Core advantages
———
Excellent low-temperature performance
-Discharge 80% at 40 ℃, discharge 90% at -20 ℃, not afraid of severe cold challenges.
Longer cycle life
The energy density can reach 120Wh/kg, and the cycle life exceeds 6000cy;
Excellent magnification performance
Can achieve continuous 3C charging and 5C discharge, with 20C discharge for 10 seconds
Higher security performance
Capable of withstanding various extreme situations such as high temperature, high voltage, short circuit, etc., without the risk of explosion, fire, leakage, etc.
Diversified products
40/46 models, covering multiple fields, to meet the different needs of customers.
Significant cost advantage
Sodium resource reserves are more abundant than lithium mines, with no risk of choking; The negative electrode is made of aluminum foil, which has a higher cost performance ratio.

Technology Roadmap
———

The core technology team of Qingna Technology has been committed to the development and production of cylindrical batteries for a long time. As early as 2019, they began to enter the field of sodium batteries and successfully developed the industry's first fully automatic production line for all pole ear large cylindrical batteries from scratch.


Qingna Technology adheres to the technical route of "parallel layered oxide and polyanion" and is the first to launch the S40140RL full poleear large cylindrical steel shell sodium ion battery cell. It has achieved comprehensive leadership in range, safety performance, low-temperature performance, rate performance,and batchproduction stability.

At present, the first generation layered oxide product developed by Qingna has reserved three mass production systems and achieved large-scale delivery; The second generation product is currently being validated and optimized, and is about to be launched into the market.


Application Area
———

Qingna Technology is committed to the full scenario application of sodium ion batteries. With stable batch supply capacity, Qingna has fully blossomed in the fields of light power, construction machinery, industrial and commercial energy storage, UPS, and start stop power supply, and has reached cooperation with multiple leading enterprises.
