Renewable energy storage, particularly for wind and solar, remains a challenge. However, researchers at Chalmers University of Technology in Sweden are taking a major step toward creating an eco-friendly cement-based battery. Still in the prototype stage, the project focuses on the construction industry.
In search of sustainable and scalable materials, researchers Emma Zhang and Luping Tang, from the Department of Architecture and Civil Engineering, developed a new concept for rechargeable batteries. The process begins with a cement-based mixture containing small amounts of short carbon fibers to increase conductivity and flexural toughness. A metal-coated carbon fiber mesh—iron for the anode and nickel for the cathode—is then embedded into the mixture. This is the first concept of its kind in the world.
