High heat-resistant Lithium-ion Capacitor
Highest heat resistance in the industryAble to be used in ranges difficult to date due to the need for cooling.
Also supports self-heat generation during large current charge/discharge・Also shows excellent durability against deterioration caused by self-heat generation during large current charge/discharge.
・Achieves a compact system through elimination of cooling and reduction of cooling space.
Supportshigh temperatures
Supportslarge current
Stable output and capacitance No cooling required even on systems with large current
Comparison of float charging resistance (85°C, 3.8V) Self-heat generation behavior during large current charge/discharge (capacitor simple lamination with NO cell clearance)
Increase rate of internal resistance during float charging test (85ºC, 3.8V) Reduction rate of discharging capacity during float charging (85ºC, 3.8V) Performance change during large current charge/discharge test

Test video ApplicationsA stable supply of large current is possible as the electrolyte liquid does not freeze even at -40°C.
[ Test overview ]
Electrolyte liquid was stored in the glass jars on the left and right, and cooled to -40°C. The conventional electrolyte liquid (right) froze, however JTEKT’s electrolyte liquid (left) did not.
