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.
Claims18
Electrode assembly, comprising:
- a fan-folded multilayer containing
- a separator as an inner layer,
- continuous lengths of 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 directly attached to the upward folds of the fan-folded multilayer, and
- a second terminal that is directly attached to the downward folds of the fan-folded multilayer,
- wherein the first terminal consists of a rectangular plate that completely covers the upwards folds, and
- wherein the second terminal consists of a rectangular plate that completely covers the downward folds.

Method for producing a fan-folded electrode assembly comprising:
- applying an electrode material on a first and on a second side of a separator, applying an electrolytic liquid on the coated separator,
- joining continuous lengths of current collectors with the obtained separator so that the current collectors form outer layers,
- folding the obtained multilayer electrode assembly into a fan-fold configuration, and
- directly attaching a first terminal to upward folds and a second terminal to downward folds,
- wherein the first terminal consists of a rectangular plate that completely covers the upwards folds, and
- wherein the second terminal consists of a rectangular plate that completely covers the downward folds.
