Abstract
A lithium cell (cell) suitable for use in a battery pack comprises a housing, first and second electrodes of opposite charge disposed and spaced from each other in the housing. The first electrode comprises a first active component and the second electrode comprises a second active component different from the first active component. The cell further comprises first and second current collectors disposed and spaced from each other in the housing. The first and second current collectors are in electrical communication with the first and second electrodes, respectively. The cell further comprises a separator disposed in the housing between the first and second electrodes.

A lithium cell suitable for use in a battery pack, said lithium cell comprising:
- a housing;
- a first electrode disposed in said housing and comprising a first active component;
- a second electrode disposed in said housing spaced from said first electrode and having an opposite charge from said first electrode and comprising a second active component different from said first active component;
- a first current collector disposed in said housing and in electrical communication with said first electrode;
- a second current collector disposed in said housing spaced from said first current collector and in electrical communication with said second electrode;
- a separator disposed in said housing between said first and second electrodes;
- and
- an additive of at least one of said first and second electrodes for maintaining a potential of said lithium cell in a range of from about 0.5V to about 1.5V and for preventing the potential from dropping below about 0.5V.
A lithium cell suitable for use in a battery pack, said lithium cell comprising:
- a housing;
