Charging a supercapacitor from a 5V USB port may seem simple at first, but to charge three supercapacitors to 7V and to limit the input current to the 500 mA maximum limit on the USB port is somewhat ...

Tommy Liu builds a vehicle-mounted particulate matter monitoring system powered from harvested wind energy and an integrated ...

As the cost to produce supercapacitors (SCAPs, or ultracapacitors) continues to decline, they are carving out a niche in the marketplace between conventional capacitors and batteries. And, although ...

How to build a photovoltaic light system that operates at all times and is maintenance-free. The key role of the supercapacitor in this design. What is the "Joule Thief" circuit? Delivering ...

The LTC4425 from Linear Technology is the latest in a family of 2-cell supercapacitor chargers for addressing high peak power, data backup and "dying gasp" needs in portable and data storage ...

Researchers at UCLA have developed a new method for growing PEDOT nanofibers with exceptional energy storage capabilities. “The advance could lead to supercapacitors that can meet some energy storage ...

Scientists at the University of Central Florida have devised a new process for making flexible supercapacitors. These supercapacitors can store more energy than previous flexible supercapacitors and ...

So far our discussion summarizes the fact that in practical electronic systems a combination of different DC-DC converter topologies are used to achieve the overall efficiency, noise minimization, ...

Researchers have discovered a way to significantly improve the performance of supercapacitors by creating a novel electrolyte from an Indian tree gum. The research team showed that the biopolymer, ...
