QINKUAL specializes in the research and production of lithium battery cells.
After 9 years of technical precipitation, we have accumulated a wealth of research and development results in battery materials, cell technology and cutting-edge theories, formed 4 independent core technologies and filed more than 80 patents. On this basis, we have successfully built two technical platforms with the core competencies of "ultra-wide temperature range - ultra-high multiplier" and "ultra-long life - high multiplier - large capacity", and successfully launched three series of high-end energy storage core products for the energy storage market. One of the key research and development areas for ultra-low temperature and ultra-high capacity battery cores, successfully breakthrough the LFP battery core with -60℃ cold start, -20℃ charging performance and 55C ultra-high capacity discharging performance. The corresponding products have passed the national standard for power and energy storage, as well as UL1642, UL1973, IEC62619, IEC62620, UN38.3 and other certifications, and thequality system has obtained the German IATF16949 certification.
Since the introduction of the "QINKUAL" brand, based on solid research and development support and excellent production management, the product has won recognition in the industry and market. Customers include a number of well-known domestic and foreign enterprises, the market includes data center UPS, power frequency control, PHEV, start-up power supply and other fields. QINKUAL" will continue to focus on innovation in battery technology, promote the development of green carbon-free energy, and strive to become the world's leading supplier of "full temperature range and high magnification" battery.
