Lithium Battery Industry

In the rapidly developing new energy field, especially in the lithium-ion battery manufacturing industry, accurate temperature control is essential. With the increasing requirements for temperature control accuracy in the industry, traditional coal heating or steam heating methods have gradually been replaced by temperature control equipment such as mold temperature controllers and heating & cooling integrated machines. Hengde's mold temperature controllers (mold heaters，MTU， MTC), industrial chillers, heating & cooling integrated machines, oil chillers and other temperature control equipment are all designed to meet the strict requirements of lithium battery production lines.

The production of lithium-ion batteries involves multiple complex process flows that are extremely sensitive to temperature fluctuations. Stable and accurate temperature control ensures consistent product quality, improves output and production efficiency, and extends the service life of equipment. The lithium battery production process can be divided into three sections: front-end, middle-end and back-end.

The processes and corresponding equipment are:

1. Front-end process: The front end is the pole piece making link, which mainly includes stirring, coating, rolling, slitting and pole ear forming processes. The corresponding equipment is a coating machine, a roller press, a slitting machine, a tablet making machine, etc.

2. Mid-end process: The mid-end is the battery assembly process, which mainly includes winding, lamination, shelling, electrolyte injection and other processes, and the corresponding equipment is winding machine, lamination machine, etc.

3. Back-end process： The back-end is the electrochemical process, which mainly includes battery cell formation, capacity division, testing and battery assembly processes, and the corresponding equipment is formation cabinet, capacity division cabinet and mechanical welding machine, etc.

The front-end process is the core process of battery manufacturing, which is related to the quality of the entire production line. The quality of the battery pole piece depends on the quality of the front-end equipment. At present, Hengde mold temperature machine, chiller, heating & cooling integrated machine and oil chiller and other equipment mainly accurately control the temperature of the following equipment in the lithium battery production process:

1. Lithium-ion Battery Electrode Production;
2. Calendering Machinery;
3. Coating Machinery;
4. Roller Pressing Production Line;
5. Roller Press Slitting Integrated Machine;
6. PD Mixer + Feeding System;
7. Vacuum double-cone rotary dryer;
8. Plowshare mixing dryer;
9. Other custom thermal control systems.

Solution

One notable case involves a Japanese customer who previously used a local brand for lithium battery material production. Due to rising cost pressures, they switched to a well-known Chinese brand, only to face persistent oil leakage issues—caused by the supplier’s lack of experience in lithium battery applications. Seeking a better solution, they turned to HENGDE. We quickly identified the problem and provided a tailored fix, solving the issue without major equipment changes or downtime.

As a result, the customer made the strategic decision to standardize all mold temperature controllers and integrated heating & cooling units on their roller pressing production Line and roller press slitting integrated machine with HENGDE equipment. To this day, our systems continue to support their high-precision battery production with stable, reliable performance. And the customer said: “In the lithium battery industry, HENGDE’s mold temperature controllers and integrated heating & cooling units are undeniably the No.1 brand from China!”
