The GODO Pumps for Safer Battery Production

Nov,14,2025

New energy lithium batteries use lithium metal or lithium alloys as electrode materials and non-aqueous electrolyte solutions. Due to the highly reactive nature of lithium metal, production environments demand extremely strict controls. With the rapid development of the new energy vehicle industry, lithium batteries have become the core power source in the new energy sector. So, why must zinc and copper elements be prohibited in new energy lithium battery production workshops?

Zinc is an active metal, and copper, as a transition metal, also exhibits certain reactivity. During the lithium battery production process, simultaneous reactions occur at the positive and negative electrodes. If metal impurities are present, they can interfere with the formation of the potential difference, hindering the proper establishment of the primary battery structure. More critically, when metal impurities like copper and zinc mix into the cathode material and gradually accumulate, deposited metal formations with sharp edges can pierce the battery separator. This may lead to self-discharge of the battery and, in severe cases, even cause rupture.

For safety reasons, the introduction of copper and zinc elements must be strictly prevented in lithium battery production workshops. Even equipment used for transporting lithium battery slurry must be specially designed to ensure no contact with these metals.

The all-new fourth-generation diaphragm pump from GODO PUMPS—the dedicated pump for new energy lithium batteries—is born for this very purpose. It contains no copper or zinc in its material composition, perfectly meeting the stringent requirements of the new energy and new materials sectors, making it the ideal choice for lithium battery slurry transportation. Let's take a closer look at its core advantages:

  • 1.  Designed specifically for new fields, meeting the unique needs of new materials and new energy production.
  • 2.  Enhanced protection for the intermediate body effectively safeguards bearing operation and significantly extends service life.
  • 3.  Solves leakage issues, with a more wear-resistant pump body that easily handles complex working conditions.
  • 4.  Added pressure protection device at the pump port can replace pressure relief valves, improving work efficiency.
  • 5.  Complete exclusion of copper and zinc materials prevents adverse reactions with the slurry.

Leveraging years of industry application experience, GODO PUMPS has developed this dedicated diaphragm pump specifically for energy storage lithium battery production. Its lightweight pump body, sophisticated structure, and excellent operational stability make it an outstanding choice for slurry transportation equipment in the new energy and new materials fields.
