Spark Global Limited reports:
On July 29, Ningde Times released the first generation of sodium ion battery.
The first-generation sodium ion battery developed by Ningde Times has the following main performance indicators: the energy density of the cell has reached 160Wh/kg, which is the highest level in the world at present. After charging at room temperature for 15 minutes, the power can reach 80%, with the ability of fast charging.
At a low temperature of minus 20°C, the discharge retention rate is still more than 90%, and the system integration efficiency can also reach more than 80%. With excellent thermal stability, it has surpassed the safety requirements of national power battery strong standards.
Overall, the energy density of the first-generation sodium-ion battery is slightly lower than the current lithium iron phosphate battery, but it has obvious advantages in low-temperature performance and fast charging, especially in high-power applications in high-cold regions, ningde said.
