[0014] The present invention also provides a method for manufacturing an electroformed nickel mesh for lithium battery electrodes, comprising the following steps:

[0015] S1: Place the casting and the nickel column in a reaction tank, put the electrolyte in the reaction tank, start the power supply, and the circuit begins to conduct. The positive ions in the electrolyte are reduced to atoms at the cathode and accumulate on the surface of the casting. The nickel column on the nickel column is decomposed, and the nickel metal ions in the nickel column will become metal ions due to the loss of electrons, and are continuously added to the electrolyte to keep the concentration of the electrolyte basically unchanged.

[0016] S2: When the power is turned on, the driving motor runs, the turntable follows the driving motor, the connecting column follows the turntable, and the connecting plate moves back and forth. The connecting rod pulls the shaking support assembly back and forth to accelerate the decomposition of the nickel column.

[0017] S3: When the nickel column is about to be consumed, the spare nickel of the spare component will squeeze the two hinged plates under the spring restoring force, causing the two hinged plates to flip downward, and the spare component moves downward, pushing the first sliding body to slide downward, so that the nickel column that is almost completely consumed and the first sliding body pass through the passage groove and enter under the bottom plate.

[0019] The present invention sets a shaking support component, starts the power supply, and the circuit begins to conduct. The positive ions in the electrolyte are reduced to atoms at the cathode and accumulated on the surface of the cast body. The nickel column on the nickel column part is decomposed, and the nickel metal ions in the nickel column will become metal ions due to the loss of electrons, and are continuously added to the electrolyte, so that the concentration of the electrolyte remains basically unchanged. At the same time, when the power supply is started, the driving motor runs, the turntable follows the driving motor to run, and the connecting column follows the turntable to run so that the connecting plate moves back and forth left and right. The connecting rod pulls the shaking support component back and forth to make the nickel column part contact with the electrolyte more fully, accelerate the decomposition of the nickel column, and shorten the time for making the electroformed nickel mesh. The two sliding parts can accelerate the shaking frequency of the connecting column, decompose the nickel column more quickly, and shorten the time for making the electroformed nickel mesh. The two push rods can ensure the parallel movement of the two push plates of the shaking support part to prevent the two push plates from tilting and causing the electrolyte to overflow. By setting spare nickel, when the nickel column is about to be consumed, the spare nickel of the spare assembly will squeeze the two hinge plates under the spring restoring force, so that the two hinge plates flip downward, the spare assembly moves downward, and pushes the first sliding body to slide downward, so that the nickel column that is almost completely consumed and the first sliding body pass through the passage groove and enter the bottom of the bottom plate, the second sliding body is inserted into the sliding groove. One end is connected with a conductive sheet, and the side wall of the support column is installed with a high-frequency conductor, and the high-frequency conductor is electrically connected to the drive motor. When the bottom of the spare assembly abuts against the top of the bottom plate, the conductive sheet and the high-frequency conductor are connected, so that the drive motor switches to high frequency, so that the speed point of the drive motor is faster, and the spare nickel is electrolyzed faster after the previous electroforming is completed so that the nickel column parts are more fully in contact with the electrolyte, the decomposition of the spare nickel is accelerated, and the time for making the electroformed nickel mesh is shortened. The structure of the present invention is ingenious, and it can be electroformed by decomposing two nickel columns without a large nickel column. By shaking during electroforming, the nickel column parts are more fully in contact with the electrolyte, the decomposition of the nickel column is accelerated, and the time for making the electroformed nickel mesh is shortened.

At the same time, when the power supply 21 is started, the driving motor 311 is operated, the rotating disk 312 follows the driving motor 311 to operate, and the connecting column 313 follows the rotating disk 312 to operate. The connecting plate 315 moves back and forth, and the connecting rod 32 pulls the shaking support assembly 34 to move back and forth, so that the nickel column 451 is in contact with the electrolyte more fully, which speeds up the decomposition of the nickel column 453 and shortens the time for making the electroformed nickel mesh. The two sliding parts 33 can speed up the shaking frequency of the connecting column 313, decompose the nickel column 453 more quickly, and shorten the time for making the electroformed nickel mesh. The two push rods 341 can ensure the parallel movement of the two push plates 343 of the shaking support 340 to prevent the two push plates 343 from tilting and causing the electrolyte to overflow. By setting up the spare nickel 52, when the nickel column 453 is about to be consumed, the spare nickel 52 of the spare component 50 will squeeze the two hinge plates 54 under the restoring force of the spring 51, so that the two hinge plates 54 flip downward, and the spare component 50 moves downward, pushing the first sliding body 455 to slide downward, so that the nickel column 453 that is almost completely consumed and the first sliding body 455 pass through the passage groove and enter under the bottom plate 459. The end of the second sliding body 55 inserted into the sliding groove 454 is connected with a conductive sheet, and the side wall of the support column 452 is installed with a high-frequency conductor, which is electrically connected to the drive motor 311. When the bottom of the spare component 50 abuts against the top of the bottom plate 459, the conductive sheet is connected to the high-frequency conductor, so that the drive motor 311 switches to high frequency, so that the speed point of the drive motor 311 is faster, and the spare nickel 52 is electrolyzed faster after the early electroforming is completed so that the nickel column 451 is in more full contact with the electrolyte, thereby accelerating the decomposition of the spare nickel 52 and shortening the time for making the electroformed nickel mesh. The present invention has an ingenious structure and can perform electroforming by decomposing two nickel pillars 453 without a large nickel pillar 453. By shaking during electroforming, the nickel pillar 451 is more fully in contact with the electrolyte, which accelerates the decomposition of the nickel pillar 453 and shortens the time for making the electroformed nickel mesh.

[0051] The present invention also provides an electroformed nickel mesh for lithium battery electrodes, comprising an electroformed nickel mesh and a mesh protective shell, wherein the mesh protective shell is sleeved on the periphery of the electroformed nickel mesh, and a pattern groove is provided on the top of the electroformed nickel mesh. In the electroformed nickel mesh for lithium battery electrodes, a specific pattern is usually printed on the surface of the substrate, and the mesh protective shell can prevent the electroformed nickel mesh from being shaken during transportation and colliding with other components, thereby affecting subsequent use.

[0052] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-mentioned embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
