BestCap®: A New Dimension in “Fast” SuperCapacitors
Written By: Scot Tripp | Dr. Arieh Meitav
Abstract:
Supercapacitors or electrochemical caps are rapidly recognized as an excellent compromise between electronic capacitors such as ceramic, tantalum and aluminum electrolytic devices and batteries. Generally, supercapacitors have energy densities several orders of magnitude higher than electronic capacitors (Table 1) and power densities significantly superior to batteries. There are, however, two negative characteristics associated with existing electrochemical capacitors, high ESR and capacitance loss when called upon to supply very short duration pulses at high current. This paper will demonstrate how the BestCap® successfully addresses both of these issues.
