Abstract
Electrical storage devices (10,38) are provided with pasted negative electrodes (12) and pasted positive electrodes (15) with porous separators (18) between them, with current collectors (20,22) disposed between the separator (18) and the negative and positive pastes (13,16), respectively.
Claims13
An electrical storage device comprising:
- a first electrode comprising a metal electrode that is pasted with a paste of electrochemically active material which is electrochemically negative;
- a second electrode comprising a metal electrode that is pasted with a paste of electrochemically active material which is electrochemically positive;
- and
- a porous separator disposed between the first electrode and the second electrode;
- wherein said electrical storage device further comprises:
- a first current collector in the form of a porous conductive layer disposed between the first electrode and the porous separator, said first current collector being in contact with the electrochemically negative paste of the first electrode;
- and
- a second current collector in the form of a porous conductive layer disposed between the second electrode and the porous separator, said second current collector being in contact with the electrochemically positive paste on the second electrode;
- wherein the first current collector and the second current collector are each in direct contact with the separator;
- the first electrode has a tab that is connectable to a primary negative terminal of the electrical storage device;
- the second electrode has a tab that is connectable to a primary positive terminal of the electrical storage device;
- the first current collector has a tab that is connectable to a secondary positive terminal of the electrical storage device;
- and
- the second current collector has a tab that is connectable to a secondary negative terminal of the electrical storage device.
