Abstract
Provided is a process for producing a rope-shape alkali metal-sulfur battery, comprising (a) providing a first electrode comprising a conductive porous rod and a mixture of a first electrode active material and a first electrolyte residing in pores of the first porous rod; (b) providing a porous separator wrapping around the first electrode to form a separator-protected first electrode; (c) providing a second electrode comprising a conductive porous rod having a mixture of a second electrode active material and a second electrolyte residing in pores of the second porous rod; (d) combining the separator-protected first electrode and the second electrode to form a braid or a yarn; and (d) encasing the braid or yarn with a protective sheath; wherein one of the electrodes is a cathode containing sulfur or a sulfur compound as a cathode active material and the battery has a length-to-diameter aspect ratio no less than 5.
