Is a sodium-sulfur battery the future of energy storage?

The group’s novel sodium-sulfur battery design offers a fourfold increase on energy capacity compared to a typical lithium-ion battery, and shapes as a promising technology for future grid-scale energy storage.

Can sodium sulfur batteries be used in cars?

Perhaps sodium sulfur batteries will not be appropriate for use in automobiles, but the world is going to need energy storage options for large EV charging stations and grid scale storage to help make renewable energy dispatchable so we can close more gas-fired peaker plants and coal-fired baseload generating stations.

Are sodium & sulfur a good material for battery production?

Sodium and sulfur stand out as appealing materials for future battery production because they are cheaper and more widely available than materials such as lithium and cobalt, which also have environmental and human rights concerns.

Is a sodium sulfur battery better than a lithium ion battery?

They claim the sodium sulfur battery is a more energy dense and less toxic alternative to lithium ion-batteries. In a press release, Zhao says the battery has been specifically designed to provide a high performing solution for large renewable energy storage systems such as electrical grids while significantly reducing operational costs.

What is the capacity of a sodium-sulfur battery?

The result is a sodium-sulfur battery with a high capacity of 1,017 mAh g−1 at room temperature, which the team notes is around four times that of a lithium-ion battery. Importantly, the battery demonstrated good stability and retained around half of this capacity after 1,000 cycles, described in the team’s paper as “unprecedented.”
