　　Development of 18650 lithium-ion battery capacitors (1): high voltage, large capacity, high safety

　　FDK has developed 18650 lithium-ion battery capacitors with high output power and excellent charge and discharge cycle characteristics. It is now being used in fields such as high-voltage sag compensation devices and load averaging for solar power generation. In addition, its application in automotive fields that require high output, such as hybrid vehicles, is also progressing. In this article, FDK introduces the characteristics of 18650 lithium-ion battery capacitors and its initiatives for hybrid vehicles, etc.

　　In recent years, various countermeasures have been taken to cope with the depletion of fossil fuels and prevent global warming. In response to the problem of fossil fuels, natural energy sources such as solar power generation and wind power generation have been actively introduced. In order to prevent global warming, we have begun to implement emission reduction measures such as electrification and motor-assisted driving for vehicles with high CO2 emissions.

　　However, these countermeasures have led to the emergence of new issues such as unstable power systems and increased power consumption. To solve these problems, power storage components are indispensable.

　　Previously, the development of power storage components has been centered on 18650 lithium-ion battery rechargeable batteries (LIB). However, due to different uses, LIB's output characteristics and charge-discharge cycle life (hereinafter referred to as life) have limits. We have developed EneCapTen, a high-output and long-life 18650 lithium-ion battery capacitor (LIC) for applications that are difficult to support with LIB. This article will introduce LIC’s application solutions for the hybrid vehicle market, a market expected to grow in the future.
