With the continuous development of the new energy market, the lithium battery industry has gradually become the focus of global attention. As an indispensable part of the lithium battery production process, the application of diaphragm filter press is also becoming more and more extensive. This article will introduce in detail the application and characteristics of diaphragm filter press in the lithium battery industry.
1. Overview of diaphragm filter press.
Diaphragm filter press is an advanced solid-liquid separation equipment, which is widely used in various industrial fields. Its working principle is to use a diaphragm to separate the adjacent filter plates to form an independent filter chamber, and to achieve solid-liquid separation through pressurized feeding. The diaphragm filter press has the advantages of fast filtration speed, good filtration effect and high degree of automation.
Second, the application of diaphragm filter press in the lithium battery industry.
1.Lithium-ion battery separators.
Lithium-ion battery separator is a very important component in the production of lithium batteries, and its main role is to isolate the positive and negative electrode materials, avoid short circuits and prevent short circuits inside the battery. The performance of the separator directly affects the safety and performance of lithium-ion batteries. The use of a diaphragm filter press can efficiently produce high-quality lithium-ion battery separators.
