  • Porous structure Si Cu composite electrode of lithium ion battery and preparation method thereof
    Patent number: 11063264
    Abstract: The present disclosure discloses a porous structure Si/Cu composite electrode of a lithium ion battery and a preparation method thereof. The composite electrode comprises an active substance, a bulk porous Cu and a current collector, wherein the active substance Si is embedded into the bulk porous Cu, and the bulk porous Cu is in metallurgical bonding with the current collector and plays a dual role of “binder” and “conductive agent”, which not only relieves the pulverization and the shedding of the active substance Si particles but also improves electron transmission efficiency; and meanwhile, the porous structure increases the contact area between the active substance Si and electrolyte and increases the reaction efficiency of lithium insertion combination.
    Type: Grant
