Toyota develops new positive electrode material that is believed to increase the storage capacity of sodium-ion battery power significantly. These findings could be the basis for the development of new types of batteries that can power electric cars until the member can travel a distance of 500km - 1000km every time you refill the batteries.
According to a report in The Nikkei, battery prototype has been made. Size as coins and serve at room temperature (27 degrees Celsius) and can generate an electric voltage 30% higher than Lithium-ion batteries.
The basic ingredients Lithium-ion battery Lithium metal is a rare and expensive. Sodium-ion battery while the basic material is abundant, it is estimated that the price could be reduced later. Toyota believes that electric cars popular, mininal distance of 500km/refill. This research is expected to be completed in 2020. At that time, sodium batteries have entered the commercial stage.
