The Taiyo Yuden’s cylindrical LIC (lithium-ion capacitor) is a next-generation hybrid devices that combines the strength of lithium-ion secondary batteries with conventional electric dual-layer capacitors (EDLCs) to offer an energy density 4 to 10 times greater than a typical EDLC.
Using proprietary “Lithium Pre-Dope” technology, the LICs provide an increased maximum rated voltage of 3.8 V, approximately 1.5 times higher than the 2.3 to 2.7 V of conventional capacitors. The pre-doping process stores lithium ions at the anode in advance, and enables energy to be used more efficiently and cycle life to be increased. The LIC is available in capacitances of 40, 100, and 200 F and in resistances of 50 to 150 mΩ, with operating temperatures from –25° to 60°C and 3.8 Vdc max, 2.2 Vdc min.
The hybrid devices can be used as a standalone power source or as a load-charge leveling device to increase the life of the main power source such as a dry battery or lithium primary battery. They can also be used as the main power sources for small devices such as toys, measuring equipment, and machine tools. (Samples, from $18 each available now).
