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.


  • 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
Country/Region Patent Number
Japan 6380707
International patent PCT/JP2019/027179*
Many others (Japan, Europe, Kore, China, Vietnam, Singapore, Thailand, Malaysia, and others)

* Application Number

Negative Plate



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.
