What is another word for electric double-layer capacitor?
Pronunciation: [ɪlˈɛktɹɪk dˈʌbə͡llˈe͡ɪə kəpˈasɪtə] (IPA) 
The term "electric double-layer capacitor" refers to a type of energy storage device that uses two layers of electric charge to store and release energy. There are several other terms commonly used to describe this type of capacitor, including supercapacitor, ultracapacitor, and electrochemical capacitor. These terms all refer to the same type of device and are often used interchangeably. While they may have slightly different technical definitions, they all share the ability to store and release energy quickly, making them ideal for applications that require high power density and rapid charging and discharging cycles. Whether you call it a supercapacitor or an electrochemical capacitor, the technology behind this type of energy storage is rapidly advancing and is poised to play an increasingly important role in the future of energy storage and conversion.
