Are sodium-ion batteries a cost-effective energy storage solution?

Sodium-ion batteries are rapidly emerging as a promising solution for cost-effective energy storage. What Are Sodium-Ion Batteries? Sodium-ion batteries (SIBs) represent a significant shift in energy storage technology. Unlike Lithium-ion batteries, which rely on scarce lithium, SIBs use abundant sodium for the cathode material.

How much will sodium ion batteries cost in 2028?

Assuming a similar capex cost to Li-ion-based battery energy storage systems (BESS) at $300/kWh, sodium-ion batteries’ 57% improvement rate will see them increasingly more affordable than Li-ion cells, reaching around $10/kWh by 2028.

Will sodium-ion batteries dominate the future of long-duration energy storage?

With costs fast declining, sodium-ion batteries look set to dominate the future of long-duration energy storage, finds AI-based analysis that predicts technological breakthroughs based on global patent data. Sodium-ion batteries’ rapid development could see long-duration energy storage (LDES) enter mainstream use as early as 2027.

Are sodium ion batteries a good investment?

Analysing 30 LDES technologies, the research found sodium-ion batteries to hold the most promise due to their fast improvement rate – around 57% in 2024. They offer more efficiency in round-trip energy use, greater operational flexibility and lose less energy during storage and supply.

Are sodium-ion batteries a low-cost option?

Still, achieving a low-cost contender may be several years away for sodium-ion batteries and will require technological advances and favorable market conditions, according to a new study in Nature Energy. Sodium-ion batteries are often assumed to have lower costs and more resilient supply chains compared to lithium-ion batteries.

What is a sodium ion battery?

Sodium-ion batteries (SIBs) represent a significant shift in energy storage technology. Unlike Lithium-ion batteries, which rely on scarce lithium, SIBs use abundant sodium for the cathode material. Sodium is the sixth most abundant element on Earth’s crust and can be efficiently harvested from seawater.
