Abstract: The present disclosure relates to a current collector production apparatus for producing a current collector. The current collector includes a current collector substrate, a conductive layer disposed on at least one surface of the current collector substrate. The current collector production apparatus includes an oven having a space where the current collector is to be heated, and a passivation ozone knife having a current collector injection port. The current collector injection port is configured to release ozone in such a manner that the ozone reacts with a surface material of the conductive layer, so as to form a passivation layer. The passivation ozone knife is disposed inside the oven. The current collector produced in the present disclosure can prevent HF in electrolyte from reacting with Al, so as to solve a problem of detachment of active material from the current collector and maintain the performance of lithium-ion battery.
