Samwha Capacitor - Energy Storage Supercapacitor - EDLC (ESD-SCAP)

• EDLC (ESD-SCAP)

• 

• 
• 

• EDLC, known as electric double layer capacitor, is an electrochemical capacitor in which an electric charge is stored performing adsorption and desorption of the ion in electrolyte at the electrode/electrolyte interface.
  It has the following features: (1) low internal resistance, (2) high power density, (3) high reliability, and (4) wide operating temperature range(-40 ~ +60℃). Its energy density is typically hundreds of times greater than electrolytic capacitor and it also has a much higher power density than Li-ion battery.
