Double-sided electrodeposition equipment, double-sided electrodeposition method and produced product

Abstract

The invention discloses a double-sided electrodeposition equipment, a double-sided electrodeposition method and a prepared product. The double-sided electrodeposition equipment includes a front titanium basket and a rear titanium basket. The double-side electrodeposition equipment also includes: electrically connected to the front titanium basket. The first rectifier of the basket is electrically connected to the second rectifier of the rear titanium basket; wherein, the first rectifier is configured to distribute current to the front titanium basket, and the second rectifier is configured to distribute current to the rear titanium basket, and according to a predetermined current distribution Compared with at least two electrodepositions on the product to be electrodeposited, the double-sided electrodeposition equipment according to the embodiment of the present invention controls the current distribution of the front titanium basket and the rear titanium basket by setting the first rectifier and the second rectifier, and according to the predetermined current Distribution ratio Electrodeposition of the product to be electrodeposited at least twice can weaken the unevenness of nickel plating on the inner side of nickel foam and improve the overall nickel plating effect, thereby increasing the deposition thickness and improving the compression resistance of foam nickel and the volume winding performance.

Description

technical field [0001] The invention relates to the field of processing technology, in particular to a double-sided electrodeposition equipment, a double-sided electrodeposition method and a prepared product. Background technique [0002] When manufacturing nickel foam, in the early stage of traditional symmetrical electroplating, the resistance of the foam plastic matrix is ​​relatively high, and the current distribution is mainly concentrated on the collector end. At this time, the amount of nickel plating on the collector side (outside of the foam plastic) is high; (The outer side of the foamed plastic) has a small resistance and is close to the solution phase. If the liquid phase polarization is not considered, the current is mainly concentrated on the outer side. Therefore, the amount of nickel plating on the outer side of the foamed nickel is large, and the middle is less, resulting in foamed nickel. The symmetrical distribution of the amount of nickel plating inside a...

[0002] When manufacturing nickel foam, in the early stage of traditional symmetrical electroplating, the resistance of the foam plastic matrix is ​​relatively high, and the current distribution is mainly concentrated on the collector end. At this time, the amount of nickel plating on the collector side (outside of the foam plastic) is high; (The outer side of the foamed plastic) has a small resistance and is close to the solution phase. If the liquid phase polarization is not considered, the current is mainly concentrated on the outer side. Therefore, the amount of nickel plating on the outer side of the foamed nickel is large, and the middle is less, resulting in foamed nickel. The symmetrical distribution of nickel plating inside and outside, this symmetrical distribution cannot be weakened by secondary electroplating

As a result, the coating thickness of the nickel foam middle layer is small, resulting in a relatively small deposition thickness, and the compression resistance and winding performance of the foam nickel are poor
