The solid-state battery cell hot-press forming machine is mainly used for controlled heating, pressing, pressure holding, and forming of solid-state/semi-solid-state battery cells, electrode–solid electrolyte composite layers, stacked cell units, and small cell assemblies. It is suitable for material system screening, process window development, sample preparation, R&D validation, and pilot-scale small-batch production.
The equipment adopts a high-rigidity frame and precision guiding structure, combined with a servo electric cylinder or servo-hydraulic closed-loop pressure control, multi-zone temperature control, and a PLC-based automatic control system, enabling programmable control of key process parameters such as temperature, pressure, displacement, and time.
For different solid-state battery material systems, functions such as vacuum, inert atmosphere, low-dew-point environment docking, rapid cooling, online thickness measurement, automatic loading/unloading, and MES can be optionally added.
PRODUCT DESCRIPTION
1. Precise Pressure Control
Supports multi-stage pressure profiles such as pre-pressing, stepped pressure increase, ramp pressure increase, constant-pressure holding, and gradual pressure release. Through pressure closed-loop control and displacement monitoring, the stability of the hot-pressing process is improved.
2. Uniform Temperature Control
The upper and lower hot platens are independently PID-controlled, with expandable multi-zone temperature control. While ensuring heating efficiency, it also takes into account temperature uniformity in the working area, and is equipped with independent over-temperature protection.
3. High-Rigidity Precision Pressing
Adopts a high-rigidity frame and precision guiding mechanism to improve platen parallelism and repeated positioning accuracy during loading, meeting the requirement for uniform pressure on large-area cells.
4. Process Data Traceability
Supports ≥100 process recipes, can record information such as pressure, temperature, displacement, time, batch, and alarms in real time, and supports historical curve query and data export.
5. Comprehensive Safety Protection
Equipped with multi-level safety measures such as safety door interlock, emergency stop, over-pressure, over-temperature, sensor abnormality, drive abnormality, and electrical protection.
