How to Use a Supercapacitor Properly

In applications where high reliability is required and energy requirements are not high, supercapacitors can be used instead of conventional batteries, or supercapacitors and batteries can be combined. Smaller and more economical batteries can be used in applications with high energy requirements. Notice for using supercapacitors properly: 1. Supercapacitors have a fixed polarity. The polarity should be confirmed before use. 2. Supercapacitors should be used at the following nominal voltages. When the capacitor voltage exceeds the nominal voltage, it will cause the electrolyte to decompose, and the capacitor will heat up, reducing capacity, increasing internal resistance, shortening life, and in some cases, causing the capacitor to collapse. 3. Supercapacitors should not be used in high frequency charging and discharging circuits, high frequency rapid charging and discharging will lead to internal heating, capacity degradation, increased internal resistance, and in some cases wil...
