The horizontal hot pressing machine for soft pack batteries is a device used for the hot pressing process of polymer soft pack lithium batteries. Its core function is to complete the formation (activation) and shaping of the battery under heating and pressure conditions.
Features
Structural design: Adopting a horizontal dual station design, multi-channel stacking, and flexible use.
Process control: It can achieve multi-stage heating and pressure conversion, and each temperature and pressure can be independently set. Equipped with high-precision sheet heaters, with good temperature uniformity and long service life; Cylinder driven, pressure closed-loop control, pressure plate specially processed for high precision and minimal thermal deformation.
Fixtures and Testing: The design of positive and negative terminal ear wiring fixtures ensures good and stable contact. Standard battery analyzer, customizable according to requirements, capable of constant current charging, constant voltage charging, constant current discharging and other operations.
Automation control: Adopting PLC control and HMI operation, it is designed with various alarm and protection functions, such as high-level alarm lights, emergency stop buttons, fire alarm protection, etc., to ensure the safe and reliable operation of the equipment.
Improve production efficiency: The baking and shaping process can replace the existing battery formation process, shorten the formation time, shorten the battery production cycle, and reduce labor costs.
Improving battery performance: In a hot press environment, it can promote the infiltration of electrolyte inside the battery, form a denser and more stable SEI film, reduce the internal resistance of the battery, improve the cycle life and consistency of the battery, and make the surface of the battery smoother and more beautiful after vacuum sealing.
Technical upgrade direction
Miniaturization and portability: Developing small devices suitable for laboratory research and development, supporting rapid process validation;
Intelligent combination: combined with headspace sampler, mass spectrometer and other equipment to achieve online monitoring of battery gas production analysis;
Green manufacturing: Optimize the energy efficiency of heating systems, reduce equipment operating energy consumption, and meet carbon neutrality goals.
