Sodium in batteries for electric vehicles!

The sodium-ion battery promises many advantages such as the fact that it is non-flammable, inexpensive, but above all that the materials necessary for its design are easily and abundantly available. Its only current major flaw is its limited lifespan.

But a research team from the United States Department of Energy at the Pacific Northwest National Laboratory has developed a sodium-ion battery with very long life. The secret comes from the new electrolyte used which is capable of generating a protective layer on the anode and on the cathode.

Thanks to this protection, the authorized number of cycles thus increases to 300 and the loss of capacity remains at the same time below 10%. Last advantage, the battery is able to withstand high temperatures. It could soon compete with lithium-ion batteries to equip your electric bikes or even your car.
