3 Terms and definitions

The following terms are defined in GB 6944 and the "Recommendation on the Transport of Dangerous Goods, Model Regulations" (hereinafter referred to as the "Model Regulations") and definitions apply to this document: 3:1 supercapacitorsupercapacitor Between ordinary capacitors and batteries, at least one electrode uses a double electrical layer to store energy: During constant current charging or discharging, The time versus voltage curve is usually approximately linear for electrochemical energy storage devices:

Note: In this document, the term "capacitor" is used when special emphasis on "supercapacitor" is not required:
