Abstract
An electrochemical cell having an electrode stack arranged in a zigzag configuration. Additional electrodes may be inserted within the folds of the zigzag configuration. Preferably, the electrochemical cell is a prismatic cell.
Claims46
An electrochemical cell, comprising:
- at least one positive electrode;
- at least one negative electrode;
- and
- an electrolyte,
- wherein said at least one positive electrode and/or said at least one negative electrode folded in a zigzag configuration.
2 more elements
An electrochemical cell, comprising:
- an electrode stack including a positive electrode and a negative electrode, said electrode stack folded in a zigzag configuration having folds and creases;
- and
- an electrolyte.
An electrochemical cell, comprising:
- an electrode folded in a zigzag configuration having folds and creases;
- at least one counter-electrode disposed within one or more of the folds of said electrode;
- and
- an electrolyte.
1 more element
An electrochemical cell, comprising:
- an electrode folded in a zigzag configuration having folds and creases;
- and
- at least one bifold counter-electrode having a first leg and a second leg, said first leg and said second leg disposed within a first and a second fold on the same side of the zigzag configuration of said electrode.
An electrochemical cell, comprising:
- a bifold negative electrode having a first and a second leg;
- a bifold positive electrode having a first and a second leg;
- and
- an electrolyte,
- wherein the first leg of said negative electrode is disposed between the first and second leg of said positive electrode, and the first leg of said positive electrode is disposed between the first and second leg of said negative electrode.
2 more elements
An electrochemical cell, comprising:
- an electrode stack including an electrode disposed between a first and a second counter-electrode, said electrode stack folded in a zigzag configuration with folds and creases;
- and
- an electrolyte.
