Abstract:
A battery comprising a battery case comprising an end face and a peripheral surface having an edge proximate to said end face defining a gap between said end face and said peripheral portion; a visible-light or near-infrared-light cured resin substantially filing said gap; a positive electrode; and a negative electrode; wherein both electrodes are operatively mounted within the case;wherein said resin composition comprises:a) a compound comprising at least one free radical polymerizable, ethylenic unsaturated, group; andb) a light curing catalyst having an absorption band in a visible-light or near-infrared-light wavelength region, which catalyst is selected to produce a radical on exposure to said visible light or near-infrared light,wherein said catalyst comprises at least one member selected from the group consisting of:1) a combination of a boron compound, a cationic dye, and an azo compound;2) a combination of a boron compound, a cationic dye, and an organic peroxide;3) a combination of a camphor quinone and an azo compound;4) a combination of a camphor quinone and an organic peroxide;5) a combination of a acyl phosphine oxide and an organic peroxide; and6) a combination of a acyl phosphine oxide and an azo compound.
