India, Aug. 5 -- Supercapacitor is a high-capacity energy storage device, which exhibits high power density, long cyclic stability, and rapid charging/discharging efficiency. The power density of supercapacitors is about 1,000 higher than rechargeable batteries.

In a separate report on electronic components, for passive components, I had stated that India should focus more on localizing capacitors first, besides resistors, inductors, transformers, etc.

This article is to gauge interest on whether readers follow electronic components that are so necessary for India's semiconductor and electronics industries.

We have the electric double-layer capacitors (ELDC), pseudo-capacitors -- with metal oxides or conduct polymers for higher energy ...
