Abstract
A method for producing Li(Al) alloy anode comprises the steps of alloying Li and Al, grinding the formed alloy, pressing the powder around a current conductive thread and enclosing the anode element in a microporous separator material.
Claims1
Method for producing a Li(Al) anode for a lithium battery, in which Li and Al are pyrometallurgically alloyed in inert atmosphere and the formed alloy after cooling is ground to a homogenous powder, characterized in that the powder is pressed or extruded to form an elongated anode element (2) around a current conductive thread (1), which extends from at least one end of the anode element as a connector wire and in that the anode element is provided with an enclosure (3) of microporous separator material wherein a plurality of separate anode elements (2) at certain intervals on a current conductive thread (1) are formed in a continuous process, including the provision of the enclosures (3) of microporous separator material.
