Far ahead, leading the new trend of power

Since its establishment, Qingna Technology has relied on its unique strategic vision and adhered to the parallel technical route of layered oxides and polyanions, and has obtained a number of core patents for sodium electricity. Developed independently by the companyS40140all-pole earLarge cylindrical steel shell sodium ion battery cell, achieving comprehensive leadership in terms of cruising range, safety performance, low temperature performance, rate performance, and mass production stability. Currently, this product has been delivered in batches and is far ahead in the industry! ! !

With its excellent performance advantages, Qingna Technology has attracted the favor of Jinpeng Group, Zhongke Hainan, Nanzi Tonghua, Dayun Automobile, and many leading engineering machinery companies. In January this year, Qingna Technology signed a strategic cooperation agreement with Jinpeng Group, with an initial target purchase volume of 1.75GWh/year.This is a representative cooperation with clear demand in the current sodium power industry.。

Battery life increased by 30%, solving tricycle mileage anxiety

On November 6, the company received a road test evaluation report from Jinpeng Group: the 60V30Ah sodium-ion battery pack produced by Qingna Company was loaded on a Jinpeng electric tricycle for a road test and showed excellent performance in all aspects, especiallyThe cruising range is up to 43km, which is much higher than the 33km of ordinary batteries.. This road test evaluation report is not only a high recognition of the performance of Qingna Technology’s products, but also lays a solid foundation for the subsequent cooperation between the two parties.

Joining hands with Nanzi Tonghua, sodium power storage will regain its strength

In addition to its outstanding performance in the power field, Qingna Technology is also making great moves in the energy storage market. On November 8, Qingna Technology and Jiangsu Nanzi Tonghua Smart Energy Co., Ltd. signed a strategic cooperation agreement. The two parties will cooperate in the fields of industrial and commercial energy storage, photovoltaic energy storage, data center UPS and industrial power backup, and give full play to their respective advantages. , join forces to bring safer, more cost-effective, and more stable quality sodium battery energy storage systems to the market. According to the agreement,Nanzi Tonghua will purchase no less than 2GWh of sodium-ion batteries and modules produced by Qingna Technology within three years.

Prior to this, Qingna Technology had signed a strategic cooperation agreement with a large foreign energy storage company, and the intended cooperation demand of both parties exceeded 20GWh.

Leading technology, mastering the core patents of sodium electricity

Qingna Technology cooperates with Beijing Graphene Research Institute, University of Science and Technology Beijing, Lanzhou University, Jiangnan University and other well-known universities, has established a scientific research team with strong technical strength, and has obtained a number of core patents for sodium electricity. Qingna Technology’s mass-produced layered oxide sodium-ion batteries have an energy density of up to 120Wh/kg and a cycle life of over 6000cy; the latest generation of layered oxygen batteries in reserve have an energy density of up to 145Wh/kg. Based on application needs, Qingna Technology has launched a low-cost polyanion sodium-ion battery for the energy storage market, with an energy density of 100Wh/kg and a cycle life of over 8000cy.

Rapid development, attracting many venture capital investors to join

With its strong scientific research strength and mass production advantages, Qingna Technology has attracted a number of listed companies and industry giants as strategic shareholders with venture capital and long-term continuous capital support, and has reached comprehensive strategic cooperation with key raw material suppliers and equipment suppliers.

In the next three years, Qingna Technology plans to build three major bases with a total investment of over 5 billion yuan. The company has built a 200MWh quasi-mass production line in Huzhou in April 2023, and has laid out a 10GWh production capacity base in Guangde. It has achieved mass production of a 2GWh production line in 24 years. In 2026, we built a 20GWh production capacity base in the southwest industrial cluster, carried out comprehensive layout in the entire upstream supply chain and downstream domestic and foreign customers, and became a leading enterprise in the field of sodium power.
