Client: Institute for Advanced Materials Science (IAMS), Aachen, Germany
Supplier: Guangzhou Zoli Technology Co.,Ltd. Advanced Milling Solutions
Product: XQM-0.4L Planetary Ball Mill
Key Feature: Custom-equipped with 100ml Stainless Steel Vacuum Tanks and Nitrogen Gas Inlet System.
Application: Synthesis of air-sensitive electrode materials for next-generation solid-state batteries.
The Institute for Advanced Materials Science (IAMS) in Aachen, Germany, a leading research center in energy storage, required a high-performance milling solution to synthesize novel, air-sensitive nanomaterials. Their research on lithium-metal anodes and sulfide-based solid electrolytes was hampered by oxidation and moisture sensitivity during the mechanical alloying process. Guangzhou Zoli provided a customized XQM-0.4L with Planetary Ball Mill equipped with specialized 100ml stainless steel vacuum tanks and an integrated nitrogen gas inlet. This solution successfully enabled IAMS to conduct contamination-free milling in an inert atmosphere, accelerating their R&D cycle and yielding highly pure, consistent materials for their battery prototypes.
IAMS is at the forefront of developing next-generation solid-state batteries, a technology promising higher energy density and safety over conventional lithium-ion batteries. A critical step in their process is the mechanical alloying and mixing of precursor powders to form complex, metastable phases.
Primary Challenges Faced by IAMS:
Material Sensitivity: Their key materials, particularly lithium metal powders and thiophosphate compounds, are extremely reactive. Exposure to even trace amounts of oxygen or moisture during milling leads to the formation of oxide/hydroxide layers, fundamentally altering the material's properties and rendering it useless for high-performance batteries.
Contamination from Conventional Milling: Standard planetary ball mills operate in ambient air. Grinding jars made of materials like Nylon or PTFE could introduce organic contamination, while standard steel jars could cause iron contamination, both detrimental to battery performance and lifespan.
Need for Process Reproducibility: To achieve reliable and publishable scientific results, IAMS required a highly reproducible milling process where the atmospheric conditions could be precisely controlled for every experiment.
After a thorough technical consultation, Guangzhou Zoli recommended and supplied a XQM-0.4L Planetary Ball Mill with the following critical customizations:
Planetary Ball Mill Base (XQM-0.4L): A robust and reliable platform known for its stable rotational speed (0-870 RPM), programmable timers, and reverse function, ensuring consistent and powerful grinding energy.
100ml Stainless Steel Vacuum Tanks: Custom-fabricated from 304 Stainless Steel, chosen for its high mechanical strength, corrosion resistance, and low contamination risk for the target materials. Each tank was precision-machined to ensure a perfect seal.
Integrated Vacuum and Nitrogen Gas Inlet System: The core of the solution. Each tank lid was fitted with a dedicated valve system featuring:
Vacuum Port: Allows the chamber to be evacuated to below 1 Pa, removing all ambient air and moisture.
Nitrogen Inlet Port: Enables the purging of the evacuated chamber with high-purity (99.999%) argon or nitrogen gas, creating a completely inert milling environment.
Pressure Relief Valve: For safe operation.
The entire system was designed for easy operation: Evacuate the tank, refill with inert gas, and repeat 2-3 times to ensure absolute atmospheric purity before commencing the milling process.

The order was processed efficiently. The mill and its accessories were carefully packaged in anti-vibration and moisture-proof materials. All documentation, including a detailed operation manual, technical datasheets, and a certificate of conformity (CE Marked), was provided in both English and German to ensure smooth integration.
Logistics: The shipment was dispatched via a reliable international air freight carrier with door-to-door service to Aachen. All necessary customs documentation for Germany was prepared in advance, ensuring a swift clearance process. The unit arrived at IAMS within the promised 10 business days.
The implementation of the customized planetary ball mill had an immediate and significant impact on IAMS's research capabilities.
Elimination of Oxidation: The vacuum and nitrogen system completely prevented oxidation and hydrolysis of sensitive materials. Post-milling X-ray Diffraction (XRD) and X-ray Photoelectron Spectroscopy (XPS) analysis confirmed the synthesis of phase-pure, uncontaminated target materials.
Enhanced Material Purity: The use of stainless steel vacuum tanks eliminated the risk of organic contamination from polymer jars, a critical factor for the long-term cyclability of the developed batteries.
Superior Process Control and Reproducibility: Researchers could now precisely replicate the inert atmosphere for every experiment. This led to highly consistent milling results, strengthening the validity of their data and accelerating the optimization of material compositions.
Accelerated R&D Timeline: By solving the fundamental problem of atmospheric contamination, IAMS was able to reduce failed experiments and iterate much faster on their material designs.
