Non-aqueous lithium battery

A method of making an anode-cathode assembly for a solid non-aqueous liquid electrolyte alkali metal cell for delivering high current pulses comprising the steps of:

• (a) providing an elongated ribbon-like anode conductor element;
• (b) providing a pair of elongated ribbon-like alkali metal elements;
• (c) pressing said alkali metal elements against said conductor element to form an elongated ribbon-like anode structure;
• (d) encapsulating said anode structure with separator material;
• (d) folding said anode structure at spaced intervals along the length thereof to form a serpentine structure;
• (f) providing a plurality of separate cathode elements;
• and
• (g) placing said plurality of cathode elements between corresponding ones of the folds of said serpentine anode structure.
