MANUFACTURING METHOD OF ELECTRODE BAND FOR ELECTROCHEMICAL CURRENT SOURCE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC H01M4/26 H01M4/20 H01G9/04 

FIELD: electricity.

SUBSTANCE: in manufacturing method of electrode band for electrochemical current source at application of active mass from bunker to band the mass is subject to vibration and at the same time impact actions are performed on the applied layer of active mass on the band. Impact actions are performed within 0.3-4.5 of vibroimpact per 1 mm of movement of band and with amplitude of vibrations of 0.2-2.5 mm with frequency of 10-200 Hz. Then, surface sealing is performed by smoothing active mass and excess mass is removed. Device for manufacturing electrode band for electrochemical current source includes vertical bunker having in its lower part an outlet opening, pasting table located under bunker, band broaching mechanism and oscillator of high-frequency oscillations, which is arranged in bunker, and vibrator; end of wall of bunker outlet portion on the side of band outlet is located relative to surface of broaching table with a gap and equipped with adjustable gauging plank. The rest three side walls of outlet bunker portion are equipped with restricting planks installed on lower edges of walls with possibility of vertical movement along them. Planks are spring-loaded to the table with possibility of band pressure crosswise and along its longitudinal edges. Oscillator is made in the form of a plate with through holes and equipped with vertical guides for alignment relative to bunker walls. Working end of oscillator is equipped with shock absorber from elastic polymer material and protrudes above edge of lower bunker portion and is located on the level of lower edges of restricting planks which are in spring-loaded state.

EFFECT: higher strength of obtained electrodes owing to good adhesion of active mass to band and qualitative sealing of active mass.
