Temperature and humidity

our factories are equipped with large-scale industrial dehumidifiers manufactured in Switzerland. Each workshop is thoroughly sealed, and the temperature and humidity are centrally controlled. 

Blender

The battery materials need to be stirred evenly without any air bubbles

Coating machine

LiPo batteries must have strong endurance and uniform capacity. This depends on the material coating on both sides of the cathodes and anodes being uniform.

Roller

Two pairs of large rollers weigh 12 tons. Under the control of the computer, the gap between the two wheels can be adjusted at any time. The thickness error of the extruded film is 0.0001 mm, ensuring that each battery has the same high capacity density.

After lipo batteries are produced, they must not only undergo high-temperature aging but also withstand 95% relative humidity at high temperatures.
