3.4 Project Difficulties & VTON Professional Solutions
Difficulty 1: Strong corrosion and volatile leakage of electrolyte medium
The lithium hexafluorophosphate electrolyte has strong corrosiveness and volatility. Tiny leakage will cause clean workshop pollution and reduce battery yield. VTON adopts integral bellows seal structure to replace traditional packing seal, realizing zero external leakage. Hastelloy C276 wetted material effectively resists lithium salt corrosion, and each product is equipped with spectral material inspection report.
Difficulty 2: Slurry solid particle clogging and valve wear
Positive and negative electrode slurry contains a large number of solid powders, which is easy to block ordinary valves. VTON slurry-specific diaphragm valve has no flow dead angle, smooth flow channel, and PTFE anti-stick and anti-wear lining. The maintenance cycle is extended to 6 months, greatly reducing production line downtime.
Difficulty 3: Ultra-high precision batching requirements for electrolyte
Batching deviation over 0.3% will cause poor battery batch consistency. VTON Coriolis mass flow meter directly measures mass flow, which is not affected by temperature, pressure and viscosity changes. The 0.1% high precision realizes closed-loop automatic batching of DCS system.
Difficulty 4: Explosion-proof and clean room particle control
NMP solvent is flammable and explosive, and lithium battery workshops have strict cleanliness requirements. All VTON products pass explosion-proof certification and mirror polishing treatment, meeting ISO 5 clean room standards, with complete ACS sanitation certificate, hydraulic test report and NDT report.
3.5 Project Operation Benefit Data
