Lithium Ion Capacitor

Discharge Performance

LIC front LIC front

In August 2007, JSR Corporation launched JM Energy which is dedicated to the development, manufacture and marketing of its Ultimo, Lithium Ion Capacitor (LIC). A capacitor is an electrical storage device that stores or releases electricity through rapid electrostatic reactions. Compared with a battery that stores electricity through slow chemical reactions, a capacitor makes it possible to charge and discharge electricity almost instantaneously with an extremely long cycle life.

Characteristics of ULTIMO

  • High Energy Density
  • High Operation Voltage
  • High Power
  • Instantaneous Charge and Discharge
  • Long Energy Preservation (Low Self Discharge Rate)

    • Item Standard Type Low Resistance Type Condition
