HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Under the backdrop of the continuous upgrading of the new energy industry, the stable supply of high-purity industrial gases has become a core link in the lithium battery manufacturing chain. Recently, the cryogenic high-purity nitrogen equipment specially designed for ATL by NUZHUO was officially put into operation. The successful delivery of this project not only indicates that NUZHUO’s technical capabilities in the field of cryogenic air separation have once again been recognized by industry leading customers, but also further confirms the reliability and competitiveness of China’s air separation equipment in the high-end battery manufacturing sector.

In the production of lithium batteries, the high-temperature sintering process of the positive electrode materials has extremely strict requirements for the atmosphere environment. To prevent the materials from having adverse reactions with oxygen during the sintering process, high-purity nitrogen gas is usually injected into the sintering furnace as a protective gas to ensure the stability of the electrode material structure and the quality of the product. With the continuous increase in the energy density requirements of batteries, the purity requirements of nitrogen gas have moved from industrial grade to electronic grade. Any trace impurities may affect the cycle life and safety performance of the battery.

This Cryogenic high-purity nitrogen equipment provided by NUZHUO for ATL is precisely optimized for this demanding application scenario. This device employs low-temperature distillation technology and can continuously output high-purity nitrogen gas with a purity of over 99.999%. It precisely meets the stability requirements of the battery production line for gas purity, dew point, and flow rate.

As one of the few domestic enterprises with the capability to design, manufacture and undertake the overall project for large-scale air separation equipment, NUZHUO has accumulated rich engineering experience in the field of cryogenic separation technology. In response to the specific requirements of the ATL project, the solution provided by NUZHUO has the following significant advantages:

High reliability and fully automated operation: The equipment is designed with a modular structure and a fully automated control system, ensuring ease of operation and reliability during long-term continuous operation. For global leading consumer electronics and battery power manufacturers like ATL, the safety and low failure rate of the equipment are essential prerequisites for achieving efficient production.

Low energy consumption and economic efficiency: By optimizing the structure of the distillation tower and the heat exchange process, this device not only achieves the extraction of high-purity products but also effectively reduces the energy consumption per unit of gas produced. In the current situation where the battery industry is under pressure to reduce costs and increase efficiency, this feature has created significant long-term operational value for customers.

Customized Adaptation: NUZHUO, based on the land conditions and gas consumption load of the ATL factory, provided customized flow path design and layout plans, achieving the optimal balance between equipment footprint and production capacity.The relevant person in charge of NUZHUO stated: “We are extremely honored to be a partner of ATL. The smooth operation of this project proves that NUZHUO’s cryogenic equipment is fully capable of meeting the ultimate requirements of world-class battery manufacturers for supply security and quality. In the future, we will continue to focus on technological innovation and provide more efficient and cleaner gas separation solutions for the global new energy, semiconductor and medical health industries.”
