Today's cellphones use lithium batteries for power. Sodium could be a better option for batteries than lithium, according to researchers—but there's a problem.Current technology stores lithium ions in graphite (a soft mineral made of carbon), but sodium ions are too big to be stored in graphite.
Sodium is better than lithium in a lot of ways. It's much cleaner than lithium, which contributes heavily to climate change and pollution. Because of its abundance, sodium is also cheaper than lithium, which must be mined.And you can't line the top of your margarita glass with lithium."Imagine being able to walk right up to the ocean just a few miles from here," said Liu, "and get all the salt you need to manufacture all the world's cellphone batteries."To the delight of smartphone addicts, Zhou's sodium-ion battery can be charged to 50 percent capacity in just two minutes. But don't rush out to buy it yet.
The next step for Zhou and his team is to improve the performance and life of their battery so they can bring it to market.

Sodium batteries have its own advantages but don’t think it’s ideal for electric vehicles.
Toyota, Tesla, VW....... why are they choosing lithium batteries???
