TAIYO YUDEN Adds an Item to Their Lithium Ion Capacitor LITHOSION™ Series

Featuring both long life and high volumetric energy density, contributing to greater reliability and miniaturization

TOKYO, September 19, 2018—TAIYO YUDEN CO., LTD. announced today the addition of

LIC1030RS3R8206 (φ10 mm × 30 mm, nominal capacitance 20 F) to our lithium ion capacitor

LITHOSION™*1 RS Series as the smallest product in volume. Example applications for this new

capacitor are peak assistance and backup power supply in servers, smart meters, and drive recorders.

Our lithium ion capacitor LITHOSION™ has a high operating temperature limit of 85°C (at 2.5 to

3.5 V) and a very long life compared to lithium ion rechargeable batteries. In addition, this capacitor also has

a high rated voltage of 3.8 V maximum (when the maximum operating temperature is 70°C) and achieves a

volumetric energy density more than twice as large as that of electric double layer capacitors. This allows

for an increase in the capacitance at the same volume, contributing to miniaturization of devices.

Production of this product will commence at TAIYO YUDEN’s subsidiary company, TAIYO

YUDEN ENERGY DEVICE CO., LTD. (Maebashi, Gunma prefecture, Japan), in September 2018. The

sample price is 800 yen per unit.

Technology Background

Servers and drive recorders require an emergency power supply as backup for data protection in the event of

an emergency, such as a power failure and accident. On the other hand, smart meters, which require a large

amount of energy within a short period of time for wireless data transmission, are equipped with a power

storage device for peak assistance as a measure to supplement their power supply. There has been a great

need for the miniaturization of those power supplies for backup or peak assistance. One way to achieve this

is to use long-life devices with a high energy density.

In response to such demand from the market, TAIYO YUDEN added LIC1030RS3R8206, the

smallest product in volume, to our lithium ion capacitor LITHOSION™ RS Series. It has achieved a higher

volumetric energy density than that of electric double layer capacitors. With this commercialization, the

lithium ion capacitor LITHOSION™ product lineup has been expanded to four items, which allows us to

offer a variety of products with different sizes and capacitances in accordance with the devices or

applications of our customers.

We will continue to develop our lineup of lithium ion capacitor LITHOSION™ products in response

to demand from the market.
