Shameless plug to my recently published paper!  It's open source so you should be able to view it.   Key findings: Supercapacitors do not behave like other capacitors (obvious if you've used one).  Mainly in that their charge profile is not linear due to an internal distribution of time constants.  This means that you can charge a SC up to 1V, say, for 1s, then go open circuit and the voltage will seemingly drop, or sag.  If you do the same test but hold the 1V charge ...
Murata's small energy devices (UMA series), with high capacitance in a small package, can provide high-power backup for system or data for a long time in case of power failure. They can also contribute to a maintenance-free system because of their long cycle life characteristics.   In this demo video, further details are provided with comparisons to supercapacitors.   UMA series - Application example: Backup     Related articles: Part 1: Murata to realize Energy Harvesting ...
The Japanese car company Nissan is reusing some of the batteries from its electric cars in a new program to power cities’ streetlights. A lamp prototype of the light reborn program promo video (Image via Nissan)   As the debate on climate change and everyone’s carbon footprint continues, it is becoming evident that the world needs cleaner sources of energy, which mankind could adapt to all uses possible. That must be the driving factor in the fever automobile companies got to m ...
