ABSTRACT:
A photocurable tubular electrode (10) and means (30) for fabricating same is disclosed. In one embodiment, a glass braid (66), saturated with a photocurable resin, is partially cured in the presence of visible light. The still flexible braid (66) is then shaped into a sheath (28) and fully photocured. The now rigid sheath (28) is disposed about spaced spines (14) comprising the tubular electrode (10) to form tubes (18) whereupon active material (20) is introduced into the tubes (18). In an alternative embodiment, the partial curing step is eliminated. The resulting sheath (28) displays superior battery performance while simultaneously reducing pollution effluents and energy requirements.
