Energy storage systems come in many forms, leveraging different technology types. A class of electrochemical storage, lithium-ion batteries have established themselves as the industry standard.

But there are many new technologies vying for their market share.

Sodium-ion batteries are widely considered a sustainable and resource-saving answer to future energy storage, while flow batteries offer a viable alternative in long-duration storage applications.
However, the path to commercialization is not a straightforward one.

Comparing thermal runaway behavior of sodium-ion, lithium-ion batteries Scientists in Germany have analyzed the thermal runaway behavior of sodium-ion batteries and lithium-ion batteries inside a 10-L reaction vessel. They have thermally abused 30 samples, each under a different state of charge level, and have found that both types suffered from runaway when the charge is at least 50%.
