A new type of hybrid sodium-ion battery that offers both high capacity and rapid-charging capabilities could power mobile devices, electric vehicles and space tech.
Researchers have developed a new coin-type sodium-based battery that can charge rapidly “in seconds” and could potentially power everything from smartphones to electric vehicles (EVs) in the future.
By combining anode materials used in conventional batteries with cathodes from supercapacitors — batteries that can store and deliver energy at very high rates –– the scientists created a new type of sodium-ion battery that offers both high capacity and rapid-charging capabilities.
They were looking for a way to overcome the current limitations of sodium-ion energy storage — touted as an alternative to lithium-ion batteries — and described their findings in a study published March 29 in the journal Energy Storage Materials.
The new sodium-ion hybrid fuel cells could serve as a "viable next-generation alternative to lithium-ion batteries," the researchers said in a joint statement, with applications ranging from laptops and mobile devices to electric vehicles and aerospace technologies.
Sodium is significantly more abundant than lithium –– up to 1,000 times more, the researchers said –– making sodium-ion batteries potentially cheaper and more sustainable to produce than the lithium-ion batteries currently used to power most EVs and consumer electronics.
However, existing sodium-ion batteries offer lower power output and storage capacity than lithium-ion batteries and take longer to charge, thus limiting their potential applications. In the new study, the researchers sought a way to tackle the shortcomings of the technology.

Engineers have had this battery about 5 years now and it works as advertised, .... however, they can't make it in sizes much larger than a quarter. The largest auto that you could power it with is the size of a Hot Wheels.
Maybe that's the 'plan'.....................
They are either full of crap or it’s very dangerous. Transfer of enough energy to power anything of any size for very long is going to take a lot longer than “seconds”, if the transfer is stable.
Great, but how do you extinguish them when they catch on fire?
Elemental sodium, like phosphorous, doesn’t play well with water, IIRC.
Still doesn’t answer the question of where the power is going to come from. Regardless of how fast it charges, the amount of power remains the same and in fact faster charging would put even more of a strain
You could watch television while you walk to work.
But sodium is heavier so is this really appropriate for mobile applications?
Yeah with magic electric power?????
Brown out/Blackouts
Fast charging takes wattage
Charging a vehicle which is twice as expensive, and twice as heavy, is not feasible, no matter how quickly it is accomplished.
Of course, there’s still the fire danger, but Big Brother doesn’t care.
Sizzlers! Remember those? Tesla Model Ss look suspiciously like what I remember a Sizzler car looking like.
That is what I was thinking, essentially they will be creating bombs.
It might be this one:
“Could” is meaningless in the real world.
Monkeys *could* fly out of my butt.
These guys think you could re-charge an electric vehicle in seconds? Heck, let’s give them 5 minutes. Now calculate the size of the power infrastructure needed to deliver that much energy in 5 minutes. Now let’s visualize putting it every place there is now a conventional gas station.
Hahahahahaha!
Nope. Still not buying one.
Since everything they replace something bad with turns out to be even worse, no way am I taking any chances.
Bull crap.
What’s the big deal? Current EVs recharge in seconds, already. 15000 to 16000 or so, but seconds are seconds… 🙄
