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 be more common in low-cost EVs?

He expects that sodium-ion batteries will be more common in low-cost EVs for people who live in cities or suburbs and don’t place a high premium on driving range. “It will not be a fringe player,” he said, about sodium-ion.

Are sodium ion batteries better than lithium-ion?

But sodium-ion batteries have some disadvantages. The big one is low energy density compared to lithium-ion. As a result, an EV running on a sodium-ion battery will go fewer miles per charge than a lithium-ion battery of the same size. “That is just what nature has given us,” Srinivasan said.

How much energy does a sodium ion battery use?

A typical sodium-ion battery has an energy density of about 150 watt-hours per kilogram at the cell level, he said. Lithium-ion batteries can range from about 180 to nearly 300 watt-hours per kilogram. I asked Srinivasan what he makes of CATL’s claim of a sodium-ion battery with 200 watt-hours per kilogram.

Will China lead the way in sodium-ion battery production?

Although the companies are yet to commercialise their technologies, Chinese battery company Great Power last year announced a 50MW/100 megawatt-hour LDES project to power a data centre, demonstrating that sodium-ion batteries are already under consideration for LDES. “China will probably lead the way for sodium-ion battery production,” adds Gorski.

What are the disadvantages of sodium ion batteries?

The process of manufacturing sodium-ion batteries is similar to that of lithium-ion batteries, or at least similar enough that companies can shift existing assembly lines without having to spend heavily on retooling. But sodium-ion batteries have some disadvantages. The big one is low energy density compared to lithium-ion.
