Abstract

An electrode assembly includes a fan-folded multilayer containing a separator as an inner layer, current collectors as outer layers, and electrode material between the two sides of the separator and the current collectors, and a first terminal that is attached to the upward folds of the fan-folded multilayer and a second terminal that is attached to the downward folds of the fan-folded multilayer. An energy storage device includes the electrode assembly.

Abstract

A very high capacity capacitor or energy storage comprising a two-layer electrode structure with a separator and an electrolytic fluid, where the electrodes are parallel and connected to one of two terminals. The electrodes are connected to the terminal along a large length so that the connection to the terminal has a low resistance and so that charging may take place faster and with less heat generation.
