1. Introduction Electrical double layer capacitors (EDLCs), also indicated as supercapacitors, are nowadays considered as one of the most important energy storage devices [ , , ].
They have shown that devices containing silicon carbon (SiC) wires as electrodes and an operating voltage of up to 2.5 V display a capacitance retention of 80% after 10,000 cycles in a temperature range from 0 °C to 150 °C (see Fig. 1 b) [ 66 ].
The experimental results show that the charge/discharge rate has a significant impact on the temperature rise of the LIC cell, which affects the performance of the capacitor. Therefore, it is important to study the thermal characteristics of LIC cells discharged at high-rate to guide the thermal management of batteries.
Over a floating time of 40 h the EDLC cycled up to 3.5 V loses all its capacitance, whereas the one cycled up to 2.5 V displays a good capacitance retention. The failure of the 3.5 V EDLC is also visible in an increase in resistance over time which can be related to degradation processes occurring in the cell.
