MIT engineers created a carbon-cement supercapacitor that can store large amounts of energy. Made of just cement, water, and carbon black, the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.
MIT engineers have created a “supercapacitor” made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.
Carbon-based materials are paramount in advancing supercapacitor (SC) technology, particularly for flexible and industrially viable devices .

This comprehensive review has explored the current state and future directions of supercapacitor technology in energy storage applications. Supercapacitors have emerged as promising solutions to current and future energy challenges due to their high-power density, rapid charge-discharge capabilities, and long cycle life.
Moreover, the abundance, cost-effectiveness, and environmental compatibility of carbon-based materials underscore their importance in advancing supercapacitor technology across various sectors, from portable electronics to grid-scale energy management systems.
