Abstract
A battery apparatus comprising a casing and at least one stacked lithium ion cell which does not require springs, windings, etc. and a member for precluding inadvertent deformation of the casing. Each of at least one stacked lithium ion cell is positioned within the casing. The deformation precluding member is associated with each of the at least one lithium ion cell, and, substantially precludes inadvertent deformation of the casing by the at least one lithium ion cell, during cell cycling and storage. The invention further includes a process for fabricating a battery apparatus.
Claims15
A battery apparatus comprising:
- a casing;
- at least one stacked lithium ion cell positioned within the casing;
- and
- means operatively associated with each of the at least one lithium ion cell for substantially precluding inadvertent deformation of the casing by the at least one lithium ion cell, during cell cycling and storage.
A process for fabricating a battery apparatus comprising the steps of:
- forming a casing for housing at least one stackable lithium ion cell;
- fabricating at least one lithium ion cell including the step of
- associating a chemical compound within the cell which will substantially preclude inadvertent deformation of the casing, after positioning of the cells therein, by the cell during cell cycling and storage;
- and
- positioning the at least one stackable lithium ion cell within the casing.
