Abstract
Provided is a process for producing a rope-shaped alkali metal battery, comprising: (a) providing a first electrode comprising a first conductive porous rod and a first mixture of a first electrode active material and a first electrolyte residing in the pores of the first porous rod; (b) wrapping or encasing a porous separator around the first electrode to form a separator-protected first electrode; (c) providing a second electrode comprising a second conductive porous rod and a second mixture of a second electrode active material and a second electrolyte residing in the pores of the second porous rod; (d) combining the separator-protected first electrode and second electrode to form a braid or a yarn having a twist or spiral electrode; and (e) wrapping or encasing a protective casing or sheath around the braid or yarn to form the rope battery.
