Background and Requirements of the Zinc and Copper Prohibition Standard in the Lithium Battery Industry
With the rapid development of the global lithium battery industry, the industry has put forward stringent requirements for the safety of the production environment and the purity of materials. According to the GB/T 31241-2014 standard, the concentration of metals such as zinc and copper in the air of lithium battery production workshops must be strictly controlled below 0.5 micrograms per cubic meter. Zinc and copper elements may cause safety hazards such as self-discharge, diaphragm perforation, and even explosion during battery production. Therefore, from equipment accessories to production processes, it is necessary to achieve "zinc and copper-free" production.
BaLiWo full series of zinc and copper-free pneumatic products
To meet the needs of the lithium battery industry, Balew pneumatic launched a full material zinc-free copper solution, covering key pneumatic components:
Air source processor: It is made of stainless steel and high-strength aluminum alloy, with internal coatings and seals that have passed third-party testing. The zinc and copper content is less than 0.5%, meeting the requirements of GB/T 31241-2014 and the EU REACH regulation.
Solenoid valve and connector: The core components are made of ceramic or engineering plastic instead of traditional copper alloy, eliminating the risk of metal ion precipitation and adapting to high-sensitivity scenarios such as lithium battery slurry delivery.
Technical verification and market application
Third-party testing: The product has been certified by institutions such as SGS, with measured zinc and copper content far below industry limits (such as a zinc content of only 0.3% at the joint part), and possesses corrosion resistance, dustproof and explosion-proof characteristics.
Indonesian lithium battery project: It has been applied in batches to the production line construction of a leading battery manufacturer in Indonesia, including key processes such as cathode material coating and cell packaging. The operational stability has been recognized by customers.
Industry value
Balewo's solution not only helps enterprises avoid safety risks, but also promotes the localization of lithium battery equipment through material innovation. In the future, the company will continue to develop zinc-free copper technology to respond to the global "carbon neutrality" trend and upgrade demand for new energy equipment.
