How to change your home into a rechargeable cement battery

Are you one of those who love to adopt cleaner and cheaper energy options? Researchers at Chalmers University of Technology in Sweden have developed a process to convert houses into giant energy storage batteries. When the technology becomes available, you can convert your home into a giant electricity storage unit. Here is what the report published by the World Economic Forum says.


How it works

• The cement battery can be constructed by mixing concrete with small amounts of short carbon fibres, according to a report published.
• These carbon fibres are embedded with a metal-coated carbon fibre mesh: iron for the anode and nickel for the cathode.
• The rechargeable cement battery could allow the whole multi-storey building to be used as a big power storage unit.
• It can be connected to solar panels

How it is different

• This cement battery can store around 10 times more energy than previously developed structures.
• The storage capacity of the new battery is more than 10 times that of a commercial battery.
• Its energy density still remains low compared to commercial batteries -- 7-watt hours per square meter.
• The volume of concrete in multi-story buildings would still make it possible to produce a significant amount of energy.
