Embodiment Construction

[0027] The present invention will be further described below in conjunction with drawings and embodiments.

[0028] Such as figure 1 , Figure 2 and image 3 A metal foil strip electroplating system shown includes an unwinder 1, a plating head elevator 2, a plating head 3, an electroplating tank 4, a washing box 5, a blast drying oven 6 and a winder 7, and the metal foil strip 8. One end is connected to the unwinding machine 1, and the other end is connected to the winding machine 7. In the direction in which the metal foil strip 8 advances, an electroplating tank 4, a washing box 5, and a blast drying box 6 are arranged in sequence, and a plating head lifter 2 The plating head 3 is connected, and the plating head 3 is arranged above the electroplating tank 4 . Plating head elevator 2 is provided with the manual handle 20 that regulates plating head 3 heights. The winder 7 is connected to a force induction motor 11. When the metal foil strip 8 is stretched, it is controlled ...

Abstract

The invention discloses a metal foil belt material electroplating system, which comprises an unreeling machine, a plated head lifter, a plated head, an electroplating bath, a washing box, a blasting drying box and a wrapup machine, wherein, one end of a metal foil belt material is connected with the unreeling machine and the other end of the metal foil belt material is connected with the wrapup machine; the electroplating bath, the washing box and the blasting drying box are arranged on the forward direction of the metal foil belt material in turn; and the plated head lifter is connected with the plated head which is arranged above the electroplating bath. The metal foil belt material electroplating system is applied to continuous preparation of novel alloy cathode materials of a lithium ion battery and can perform double-sided electroplating on various metal foil belt materials. The metal foil belt material electroplating system performs continuous integrated processing of electroplating, washing and drying on the metal foil belt materials, thereby the efficiency is high and the operation is convenient. Moreover, the metal foil belt material electroplating system has the advantages of low cost, small pollution, capability of performing double-sided coating, tight cladding which is difficult to fall off, controllable thickness and particle diameter and so on.

Description

technical field [0001] The invention relates to the processing of metal foil strips, in particular to a metal foil strip electroplating system and its application. Background technique [0002] Lithium-ion secondary batteries have become an important energy source for portable devices. Carbon material is the anode material of commercialized lithium-ion batteries at present, and its theoretical capacity is 372mAh·g -1 , It has been difficult to meet the miniaturization development of various electronic equipment and the extensive demand of electric vehicles for large-capacity and high-power chemical power sources. Therefore, research on new alloy anodes that can replace existing carbon anodes is becoming more and more active. [0003] Lithium can reversibly form alloys with most metals (Si, Sn, Sb, Al, etc.). These metals can be used as anode materials for lithium-ion batteries. The processing performance and capacity density of the alloy negative electrode material are b...
