Sodium-ion batteries are set to disrupt the LDES market within the next few years, according to new research – exclusively seen by Power Technology’s sister publication Energy Monitor – by GetFocus, an AI-based analysis platform that predicts technological breakthroughs based on global patent data. Sodium-ion batteries are not only improving at a faster rate than other LDES technologies but they are also set to be cost comparable with the cheapest forms of dispatchable power, and therefore enter mainstream use, as early as 2027.
So one of the disadvantages of Lithium-Ion batteries is its reactivity and proclivity for explosions/thermal runaway.
I would imagine sodium is even more reactive, no? Might be worth the engineering/safety challenges if the storage is better/comparable, and the cost is cheaper.
For all I’ve heard, sodium batteries are actually more safe and can even be pierced or crushed with no fires/explosions occurring.
After all, they don’t use pure metallic sodium.
The sodium used is part of a compound and not pure sodium. Sodium ion batteries have been shown to be less susceptible to explosions/thermal runaway.
short answer: no
