Lithium-ion capacitors have a wide range of applications, because it combines the advantages of lithium batteries and traditional double-layer capacitors, compared with lithium batteries, it is more stable, very few self-discharge; compared with the electric double layer capacitors, both Of the charging speed is not much difference, but the energy density is higher than the electric double layer capacitor, in the case of the same amount of electricity, the size is only a fraction of the latter.

At present, in the electric double layer capacitor on the basis of improved lithium-ion capacitors used in four areas: 1, balance wind power, when the breeze when the power generation is small, available power supply; strong winds can use the capacitor storage, 2, street lamp battery, a fully charged unit (including LED lights, solar panels, lithium-ion capacitors) can be maintained overnight lighting, if the use of nickel-metal hydride batteries or lithium-ion battery is necessary to design complex control module; Electricity balance, and the principle of the same wind power, lithium-ion capacitors in the UPS uninterruptible power supply systems, engineering elevators and other applications in the auxiliary peak current, so that the main power supply through the small capacity of the system to achieve miniaturization; 4, standby power: Powered cars and small electronic control equipment applications.

Lithium-ion capacitors with its miniaturization advantage in the added value of a certain attraction, while its re-use characteristics of good, reducing the replacement and maintenance of the trouble. As a high-end power supply, its development has shown good prospects.

1, to replace the electric double layer capacitor and some special purpose lithium battery, but its replacement speed is not fast, which is determined by the price.

2, the scope of application to expand.

3, sub-national industrialization point of view, Japan will continue to lead, while China is lagging behind.

4, mass production technology breakthroughs, in particular, is a breakthrough in new materials technology, here may learn from the current lithium battery technology improvements, especially power lithium battery technology improvements, because the power lithium battery safety and consistency requirements on the comparison High, this technological progress is bound to lithium-ion capacitor technology has a significant role in promoting.
