Casting and Stretching Machine: The "Performance Alchemy Furnace" for New Energy Materials!
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 Ô¤Éè 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.
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!
