¡¾ Coating ¡¿

Mixing: The pug mill used for mixing is 3 oars with high & low speed available and vacuation and cooling functions. This ensures the mixed material is uniform and has no mass or air bubble. So it ensures the consistency of coating and high quality of products.

Coater: Our company is the first one to use the high-precision coater produced by TORAY Japan. The density tolerance of the single electrode plate is less than ¡À1%. The tolerance of electrode board length and gap dimension is less than 1mm. This kind of coating is far superior to the rotating coating on uniformity and consistency.

Calender: We use the sequential rolling equipment produced by IMC and IMD USA. The taper of rolling is 2um, which ensures the consistency of thickness of electrode boards. This equipment is equipped with perfect clearing system, which avoids the tiny short-cut due to dust particles and accordingly improves the battery¡¯s charge performance.

Slitter£ºWe use the sequential slitting equipments produced by TORAY Japan. The slitting blade is roller-type blade. The electrode board slit has no defective edge or burr or other defects. Meanwhile, the equipment is equipped with perfect clearing system, which ensures and improves the battery¡¯s charge performance.



¡¾ Winding ¡¿
Winder£ºWe import the winder from JAIDO Japan. This equipment can ensure the electrode board, separate and tension is invariable during the winding process. It also ensures uniformity and stability in chemical reaction of electrode. This ensures the performance consistency of battery. In addition, the exact correcting system (8 EPC correction, the correcting precision is 0.1mm) can ensure safety of battery. We use reliable ultrasonic jointing machine produced by BRANSON USA to weld electrode board and electrode ear. We use insulative impedance tester to test each winding automatically. This tester judges the tiny short-cut as NG and eliminate it automatically to ensure the reliability of battery.


¡¾ Jointing ¡¿

Assembly line: The multi-units and multi-types semi-automatic assembly equipments manufactured by ourselves reduce the transmission time (reduction above 5 times). The key working procedures (bending electrode ear, pressing cells, cover£©are all finished automatically. This equipment can switch the types very expediently and avoid long adjustment. So it has very good performance and cost advantages.

Laser jointing£ºWe use 200W pulsed laser jointing machine. This machine uses two-axis precision control worktable. The repeated precision is less than 0.01mm. The pulse width, frequency, current, current and output wave can be adjusted. The jointing contrail can be programmed. We use the home-made clamps with high precision. Its mounting precision is calibrated by gauge. So we can ensure the good laser affinity for both imported can and domestically-produced can. To ensure the jointing reliability, we use home-made leak detector for each can to conduct random testing and to adjust parameters to ensure the reliability of battery.



¡¾ X radial machine test ¡¿

X-Ray test: We can observe the internal structure and electrode insulation by using the X- radial machine, which can effectively ensure the safety performance of the battery.


¡¾ Filling ¡¿

Filling: We have nearly 500©O hothouse. The USA MUNTERS dehumidification equipments can ensure the HR is under 1%£¨dew point¡´-40¡æ¡µ£©. Under the very dry condition, we adopt vacuum filling to reduce the water-absorbing rate of electrode boards and electrolyte a lot; We use pumps with high precision to keep good consistency of filling quantity.

Automatic sealing: The automatic capper developed by ourselves has many advantages, for example, high sealing speed, stable sealing pressure, good consistency of steel balls height. This capper can prevent moist air from entering after pre-formation, which can improve cycle and safety performance and control the distension of battery.



¡¾ Formation ¡¿

Formation system: The formation system with high precision used by us can test all performances of battery, for example, internal resistance, capacity, discharge platform, curves of charge and discharge, cycle life and so on. This system also can classify battery according to different performance target.
