Are aqueous sodium ion batteries a viable energy storage option?

Nature Communications 15, Article number: 575 (2024) Cite this article Aqueous sodium-ion batteries are practically promising for large-scale energy storage, however energy density and lifespan are limited by water decomposition.

What is a sodium ion battery?

Sodium-ion batteries are a cost-effective alternative to lithium-ion batteries for energy storage. Advances in cathode and anode materials enhance SIBs' stability and performance. SIBs show promise for grid storage, renewable integration, and large-scale applications.

Why do we use sodium ion batteries in grid storage?

a) Grid Storage and Large-Scale Energy Storage. One of the most compelling reasons for using sodium-ion batteries (SIBs) in grid storage is the abundance and cost effectiveness of sodium. Sodium is the sixth most rich element in the Earth's crust, making it significantly cheaper and more sustainable than lithium.

Are sodium-ion batteries a new opportunity beyond energy storage by lithium?

Eftekhari A, Kim D-W. Sodium-ion batteries: new opportunities beyond energy storage by lithium. Journal of Power Sources. 2018;395:336–348. doi: 10.1016/j.jpowsour.2018.05.089. [Google Scholar] 20.

Are aqueous sodium ion batteries durable?

Concurrently Ni atoms are in-situ embedded into the cathode to boost the durability of batteries. Aqueous sodium-ion batteries show promise for large-scale energy storage, yet face challenges due to water decomposition, limiting their energy density and lifespan.

Why are large-scale sodium-ion batteries gaining momentum?

Large-scale sodium-ion batteries are gaining momentum due to their lower cost and abundance of raw materials compared to lithium-ion batteries. The challenges with sodium-ion batteries have been lower energy density and shorter lifespans that can limit efficiency and long-term performance in large-scale applications.
