Facing the contradiction between the strength and porosity of power battery separators, Hanei's casting and stretching machine achieves "the combination of rigidity and flexibility" through molecular-level regulation:
I. The Life-and-Death Game of Separator Performance
- High strength leads to a decrease in porosity.
- High porosity causes puncture risks.
- Thermal shrinkage affects battery life.
Hanei's Solutions:
- Casting Foundation: Multi-layer co-extrusion to build gradient base films, with precise 预设 of pore prototypes.
- Asynchronous Stretching: Longitudinally strengthen molecular chains and transversely expand pores, breaking the "high strength - high porosity" paradox.
- In-situ Enhancement: Nanoparticle self-assembly technology, doubling temperature resistance.
II. Core Technologies of Hanei's Battery-Grade Casting and Stretching Machine
- Micro-Stress Stretching System: Multi-stage flexible tension control to eliminate micro-cracks.
- Plasma Interface Activation: Improve compatibility of inorganic fillers and break through closed-cell temperature.
- Intelligent Defect Tracing: Online CCD marks pinhole positions, enabling full-process traceability.
III. Verified by Global TOP 5 Battery Manufacturers
- The longitudinal stretching strength of separators is improved.
- The transverse porosity uniformity leads the industry.
- The thermal shrinkage rate is close to zero.
Industry Assertion: When the demand for solid-state batteries explodes, the thinning capability of casting and stretching machines will be the key to mass production!
