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 ±1%. 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：We 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.

Winder：We 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.

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：We 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.

【 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.
|
 |
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.
