The present disclosure relates to a welding device and a processing apparatus for a secondary battery current collector. The welding device includes: a welding head; and an anvil block. A welding station is disposed between the welding head and the anvil block. The welding device is configured to weld a foil to a portion of a composite current collector at the welding station. According to this solution, the foil can be used as a tab of the composite current collector by using the foil to connect with the composite current collector so as to output the current in the battery cell.

Welding device and processing apparatus for secondary battery current collector

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.

Current collector production apparatus

The disclosure relates to a baking apparatus for secondary battery. The baking apparatus for secondary battery comprises: a feeding device, a discharging device spaced from the feeding device in a horizontal direction, a baking device disposed between the feeding device and the discharging device, and a transferring device. The baking device comprises a baking oven including a housing and a cover for connecting hermetically with the housing. The transferring device is configured to put a secondary battery to be baked, which is conveyed by the feeding device, into the baking oven, and take the baked secondary battery out of the baking oven and convey it to the discharging device.

Baking apparatus for secondary battery

The present disclosure relates to a clamping apparatus and a transport device. The clamping apparatus comprises: a base; a support plate, stacked with the base in a vertical direction; a locking assembly, by which the support plate is connected to the base, wherein the locking assembly comprises a first locking member disposed on the support plate and a second locking member disposed on the base, the support plate is movable in the vertical direction and is capable of being connected to or separated from the base by connection or separation of the first locking member to or from the second locking member, and a horizontal load is able to be transmitted between the support plate and the base via the locking assembly; and a clamping assembly disposed on a surface of the support plate facing away from the base.
