Disclosed is a battery cell comprising a positive plate, a negative plate, and an electrolyte in contact with both plates, at least one of the plates comprising a rigid reticulated metal structure comprised of an electrically conductive metal formed of rigid elongated tendrils which have a dimension of thickness and length and a surface area, the tendrils being continuously joined to one another at apexes of three tendrils to form a rigid structure containing a plurality of pentagonally- faced dodecahedrons, the dodecahedrons being joined to one another, all to form the unitary structure, the plate having a pair of parallel, spaced apart faces bounded by edges to define a plate envelope having a volume. The dimensions and number of the tendrils is selected to provide interconnected open pores inside the structure having a volume open to flow between the faces, providing a reservoir for electrolyte to be stored and to contact the tendrils.
L'invention concerne une structure de batterie électrochimique qui comprend deux plaques conductrices (électrodes) (30, 34) qui présentent des charges opposées pendant le chargement et le déchargement de la batterie. Chaque plate (ou substrat)(170) comprend un corps rigide composé de vrilles métalliques conductrices allongées (174) et reliées ensemble pour former un ensemble rigide. Ces vrilles forment une structure rigide et comportent des surfaces entre lesquelles des passages s'étendent dans toutes les directions dans la plaque d'une surface à l'autre de cette dernière.
