Lead dioxide electrode and preparing method thereof

Abstract

The invention belongs to electrochemistry technology field, relates to a lead dioxide electric pole and preparation method thereof. The electric pole is made of lead dioxide powder and poly-4-oxyethylene or polypropylene particles in a certain mass ratio by mixing and pressing them. The invention is a no-basal body preparation method, solves the problem of coating pull-off radically. The electric pole has advantages of high mechanical strength, high corrosion resistance, high electrochemical activity and simple preparation technique.

Description

technical field

[0001] The invention belongs to the technical field of electrochemistry, and in particular relates to a lead dioxide electrode and a preparation method thereof. Background technique

[0002] PbO 2 As a kind of insoluble anode material with good performance and low price, the electrode has not only been used in the chemical industry, but also has a good application prospect in the field of environmental protection.

[0003] PbO 2 Electrodes can be divided into two types: matrix electrodes and matrix-free electrodes. Conventional matrix-free PbO 2 Electrodes are not suitable for industrial applications due to their poor mechanical strength. The current application is generally the matrix PbO 2 Electrodes, among which titanium-based PbO is more researched 2 electrode. Titanium is a valve-type metal, and it is a good carrier for many electrocatalytic active materials. A layer of conductive and corrosion-resistant PbO is plated on the titanium base. 2 Fina...
