China has the most patents in this field
China leads in the development of innovative batteries.
An estimate of the number of patents for sodium-ion batteries shows that China surpasses Japan and the United States, and Chinese companies are expected to begin mass production of these batteries this year. They are planned to be widely used in electric vehicles.
It is expected that the cost of materials for the production of sodium-ion batteries will be reduced by 60%, since the proportion of rare earth metals is reduced in their composition.
Earlier it was reported that BYD Seagull will be the first electric car with a sodium-ion battery .
