A three-dimensional woven fabric for use in a battery is composed of three groups of filaments interlaced to form a three-dimensional weave, the filaments of one of the groups being formed of two kinds of electrode materials for a battery arranged parallely and alternately and the filaments of the other two groups serving as separators and being arranged so as to fix the filaments made of the electrode materials.

Three-dimensional woven fabric for battery

A method for the formation of a three-dimensional woven fabric comprises causing arms of carriers disposed around one component yarns out of three mutually perpendicular component yarns and having the other two component yarns separately held thereon to be rotated, opposing carrier arms of adjacent carriers to each other thereby effecting transfer of yarns, and successively effecting said transfer of yarns to carrier arms of the subsequent carriers thereby enabling the two component yarns to be displaced and zigzagged relative to the remaining one component yarn. An apparatus for effecting the aforementioned method essentially comprises a multiplicity of carriers arrayed longitudinally and laterally on a carrier holding plate and means for imparting necessary movements to the carriers. The three-dimensional woven fabric can be formed in a desired shape or yarn arrangement by suitably varying the pattern of arrangement of the two component yarns.

A three-dimensionally latticed flexible-structure composite, including a three-dimensional lattice formed of longitudinal, lateral and vertical strings and a matrix formed by selectively impregnating the component strings of the aforementioned lattice with a molten plastic, the precursor of the matrix, and allowing the molten plastic adhering to the strings to solidify.
