Introduction: Procurement Challenges in Battery Material Processing
In lithium battery manufacturing, twin screw extruders are key to achieving uniform and efficient slurry mixing for
cathode and anode materials.
However, screw elements are frequently exposed to abrasive powders, chemical solvents, and continuous shear stress, making material selection a critical factor for production
stability and maintenance costs.
For procurement professionals, the goal is to find a balance
between durability, cost-effectiveness, and supply consistency.
ZHITIAN’s TiCN (Titanium Carbonitride) screw elements offer a proven solution that meets these
requirements while ensuring compatibility with major extruder
systems.
Why TiCN Screw Elements Are the Right Procurement Choice
| Evaluation Criteria | Procurement Perspective |
|---|
| Wear Resistance | TiCN outperforms standard tool steel and PM alloys in abrasive
slurry mixing conditions. |
| Chemical Stability | Excellent resistance against NMP, lithium salts, and carbon-based
compounds. |
| OEM Interchangeability | Fully compatible with major extruder brands for direct replacement. |
| Long-Term Value | Extended service life reduces overall maintenance and downtime
costs. |
| Supply Reliability | In-house material development ensures steady quality and delivery
stability. |
Procurement decisions in modern extrusion lines increasingly focus
on total cost of ownership (TCO) rather than just purchase price. TiCN’s superior performance
delivers measurable savings throughout the equipment lifecycle.
Material Advantage: TiCN Alloy for Twin Screw Extruder Screw
Elements
Developed through advanced powder metallurgy, TiCN (Titanium Carbonitride) combines the best of both carbide
and nitride materials:
High hardness from TiC (Titanium Carbide) — provides outstanding wear resistance
Toughness from TiN (Titanium Nitride) — enhances impact and fatigue strength
Corrosion resistance — stable in chemical-rich lithium slurry environments
This unique balance of properties makes TiCN ideal for lithium-ion battery slurry mixing, solid-state battery materials, and other high-shear, chemically active extrusion processes.
Applications
TiCN screw elements are widely applied in:
Cathode slurry preparation (LFP, NCM, NCA, etc.)
Anode slurry mixing (graphite, Si-C composite, carbon black)
Binder and conductive agent compounding
High-viscosity electrode paste production
Pilot and mass production extrusion systems
ZHITIAN’s TiCN elements are available as OEM replacements or custom-engineered designs, ensuring perfect mechanical compatibility and consistent process
performance.
