There are several typical failure modes of supercapacitor:
Some typical failures, such as leakage and short circuit, appear rapidly in initial operation. In general, these initial failures are usually inspected in the routine inspection of manufacturers, and they are not consid···
A supercapacitor is also known as an ultracapacitor or a double-layer capacitor. A supercapacitor differs from the ordinary capacitor in that it has much higher capacity and energy density, while at the same time having a higher power density. These characteristics make it a co···
The positive and negative materials of the super capacitor are activated carbon and aluminum, the electrolyte system with barren liquid form inside cell is is acetonitrile and salt. The main factors that affect the life are voltage and temperature. When the supercapacitor is in t···
1.Things you must know before selecting an ultra capacitor
What kind of ultracapacitor can meet your requirements? What are the critical parameters for ultra capacitor ? We will illustrate this using the ultra capacitor product system of SPS Technology as an example. The key pa···
1.The structure of supercapacitor module
The supercapacitor module consists of single cells in series or parallel connection, as shown:
single cells in series connection
single cells in parallel connection
2.The Voltage-balancing between single cells in supercapacitor module
