Price of sodium sulfur energy storage battery

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.

What is a sodium-sulfur battery?

The team’s design makes use of carbon-based electrodes and a thermal degradation process known as pyrolysis to alter the reactions between the sulfur and sodium. 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.

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.”

Can a sodium battery reduce energy costs?

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. “Our sodium battery has the potential to dramatically reduce costs while providing four times as much storage capacity.

Are room-temperature sodium sulfur batteries suitable for grid scale stationary energy storage?

Room-temperature sodium sulfur (RT-Na/S) batteries possess high potential for grid scale stationary energy storage due to their low cost and high energy density.

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.
