BestCap® Ultra-low ESR High Power Pulse Supercapacitors

2022-08-18

◆Supercapacitors (also referred to as Electrochemical Capacitors or Double Layer Capacitors) have rapidly become recognized, not only as  an  excellent  compromise  between  “electronic”  or  “dielectric” capacitors  such  as  ceramic,  tantalum,  film  and  aluminum electrolytic,  and  batteries,  but  also  as  a  valuable technology for providing a unique combination of characteristics, particularly very high energy, power and capacitance densities.

◆There are, however, two limitations associated with conventional supercapacitors, namely: high ESR in the tens of Ohms range, and high capacitance loss when required to supply very short duration current  pulses.  BestCap®  successfully  addresses  both  of  these limitations.

◆The capacitance loss in the millisecond region is caused by the charge transfer (i.e. establishment of capacitance) being carried out primarily by relatively slow moving ions in double layer capacitors
