacitors or large batteries .
This means that concrete is not only used as a structural bearing building material, but also has the function of energy storage. It has become a new material for the integration of building and energy. It can be used to build walls, floors, roads and bridges, so that these buildings can store electricity and supply power directly.
The research team also built a miniature EC3 arch to verify its core technology. The structure can not only bear the load, but also use the stored electricity to power the small led lamp; when the load increases, the led lamp will flash, which also shows that the material can achieve self-monitoring.
When our bridges, buildings and roads become the storage of energy, it means that distributed energy, energy networks and low-carbon societies are one step closer.
Therefore, electricity storage concrete has great potential in the future.
