Sodium-ion battery cost

What is a sodium ion battery?

Overall, we provide a broad and interdisciplinary perspective on modern batteries and future directions for this field, with a focus on sodium-ion batteries. Sodium-ion batteries are an appealing alternative to lithium-ion batteries because they use raw materials that are less expensive, more abundant and less toxic.

How much does sodium ion cost per kWh?

However, the second generation sodium ion could reach $40 per kWh. Iron LFP batteries could get to $50/kWh with really high volume and efficiency at the cell level. The future low price of sodium ion would make for insanely cheap fixed storage products like the Tesla Megapack and Powerwalls. They also do not have practical material limits.

Are sodium-ion batteries worth it?

Sodium itself is extremely abundant and cheap. But these batteries have lagged behind lithium-ion batteries because they have relatively low energy density — the amount of electrical energy that can be stored per unit of weight. Now CATL says its research has paid off with a new sodium-ion battery with an energy density of 160 Wh/kg.

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.

Are sodium ion batteries good?

CATL and other battery manufacturers have been researching sodium-ion batteries for several years. Lithium-ion batteries are great but need relatively expensive raw materials such as lithium, nickel, or cobalt. They also do not perform well at low temperatures, as any EV owner who lives in a cold climate can attest.

Are sodium batteries cheaper than lithium ion batteries?

Unlike lithium, sodium can be produced from an abundant material: salt. Because the raw ingredients are cheap and widely available, there’s potential for sodium-ion batteries to be significantly less expensive than their lithium-ion counterparts if more companies start making more of them.
