Reference News website, August 5 report: According to the "Nikkei Business Publications", sodium-ion batteries using sodium abundant in the ocean have been officially mass-produced in China.
The report said that due to the trend of decarbonization, sodium-ion batteries began to be commercialized around 2021. Compared with lithium-ion batteries, its energy density is lower, but it is safer. According to data from Fujikura Economic Research Company, the sodium-ion battery market size was about 6 billion yen (100 yen is approximately 4.9 Chinese yuan - this site note) in 2024, and it could increase to 1.3 trillion yen by 2045.
The report said that Chinese enterprises are leading in the research and commercialization of sodium-ion batteries. Chinese major automobile company BYD started mass production of sodium-ion batteries in 2024, and industry giant CATL also announced that it will launch a new brand and start commercialization of sodium-ion batteries in 2025.
In contrast to this trend, Japanese battery manufacturers have not taken any obvious actions. Japan's Electric Nitro Corporation has only produced a small sample of "all-solid-state sodium-ion battery". Sumitomo Electric Industries originally planned to bring out a product around ten years ago, but later stopped development.
The report said that the production efficiency of sodium-ion batteries just starting mass production is still very low, and the price is higher compared to lithium-ion batteries. However, if the mass production of sodium-ion batteries makes progress, it is almost certain that the price will be lower than that of lithium-ion batteries.
The report said that by making full use of the revenue and users obtained from the mass production of sodium-ion batteries, Chinese enterprises may gain a leading position in the market over Japanese enterprises. (Translated by Liu Jieqiu)
