Zhejiang Qingna Technology Co., Ltd.'s 10GWh mass production line has started construction......

      On April 9, the first phase of Qingna Technology’s 10GWh annual sodium-ion large cylindrical battery construction project started in the Yangtze River Delta (Huzhou) Industrial Cooperation Zone. The annual 200MWh sodium-ion battery pilot line also successfully reached production and rolled off the production line on the same day.

Wang Zixuan, chairman of Sodium Technology, said: This project is expected to have a total investment of 10 billion yuan and a total planned production capacity of 40GWh. It will be carried out in three phases. The first phase is planned to build 10GWh. It is expected to build the world's first sodium-ion battery production line to achieve mass production and commercialization.In fact, as a participant and resource integrator in the sodium battery track, Qingna Technology has received great attention from the upstream and downstream of the industrial chain and the capital market from the beginning.

      At the project opening ceremony, heads of leading upstream and downstream sodium power companies gathered togetheron site, witness the Zhejiang QingnaGroundbreaking ceremony。Including Lu Shouguang, chairman of Jinpeng Group, Yuan Qinshan, chairman of Universiade Group, Lin Xiaohu, vice president of Geely Commercial Group, He Zhonglin, chairman of Rongtong Hi-Tech, Li Yunfeng, president of Duofuoduo, Ye Yuting, chairman of Yiming Technology, and general manager of Zhongke Haina Li Shujun, Tianmu Pioneer Chairman Luo Fei, Jiangsu Xiangying Chairman Xu Zhen, Husong Intelligent Chairman Li Yuanlin and other industry chain enterprise leaders were all present. At the same time, including Leapmotor, Tianci Materials, Beterui, Rongbai Technology, key new energy equipment manufacturing enterprises and some investment institutions also came to the scene for exchanges and visits.

      As an important participant and resource integrator of the sodium battery platform, Zhejiang Qingna Technology Co., Ltd. will continue to delve into the field of sodium power based in Huzhou, actively leverage the advantages of chain owners, establish strategic cooperation with key upstream and downstream leading enterprises in the industry, and continue to promote sodium The battery industry continues to grow and develop.The 10GWh sodium battery production capacity planned by Qingna Technology this time also chose the large cylindrical route. At the exchange meeting, Chen Yunji, chief technical engineer of Qingna, introduced that using large cylinders as carriers, Qingna combines the low-temperature resistance and high-rate characteristics of sodium-electric materials, and uses technologies such as full-pole ears to give full play to the advantages of sodium-electricity and create high-quality products. Sodium battery products.It is understood that Qingna Technology has previously formed an expert team including a professor of industry-education integration from the Ministry of Industry and Information Technology, a PhD in materials science from Tsinghua University, and a motor electronic control and chip development technology team including the former chief scientist of BAIC, and has mastered the leading position in the industry. The development and manufacturing technology of large cylindrical batteries is fully combined with the low-temperature performance, fast charging and discharging of sodium batteries to optimize and improve the process and key capabilities. Based on previous technology accumulation, Qingna Technology launched its first product, the 40140 full-lug large cylindrical steel shell sodium-ion battery. This product adopts the layered oxide + hard carbon route, with an energy density of 145Wh/kg and a cycle of more than 3000cy. Its performance has surpassed that of lead-acid batteries and is gradually approaching the conventional characteristics of lithium batteries. In terms of low-temperature performance, the battery's capacity retention rate at -40°C is still over 80%, and its capacity retention rate at 0°C is as high as 99%.

Qingna Technology's sodium-electric large cylindrical battery structure avoids a series of problems such as flatulence and circulation in square and soft-pack structures. The steel shell packaging effectively ensures battery safety; it further improves energy density on the basis of improving production efficiency and reducing costs.In addition, this product uses full-tab technology to give full play to the sodium electromagnetic rate characteristics. The specific performance is as follows:forIt can be charged to 80% in 15 minutes, and the pulse discharge current can reach 10C. The sodium batteries produced by Qingna will provide better solutions for various new energy application scenarios with excellent electrical properties and highly competitive costs, helping the world's new energy market develop faster and better。
