WHAT IS IT?
Sodium-ion batteries have a similar design to lithium-ion counterparts and can be manufactured using related methods. Both battery types generate electricity through a chemical reaction and comprise an anode, cathode, separator, and electrolyte.
WHY IMPORTANT
Sodium-ion batteries can’t provide the type of range for electric vehicles offered by lithium-ion batteries, but they present some unique advantages. For instance, the materials used in sodium-ion batteries tend to be cheaper than those in lithium-ion batteries. There’s no cobalt, there’s no copper, there’s no lithium, there’s no graphite, which is primarily controlled by China today.”
And sodium-ion batteries are also safer since they can be discharged entirely for transportation.
