| Introducing JM Energy Lithium Ion Capacitor, ULTIMO |
|
“ULTIMO” stands for JM Energy’s virtue to provide “ultimate” performance and solutions for global environmental and energy preservation.
ULTIMO has higher energy density and higher voltage than conventional capacitors such as electric double layer capacitors (EDLCs). This enables ULTIMO to store larger amounts of electricity in smaller cells. Thus ULTIMOs are used in various applications under a wide range of operational conditions. |

| Industrial |
| Lithium Ion Capacitor based energy storage and peak power solutions are key for many industrial applications, where they store, bridge, deliver, ensure and smooth power and energy needs. They bridge power in uninterruptible back-up power and telecom network systems and assure 24 hour a day, 365 days a year power availability for wind turbine systems. LICs also ensure peak shaving and graceful power-down of robotic systems, improve primary energy sources for smooth energy throughput from renewable energy storage sources like solar applications, and efficiently enable high power pulse forming in power generators. |
| Consumer |
| In the consumer electronics market segment, Lithium Ion Capacitors can enhance the life of a conventional batteries as it absorbs and protects against any sags and surges in the voltage that could damage or limit the battery. Thus Lithium Ion Capacitors are ideal for a wide range of consumer electronic products. |
| Transportation |
| In the transportation segment, Lithium Ion Capacitors can play a very important role when an application requires an instantaneous charge and discharge. With its high power density, the uses in regenerative breaking as well as stop and go applications, are numerous. Breaking and accelerating consume high amounts of fuel and when Lithium Ion Capacitors are utilized, it can greatly improve fuel efficiency under stop-and-go driving conditions and successfully reduce overall fuel consumption of transportation systems. |
| Automotive |
| Lithium Ion Capacitors can store enough energy and deliver enough power to be useful in advanced automotive applications. With the demand for more luxuries in basic automobiles, Lithium Ion Capacitors’ power density and long life cycle, provide a complete solution to the increasing power needs found in the automotive industry. |
| Renewable Energy |
| Renewable energy sources such as wind, solar and water are quickly realizing the need for superior energy storage devices. Due to their high reliability, efficiency and operating lifetime, Lithium Ion Capacitors are ideal for renewable energy applications. Lithium Ion Capacitors are recognized as practically maintenance-free devices that do not require the costly test runs and expensive management systems of batteries. |
