High-Purity Lithium Battery Raw Material Supply for Energy Storage Power Battery Clusters in Poland
Project Background: Poland serves as the core hub of the lithium battery industry in Central and Eastern Europe, hosting production bases of LG New Energy and Northvolt as well as local energy storage integration enterprises, covering production systems for prismatic, pouch and cylindrical cells. The local low-temperature period lasts up to 5 months annually, with large day-night temperature fluctuations in factory storage and production environments. Fluctuating moisture content in NMP causes gelation of high-nickel cathode slurry; excessive moisture during electrolyte filling generates hydrofluoric acid, resulting in cell swelling and capacity degradation.
7dchem has deeply cultivated the lithium battery chemical supply chain in Central and Eastern Europe for 8 years, serving 7 local battery factories and 12 mass production cell lines with lithium raw material supply and technical services.
Original Pain Points:
Large temperature fluctuations in low-temperature storage and production environments make electronic-grade NMP prone to water absorption, triggering gelation of high-nickel cathode slurry and destabilizing coating processes.
Excessive environmental moisture in electrolyte filling procedures promotes hydrofluoric acid generation in electrolyte, leading to cell swelling, cycle performance degradation and reduced finished product yield.
Insufficient sealing of lithium hexafluorophosphate during long-distance low-temperature transportation leads to moisture absorption, decomposition and crystal precipitation, blocking feeding pipelines and undermining feeding precision and mass production stability.
7dchem Solutions
Core lithium battery raw materials: Battery-grade lithium hexafluorophosphate (main content ≥99.9%, free acid ≤50ppm, moisture ≤10ppm); electronic-grade NMP (chromatographic purity ≥99.9%, single metal ions such as Na, Fe, Ca <1ppb).
On-site technical implementation: A technical team led by Manager Guo with 10 years of R&D experience in electrolyte and cathode solvents delivers on-site services, including low-temperature raw material testing, commissioning of coating & electrolyte filling parameters, establishment of incoming inspection standards, and optimization of raw material drying processes to adapt to low-temperature mass production conditions.
Complete compliance system: Full EU REACH/CLP cross-border circulation compliance documents are provided to satisfy supplier admission and cross-region transfer requirements of battery manufacturers.
Warehousing & logistics: Two independent warehouse locations in Poland with constant-temperature storage, rapid allocation and shortened customs clearance cycles to sustain uninterrupted mass production supply.
Full-process new energy chemical service: Pre-review and filing of EU REACH/CLP compliance documents for new energy chemicals, verification of hazardous product qualifications, customs declaration, cross-border logistics trusteeship, constant-temperature storage in dual Polish warehouses, on-demand delivery for mass production, and continuous technical follow-up for production line processes, fully supporting lithium battery mass production demands.
Implementation Results
The optimized raw material drying and process solution tailored for low-temperature mass production environments completely resolves pain points including NMP slurry gelation, cell swelling and pipeline crystal blockage. It shortens cell standing production time, reduces defective rates, maintains stable raw material indicators, guarantees long-term stable mass production for local battery factories, and forms continuous repeat cooperation with clients.
Inquiry channel: Poland hotline: +48 732 084 37. Lithium battery raw material samples can be sent for customers to independently conduct tests on low-temperature adaptability, moisture stability and metal ion residue levels.
