MIT researchers create concrete supercapacitors with ten times the energy storage

MIT researchers have developed concrete supercapacitors with ten times the energy storage capacity of previous designs. The new material, called electron-conducting carbon concrete (ec3), uses optimized electrolytes and manufacturing processes to create a conductive nanonetwork within concrete structures. This allows buildings, sidewalks, and bridges to potentially function as large-scale batteries. This advancement could enable structures to store and release electrical energy, offering a sustainable alternative to traditional batteries and potentially powering off-grid homes or charging electric vehicles.
