French researchers develop sodium-ion battery in 18650 format; performance comparable to Li-ion

Green Car Congress

Researchers within the RS2E network on electrochemical energy storage (Réseau sur le stockage électrochimique de l’énergie) in France have developed the first sodium-ion battery in an 18650 format. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium.
