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

Heat-resistance of JTEKT High heat-resistant Lithium-ion Capacitor (85ºC)

Exhibiting stable performance even in high temperature environments Excellent heat resistance contributes to high output and downsizing of the system

Test video Applications

Comparison by preservation test in thermostatic chamber

Conventionalproduct

Stable operation also possible in 100ºC environments by limiting operating upper limit voltage.

This product is anticipated to be utilized in a broad range of applications requiring large current.(Trains, large trucks, large construction machinery, etc.)

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.

Since JTEKT High heat-resistant Lithium-ion Capacitor can supply the necessary large current even in low temperature environments, it is to be used in various fields.(e.g. snowmobiles, snow plows, deep-freeze storage, power source for equipment in extremely cold regions)
