Sodium-ion batteries have the advantages of long service life, wide range of suitable temperature, high magnification, easy manufacturing, low cost and high safety. China's first generation of sodium-ion batteries has been shipped in small batches in 2023. In 2024, sodium-ion batteries will achieve mass production, the scale is expected to reach 30GWh, with high energy density, high rate charging, excellent thermal stability, good low temperature performance and high integration efficiency. The energy density of the cell is as high as 160Wh/kg. Charging at room temperature for 15 minutes, the power can reach more than 80%; At -20°C low temperature environment, it also has more than 90% discharge retention rate; The system integration efficiency can reach more than 80%; Thermal stability far exceeds the safety requirements of national strong targets. The energy density of the second generation of sodium-ion batteries is more than 200Wh/kg.
