METHOD FOR MANUFACTURE OF NEGATIVE ELECTRODE FOR LITHIUM CURRENT/SOURCE Russian patent published in 2000 - IPC

FIELD: chemical current sources, applicable in production both of primary and secondary current sources with a lithium electrode. SUBSTANCE: the method for manufacture of negative electrode for a lithium current source by pressing of electrode active material on a metal screen of the current tap consists in the fact that prior to pressing a needle perforation is made on the surface of the current tap metal screen, whose burrs are directed towards active material; the relations between the area of the perforation ports and the area of the current tap (opening percentage) are selected within 30 to 60%, the area of the perforation port is taken to be larger than the area of the screen cell, the maximum height of the burrs should not exceed the thickness of the pressed active material. EFFECT: simplified process of manufacture.
