METHOD OF CONTACT WELDING OF CURRENT COLLECTOR UNIT TO BASE OF FIBROUS ELECTRODE Russian patent published in 2013 - IPC H01M4/16 H01M10/30 

FIELD: electricity.

SUBSTANCE: method of contact welding of a current collector unit to a base of a fibrous electrode of an alkaline accumulator includes cutting of the base in compliance with the electrode stock, pre-pressing of a zone of additional deposition of nickel, with the area of 5.8-6.9%, relative to the total area of the stock, with the specific pressure of 21400 - 22300 kgf/cm² and welding of a contact plank with current of 130-160 A for 0.15-0.35 s.

EFFECT: increased service life and higher capacity characteristics of nickel-cadmium accumulators with fibrous electrodes by means of increasing quality of contact welding of a current collector unit is the technical result of the invention.
