TAIYO YUDEN (U.S.A.) INC.'s new Cylindrical Lithium Ion Capacitor (LICLithium Ion Capacitor.) offers extremely large energy densityA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitors and high reliability. Combining the strength of lithium-ion secondary batteries with conventional Electric Double Layer Capacitors (EDLCElectronic double layerElectronic double layer capacitors including ultra capacitors and super capacitors. capacitors including ultra capacitors and super capacitors.), this next-generation energy device offers an energy densityA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitors 4 times greater than EDLCs.
Taiyo Yuden's hybrid LICLithium Ion Capacitor. boasts the key features of batteries (high voltage and high energy) while maintaining the traditional characteristics of capacitors (rapid chargeThe amount of electricity present upon the capacitor's plates. Also, the act of forcing of electrons onto the capacitor's plates. See CoulombA coulomb is the unit of electric charge. It is named after Charles-Augustin de Coulomb.1 coulomb is the amount of electric charge transported by a current of 1 ampere in 1 second. It can also be defined in terms of capacitance and voltage, where one coulomb is defined as one farad of capacitance times one volt of electric potential difference../discharge, high durability, safetyClass X capacitors are used in "across-the-line" applications where their failure would not lead to electric shock. Class X safety caps are used between the "live" wires carrying the incoming AC current. In this position, a capacitor failure should not cause any electrical shock hazards, rather, a capacitor failure "between-the-lines" would usually cause a fuse or circuit breaker to open. and environmental friendliness). Unlike batteries, LICs have no risk of thermal runaway and have extremely low self discharge, even in high heat environments. These LICs are much more reliable than conventional EDLCs because of this hybrid feature.
These LICs provide an increased maximum rated voltage of 3.8V (about 1.5 times higher than the 2.3-2.7V of conventional capacitors), and offer 2 times the capacity of similar sized EDLCs – making their energy densityA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitors up to 4 times higher than that of EDLCs. A higher energy densityA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitors results in fewer components needed and reduced mounting space when compared to EDLCs. One LICLithium Ion Capacitor. can replace multiple EDLCs, allowing for improved thermal design in tight spaces such as servers.
