A new technique for securing into place a plurality of layers which make a battery body, and for preventing electrical short-circuits within the battery by retarding the formation of dendritic growths is disclosed. A radiation curable layer of material is coated onto a portion of at least one outwardly exposed face of a battery body, whereupon the layer of material is then cured. The cured layer of material is positioned relative to the body such that the cured layer provides support to the body in a manner to secure in place a plurality of layers which make up the battery body, thereby ensuring proper electrical contact between the plurality of layers. In addition, the cured layer of material is also positioned such that the cured layer inhibits formation of short circuiting electrical paths between the anode and cathode layers of the battery, the paths being caused by formation of dendritic growths extending out from the anode layer towards the cathode layer. |

DETAILED DESCRIPTION These and additional objectives are accomplished by the various aspects of the present invention, wherein, briefly, according to a principal aspect, a radiation curable layer of material is coated onto a portion of at least one outwardly exposed face of a battery body, whereupon the layer of material is then cured.
The cured layer of material is positioned relative to the body such that the cured layer provides support to the body in a manner to secure in place a plurality of layers (e.
g.
anode, cathode, electrolyte, current collector, etc.
) which make up the body, thereby ensuring proper electrical contact between the plurality of layers.
In addition, the cured layer of material is also positioned such that the cured layer inhibits formation of short circuiting electrical paths between the anode and cathode layers of the battery, the paths being caused by formation of dendritic growths extending out from the anode layer towards the cathode layer.
Thus, in accordance with this principal aspect, the present invention functions as both (1) a battery frame for securing into place the plurality of layers which make the battery body, and/or (2) a barrier layer for preventing electrical short-circuits within the battery by retarding the formation of dendritic growths.
These two different aspects of the present invention will, herein, each be discussed in greater detail separately.
A first main aspect of the present invention is directed to a new technique for securing into place the various layers of a flat cell battery, wherein at least a portion of a body of the flat cell battery is encased in a radiation cured frame such that the frame provides support to the body in a manner to secure in place a plurality of layers in the body, thereby insuring good electrical contact between the various layers of the cell.
Related to this first main aspect, another aspect of the invention is directed to a method for making a radiation curable frame for a stackable cell battery comprising the steps of applying a radiation curable material onto at least a portion of the battery body, and curing the material to thereby form a cured frame which encases at least a portion of the cell body and provides support to the cell body in a manner to secure in place the various stacked layers in the body
