By David L. Chandle, Massachusetts Institute of Technology October 4, 2023. 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

The Eaton PHVL-3R9H474-R supercapacitor (Figure 3, left), is a 470 millifarad (mF), 3.9 volt device with dual cells. It has a very low effective series resistance (ESR) of 0.4 ohms (Ω) to reduce conductive losses, and it can deliver a peak power of 9.5 W. It has an operating temperature range of -40°C to +65°C.
Electrostatic double-layer capacitors (EDLC), or supercapacitors (supercaps), are effective energy storage devices that bridge the functionality gap between larger and heavier battery-based systems and bulk capacitors. Supercaps can tolerate significantly more rapid charge and discharge cycles than rechargeable batteries can.
