  • Process for preparing cathode of lithium battery and lithium battery having the cathode
    Patent number: 11145854
    Abstract: A process for preparing a cathode of a lithium battery, having the following steps: (a) Longitudinally punching a metal band to form irregular filamentous holes, horizontally stretching the metal band, and performing compaction to give the metal net irregular filamentous holes; (b) After the metal net is cleaned and dried, processing the metal net surface by a laser less than 5W, of 500-1000W, and of 10-100W sequentially; and (c) Coating the metal net, having the surface processed with lasers, with a prepared cathode paste, and drying, pressing, and cutting the metal net to obtain a battery cathode.
