With the launch of?electric vehicles?in recent years,the demand for?lithium batteries?has continued to grow,and this trend will continue to rise in the future. At the same time,the global lithium-ion battery production facilities have entered a new cycle of scale expansion.

With the relevant polices issued with various countries to reduce carbon emissions.therefore, some battery manufactures need to continuously increase the production capacity of?lithium-ion batteries?for electric vehicles.The primary problem faced by power battery and even new energy manufactures and how to reduce costs and energy-saving ,realize low-cost operation of the?dehumidification?process while increasing corporate profits.

Why need dehumidification in lithium battery production workshops?

Lithium and other materials are highly reactive to moisture,so when they are used as the basis for battery production,controlling humidity in the production workshops to ensure?drying air?is essential in production operations.this will provide high quality products and output,and provide employees’s safe working space. Issued with humidity can cause respiratory diseases of the human body,reduce the uptime of production workshops,and lead to product losses,high costs,and negative effects for brand reputation.

The?humidity control?in the production workshop is significant and has a great impact on the quality of the product.therefore,every manufacture needs to clearly understand why the room needs drying air and how to ensure that they choose a humidity solution that suits them and is satisfactory.

The accepted dew point for?lithium battery production?is -40°C.but the dew point may decrease due to the chemical composition of the battery being more sensitive to moisture.So for high-volume production ,creating a dry room is the only alternative to ensure the quality of the product.

How it work?

The dew point of the?drying room?is -40°C.Equivalent to about 0.08g/kg(grams of moisture per kilogram of dry air),0.05gr/Ib or 79PPMw.

The way to achieve the best drying charmber is through the?desiccant rotor.our?dehumidification rotor?can absorb moisture from the outside humid air through the rotation of the?dehumidification wheel?and then process the air through the regeneration zone to further adsorb the moisture.while the regeneration temperature of the traditional dehumidification system is 120-140°C,the current regeneration temperature of our medium temperature regeneration?dehumidification system?only needs to be 80-90°C for desorption.

Puresci launched the fourth-generation dual-wheel low dew point and medium temperature regenerative dehumidification system,which has been practically used in the lithium battery dehumidification industry and has made breakthroughs in cost reduction and energy-saving.

How to reduce emissions?

In order to better realize the use of new renewable energy methods,puresci has cooperated with the world-renowned independent manufacture of refrigeration compressors-Bitzer?to jointly develop a dehumidification and?air conditioning system?for the lithium battery industry(coupling of heat pump and wheel system).puresci independently developed a medium-temperature regenerative dehumidification system and high-temperature heat pump equipped with Bitzer compressors to provide users with high-efficiency and high-performance dehumidification air-conditioning units

Users can not only energy-saving through the?heat pump,but also obtain the best heat recovery effect in the application of the medium temperature regeneration system,further reducing cost.
