Technical R&D is in an important position of the company development. Through rigorous R&D organization, advanced R&D equipment, and huge amount of R&D investment, we has achieved industry-leading R&D achievements.

Our strong R&D team brings together talented people in local and international lithium battery industry and is committed to providing customers with the best power supply design solutions. At present, we have developed large, medium and small capacity series of more than 200 LiSOCL2 battery models and 500 Ultra thin battery single cell capacity of Lipo battery ranges from 30mAh to 15Ah, including conventional performance products, low or high temperature products and high discharge rate products. In response to different customer needs and different product application requirements, we are constantly developing and designing new models of products: LiFePO4 batteries and Portable power station. At the same time, we continuously improve the performance of battery safety, energy density, temperature characteristics, discharge platform, impedance, and cycle life, develop products with outstanding combination of performance.

We have a professional and strong technical team to coordinate with the customer's design and development process, design and develop according to the needs of customers, and help customers quickly realize product solutions. For development of new models, it usually takes only 20 days from receiving the development of the requirements to the completion of the sample.
