A team of scientists in France have taken a major step towards powering the devices that maybe much faster and cheaper than the current lithium batteries we use today. For the first time ever, a battery has been developed using sodium ions in the industry standard “18650” format used in laptop batteries, LED flashlights and the Tesla Model S, among other products. The team is planning to make cheap sodium ion batteries that can be used for a wide variety of purpose by the users. The lithium ions in lithium-ion batteries, sodium ions travel from one electrode to another through liquid during charging and use cycles without modifying the materials in the battery.
The researchers are keeping those specific materials a trade secret for now, but the performance of the prototype battery is promising. The Lithium had an advantage of being lighter and provides more energy, but the team is hoping to use the sodium ion battery across the European Markets for a variety of applications.
