House bricks become supercapacitors
New nanotechnology could allow house bricks to store electricity, according to the Guardian. At present, these bricks can only store enough energy to power small lights, but this could change.
Supercapacitors can charge and discharge much faster than lithium-ion batteries, but currently hold less capacity. However, if their capacity can be increased, they may offer a low-cost alternative to batteries.
Experts believe that adding materials such as metal oxides would store more charge in the brick, making them a commercial proposition.
Julio D’Arcy, at Washington University in St Louis, US, who was part of the research team, commented: “If so, this technology is way cheaper than lithium ion batteries…it would be a different world and you would not hear the words ‘lithium ion battery’ again.”
