New Trends of Powder Process Contributing to Electric Double Layer Capacitor Technology

Abstract

In latest years， from the viewpoint of promotion of use of the oil alternative energy and the prevention of global warming measures with the CO₂, the need of the electric car or the low-emissions vehicles such as hybrid cars is strongly demanded and the new use development of the electric double layer capacitor with the superior characteristic which the batteries do not have, is accelerating it. The improvement of performance of the active carbon which is electrode materials is advanced by the high capacity of electric double layer capacitor.

It goes without saying that it is necessary to improve the characteristic of capacitor and the reliability by the improvement of the cell structure. We connected it in series, which has become indispensable to abtain the high efficiency of the whole system including the neighboring circuit’s high reliability.

We introduce the latest trend of the recent capacitor market situation and the related powder processes and technology.
