Continuous Homogenization Process, the New Breakthrough in Lithium Battery Production!

The pole piece plays an important role in lithium batteries, whose manufacturing is completed by coating.


The coating here refers to the covering of the prepared electrode slurry on the current collector (cathode uses aluminum foil and anode uses copper foil). Therefore, the coating directly affects the quality of the electrode sheets. In other words, the quality of a battery mainly depends on the quality of the electrode sheets. The formula, the fineness, the uniformity of dispersion, viscosity, adhesion, stability, and consistency of the slurry have a significant impact on the performance of lithium batteries and it is also to measure whether the slurry is qualified.


The lower fineness makes less scratches during the coating process and the higher viscosity makes it easier to bond the slurry on aluminum and copper foil.


The lithium-ion battery homogenizing process is to prepare for the pole piece production.


LONGLY has profound technical accumulation in the field of homogenization, especially in the field of battery homogenization, with extraordinary achievements. Over the years, we have been committed to researching homogenization technology, continuously deepening its understanding of industry needs, and continuing to invest in research and development. Nowadays, LONGLY has successfully developed a series of product matrices such as dual planetary mixers, the high-efficiency homogenizer, and the twin-screw homogenizer, becoming one of the few companies in the industry that masters the corresponding processes and equipment.


Twin-screw Continuous Homogenization Process

▲ Twin-screw Continuous Homogenization Process


Among them, the continuous homogenization process is derived from the twin-screw extruder. Different raw materials are added to the twin-screw extruder according to their respective ratio, and through a loss-in-weight feeder, the powder is premixed. Subsequently, the premixed powder is mixed with different liquids according to a specific ratio. Then it gets meshed, sheared, and dispersed in the twin-screw host allowing the materials to get completely dispersed during mixing.


The entire process is completed in the narrow and long barrel of a twin screw. Process design and equipment operation is crucial to ensure the uniformity and quality of mixing. The continuous homogenization process not only improves the mixing, but also optimizes the production process, saves costs, and injects new vitality into the development of the industry. The continuous improvement and innovation of processes will continue to push the industry forward, achieve higher quality and more efficient production, and bring more opportunities and challenges to the entire industry.


Dual Planetary Mixing System

▲ Dual Planetary Mixing System


The dual planetary mixing system includes ton bag feeding station, small bag feeding station, powder storage tank, weigher, pre-mixer, gel maker, liquid metering tank, electromagnetic filter, a dual planetary mixer, dual planetary mixing system, and MES system, etc.


It is efficient and reliable for the entire homogenization process, greatly improving production efficiency and quality. Every process of the dual planetary homogenization system has been carefully designed and strictly tested to ensure stable and smooth operation. The ton bag feeding and small bag feeding stations provide a convenient and fast way to input raw materials. The powder buffer tank and loss feeder cooperate with precise control to ensure the accuracy of the raw material ratio. The pre-mixing tank and the glue-making tank fully mix various raw materials. The liquid storage and metering tank accurately controls the amount of liquid added, and the electromagnetic filter can eliminate impurities and ensure the purity of the product.


The dual planetary mixer with the unique dual-shaft operation fully mixes the raw materials. Also, the entire system is equipped with an advanced MES central control system for precise management and production process monitoring.
