Cutting-edge chemistry and shaped for efficiency


There are more than 200 professional engineers and technical staff to carry out cutting-edge technology research and development and process technology innovation. We are the only company in China that is able to research, develop independently and manufacture NiMH, LI-PO, LI-FE batteries at the same time. In addition we own the high level technologies in power batteries production.

Cutting Edge Materials

The surface-coated nano-ceramic battery separator has the advantages of high temperature resistance, high voltage resistance, high puncture and high liquid absorption, which can greatly improve the heat shrinkage of the diaphragm and improve the safety and reliability of the battery.

Cell Packing Technology

Our state of the art cell packing method is 100% autonomous, thus by eliminating the human factor we are able to create a controlled method for higher quality and uniformity of each batch.


The BATTERY MANAGEMENT SYSTEM is any electronic system that manages a rechargeable battery (cell or battery pack) and is the link between the battery and the user.


Each product is labeled with a bar code that can be traced from the time of mixing to the completion of the pack. Our multi-step procedure systematizes everything to ensure that not a single cell escapes quality control.
