After lithium prices rose due to supply chain difficulties, low-cost sodium-ion batteries became attractive to many related parties within the Chinese market.
On September 18, the Chinese battery company, Catel, revealed that the upstream manufacturing supply chain for sodium-ion batteries will be completed and go into production next year, and that research continues to improve production. of these batteries in 2023, and launched its first generation of sodium ion batteries at the beginning of July 29, 2021.
Two years ago, the price of lithium carbonate for batteries was only 40,000 yuan (5,710 US dollars) per ton, but since September 16, 2022, the price has risen to 502,500 yuan per ton, an increase of 1156.25% in two years.
In the period January-August 2022, domestic production of NEV reached 3.97 million units (+1.2) and sales of 3.86 million units (an increase of a multiplication of 1.1), while the production volume in 2020 in China was 1.366 million units and sales of 1.367 million.
comparison
Currently, the impact of high raw material prices for lithium batteries has reached automakers, as well as battery manufacturers such as Catel, which has moved them to sodium-ion batteries, which have more stable electrochemical performance and lower cost compared to lithium batteries, compared to lead acid redox flow batteries.Fully Vanadium has a higher cost performance index.
While the cost of cathode materials in lithium-ion batteries is the highest (43%), it accounts for only 26% in sodium-ion batteries.
