AI Customer ServiceA lithium-ion capacitor (LIC) is a hybrid energy storage device combining the energy storage mechanisms of lithium-ion batteries (LIBs) and electric double-layer capacitors (EDLCs), and it incorporates the advantages of both technologies and eliminates their drawbacks. This technology has shown a long cycle life in a wide temperature range.
To reduce capacitance fading during power cycling tests, and to improve the useful life of SCs, it is recommended to introduce rests times during SC cycling, to discharge the SC to a low voltage, and to increase the case temperature during rest times for as long as possible with not exceeding the products limits operation. 5.
In terms of variations in ageing rate, the decrease in capacitance during nonstop cycling test is faster than the increase in resistance . Thus, after 300 h of continuous cycles, the relative decrease in capacitance is approximately 14.4%, whereas the relative increase in resistance is approximately 12%.
As long component lifetime is a requirement for many applications, a computer-controlled test rig has been built to validate supercapacitor lifetimes to manufacturer's specifications. The test rig is also utilized to determine the effect of temperature on supercapacitor parameters and investigate application lifetime.
As the cycling test includes a rest, the capacitance is recovered. The initial capacitance C (1, n) after a long rest time can be calculated using Eq. (6): (6) C ( 1, n) = a · exp - Δ t τ 1 + b · exp - Δ t τ 2 where Δ t is the rest period between cycle series n and n + 1.
The capacitance recovery observed during each power cycling interruption can be characterised, for the entire ageing test, in terms of the magnitude Δ C and the time Δ t corresponding to the transient during which the capacitance decreases to the same value as that observed just before the interruption, as shown in Fig. 5.
