Nichicon Corporation has developed an ultra-slim electric double-layer capacitor (EDLC) with a target application in peripherals for tablets and mobile devices.

The product will be on display at CEATEC JAPAN 2015 from October 7 to 10 (Wed.-Sat.) at the Makuhari Messe in Chiba, Japan

Overview, Background of Development
With the rapid expansion of tablets and mobile devices, there has been a wide range of peripheral equipment developed that takes advantage of these products’ networks. This field is demanding increasingly smaller components that offer more advanced functions. It is also crucial that components use space effectively in order to fit into the shapes of this peripheral equipment.

Main Features
Nichicon’s previous cylindrical shaped EDLC measured φ6.3×9L mm and had the industry’s highest capacitance of 1F. The newly developed product is the first in the industry to achieve an ultra-slim φ4×30L mm. Despite its thinness, it still has a capacitance of 1F thanks to Nichicon technology for winding a high-capacity electrode into the capacitor’s long, thin shape.

This EDLC can also be made to order in a dimension of φ5×20L mm. The main applications for this new EDLC will be the stylus and other peripherals used with tablets and mobile devices. The EDLC’s ultra-thin shape allows it to fit into small spaces. It can also be used for backup power in, wearable technology. And with its ability to be charged on even very slight electrical currents, it holds promise for application in the field of energy harvesting.
