Flat battery

Claim 2

A planar battery comprising: at least two discrete, sheet-type electrically conductive electrode supports substantially permeable to volatile effluvia generated internally of said battery; separator means, electrode active material and electrolyte configured and arranged between said electrode supports to define at least one cell within said battery; means defining a seal about the peripheral portion of said cell, said seal being formed inwardly of peripheries of said electrode supports to expose a portion thereof to the external environment of said battery in which said means defining said seal includes an electrically insulative frame having an opening defined by an inner border, an outer periphery and surface sealing portions intermediate said inner border and outer periphery, and in which said electrically insulative frame outer periphery extends outwardly beyond the periphery of said electrode supports.

Claim 3

The planar battery of claim 1 in which; said conductive electrode supports are formed of carbon impregnated polyvinyl chloride sheet; and said insulative frame is heat sealed thereto only along said surface sealing portions.

Claim 4

The planar battery of claim 1 in which said separator means is formed of electrolyte permeable sheet material configured having a periphery extending over said frame inner opening and remaining inwardly of said surface sealing portions.

Claim 5

The planar battery of claim 3 in which said separator means is bonded to said frame along a surface thereof situate between said inner border and said sealing portions.

Claim 6

The planar battery of claim 3 in which said electrode active material includes zinc anode material, and manganese dioxide and carbon cathode material.

Claim 7

The planar battery of claim 3 in which said electrode supports and said frames are formed of materials mutually compatible to effecting a thermally induced bond therebetween.

Claim 8

In a planar battery of a variety including carbon impregnated polymeric sheet electrode supports, sheet separator means, electrode active materials and electrolyte adjacent over said electrode supports, said electrode active materials being mutually separated in electrically insulative fashion by said sheet separator means, and a peripherally disposed seal component; the improvement wherein said seal is formed in attachment with mutually spaced ones of said electrode supports inwardly of the peripheries thereof so as to permit venting to the atmosphere of cells of said battery, wherein said seal includes an electrically insulated frame having an opening defined by an inner border, and an outer periphery; said attachment being effected at surface regions thereof intermediate said inner border and outer periphery, and in which said electrically insulative frame outer periphery extends outwardly beyond the periphery of said electrode supports.

Claim 9

In a planar battery of a variety including carbon impregnated polymeric sheet electrode supports, sheet separator means, electrode active materials and electrolyte adjacent over said electrode supports, said electrode active materials being mutually separated in electrically insulative fashion by said sheet separator means, and a peripherally disposed seal component; the improvement wherein said seal is formed in attachment with mutually spaced ones of said electrode supports inwardly of the peripheries thereof so as to permit venting to the atmosphere of cells of said battery, wherein said seal includes an electrically insulated frame having an opening defined by an inner border, and an outer periphery; said attachment being effected at surface regions thereof intermediate said inner border and outer periphery, and in which said electrically insulative frame outer periphery extends outwardly beyond the periphery of said electrode supports.

Claim 10

The planar battery of claim 7 wherein said frame is formed of polyvinyl chloride.

Claim 11

The planar battery of claim 7 in which said separator means is formed of electrolyte permeable sheet material configured having a periphery extending over said frame inner opening and remaining inwardly of said surface sealing portions.

Claim 12

The planar battery of claim 8 wherein said sheet electrode supports are formed of carbon impregnated polyvinyl chloride.

Claim 13

The planar battery of claim 9 in which said separator means is bonded to said frame along a surface thereof situate between said inner border and said sealing portions.

Claim 14

The planar battery of claim 9 in which said electrode active material includes zinc anode material, and manganese dioxide and carbon cathode material.

Claim 15

The planar battery of claim 9 in which said electrode supports and said frames are formed of materials mutually compatible to effecting a thermally induced bond therebetween.
