Recently, Fineng Technology stated that 's sodium ion battery product is in the centralized sample delivery stage and has currently met the needs of A0-level cars.
The company plans to fully enter the sodium battery industrialization stage by 2023, and has carried out in-depth cooperation with many well-known two-wheeled car companies and passenger car companies, with the goal of meeting the needs of A-class cars in 2024.
According to reports, sodium ion batteries are currently in the promotion period. With the improvement of industrial chain , the improvement of technology maturity and scale effect, the cost of sodium ion batteries is expected to be more than 20% lower than lithium iron phosphate batteries, which is also of great significance to the popularization and promotion of electric vehicles.
Moreover, as the key problems in the application of sodium ion batteries are gradually overcome, some performance indicators are comparable to lithium batteries, and the energy density of sodium ion battery cell monomer can reach 140-160Wh/kg, close to the level of LFP (lithium iron phosphate battery).
From the perspective of fast charging and low temperature performance, the sodium ion battery product previously released by CATL
can reach 80% of the capacity after charging for 15 minutes, and can still maintain a discharge retention rate of more than 90% in a low temperature environment of minus 20℃.Compared with lithium batteries, especially lithium iron phosphate batteries, sodium ion batteries have no obvious disadvantages except for their weak energy density. Industry analysts pointed out that after sodium ion is mass-produced and commercialized in the future, consumers may buy electric cars at a lower price.
