In the pursuit of greener energy solutions, Northvolt, a Swedish company, has quietly achieved a groundbreaking feat in sodium-ion battery technology. Boasting an energy density of up to 160 Wh/kg, this breakthrough positions Northvolt as a game-changer in the evolving landscape of affordable and high-density energy storage.

Northvolt’s sodium-ion battery overview:

What’s New?

This breakthrough propels sodium-ion batteries into the spotlight, challenging the dominance of Lithium Iron Phosphate (LFP) cells. Northvolt’s sodium-ion battery matches the energy density of LFP counterparts commonly found in less expensive electric vehicles (EVs). While falling slightly short of the higher-end Nickel Manganese Cobalt (NMC) batteries, the Prussian-White cathode material emerges as the catalyst behind this advancement.

The chemistry behind it

Sodium ion battery chemistry

The specifics of Northvolt’s sodium-ion battery unveil state-of-art chemistry. With a cathode crafted from Prussian-White—free from cobalt, lithium, graphite, and nickel—coupled with a hard carbon anode, this technology achieves a unique balance. Boasting better cost-effectiveness than both NMC and LFP batteries, it positions itself as a frontrunner in the pursuit of efficient, affordable, and safe energy storage.

How safe is it?

The company claims a pivotal advantage: the safety of Northvolt’s sodium-ion battery technology across temperature variations. Unlike its counterparts, both NMC and LFP batteries, this breakthrough ensures stability, aligning density, affordability, and safety in an unprecedented manner.

What’s next for Northvolt?

Northvolt has made a breakthrough with the improved Na-ion battery, but this is just the beginning of their journey. The company is now preparing to enter production and plans to focus on pouch cells for stationary storage. This strategic move is aimed at addressing the immediate need for reliable and safe energy solutions.

Local Production in action


The key to success lies in the details, specifically the Prussian-White cathode and hard carbon anode. These elements not only contribute to breakthrough performance but enable local production with locally sourced materials.

Beyond technological prowess, Northvolt’s sodium-ion battery chemistry finds practical applications in warmer climates. Considered ideal for regions like the Middle East and Africa, the breakthrough extends its impact beyond laboratories, promising practical solutions for diverse environments.
