LIFTTOP Traction Battery Overview
“LIFTTOP” is the new brand of our traction battery since 2020. We will continue to provide highly reliable and long-life batteries.
LIFTTOP Technologies
Positive Plate
[Pressure Casting Spine]
Our patented lead-alloy composition, enhanced with advanced technology to control the pressure casting of the positive spine is reliable, durable for usage in harsh environment and reduce self discharge rate.
Characteristic:
- Better corrosion resistance (Evaluated at 1200 cycles).
- Higher tensile strength of 1.5x higher than conventional type.
[Glass Fiber Clad Tube]
We adopted glass fiber clad tube that can prevent leakage of active materials during usage.
Our patented application of glass fiber also provides excellent heat resistance & chemical resistance which contribute the overall high performance of the battery.
[Positive Active Material]
The active material used on the positive plate is perfectly developed to greatly enhance the longevity and increase the high capacity of the battery.
Representative patents/patent applications
- Long-life technology with optimized glass tubes

Negative Plate
[Separator]
We have adopted sealed-up structure to reduce the risk of internal short circuit for the negative plate. This structure is designed in a unique way. Each of our negative plates is enveloped by polyethylene separator, which is sealed on all sides by mechanical seal and ultrasonic seal on the top side.
[Negative Active Material]
The reacting area has increased by about 20% in comparison with our conventional types. Thanks to the new negative electrode additives developed by our company, the discharge capacity at low temperature has increased about 10% compared with our previous model.
Representative patent applications/design patent applications
- Long-life technology with envelope type separator designed with a unique structure
