# Sodium-ion Batteries Show Similarities with Lithium-ion Counterparts

Despite being touted as a promising alternative, sodium-ion batteries have similarities in operation to their lithium-ion counterparts, involving the movement of charged particles between electrodes.

Sodium-ion batteries are making waves in the industry, but they're not as different from lithium-ion batteries as one might think.

The basic principle behind both battery types is similar: charged particles move between negative and positive electrodes to store and release energy. This process involves ions, which are atoms or molecules that have gained or lost electrons, resulting in a charge.

Lithium-ion batteries work by moving lithium ions from the negative electrode to its positive counterpart, whereas sodium-ion batteries do the same with sodium ions. The key difference between these two battery types lies not in how they operate, but rather in their composition and the elements that supply the ions.

Energy density is another area where sodium-ion batteries fall short compared to lithium-ion cells. Sodium-ion cells can store around 175 watt-hours per kilogram, which is roughly 20 to 30 percent lower than what lithium-ion cells achieve.

Lithium-ion phosphate and lithium NMC (nickel manganese cobalt oxide) have managed to push energy density even higher, reaching 205 and 255 watt-hours per kilogram respectively. This disparity in energy storage capacity raises important questions about the practicality of sodium-ion batteries.

The widespread availability of sodium has been touted as one of its major advantages over lithium-ion batteries. However, this abundance has yet to translate into mass production, and lithium has a significant head start in terms of production and use.

While the term "abundance" might be misleading when it comes to sodium's availability, it is indeed widely distributed. Nevertheless, sourcing other essential components such as nickel and manganese remains a challenge for manufacturers like JAC Motors, which has developed a sodium-ion battery for its 2024 electric vehicle.

Sodium-ion batteries have shown an advantage over lithium-ion alternatives in cold weather performance. According to the International Energy Agency (IEA), sodium-ion batteries retain up to 90% of their capacity at minus 40 degrees Fahrenheit, outperforming lithium-ion batteries that suffer a significant loss of capacity under similar conditions.

The inherent stability of sodium-ion batteries has also been observed in their lower risk of thermal runaway. These cells generate less heat and require fewer protection systems than their lithium-ion counterparts, which could indicate greater safety in the event of an accident.

While sodium-ion batteries exhibit some promising characteristics, their limitations in terms of energy storage capacity remain a concern. This disparity raises important questions about the practicality of sodium-ion batteries as a viable alternative to established technologies like lithium-ion batteries.

The transition to sodium-ion batteries is already underway, with companies like CATL and GMC at the forefront of this shift. Alongside them, other firms such as HiNa Battery Technology and Natron Energy are also exploring the potential of sodium-ion technology.

However, for sodium-ion to truly compete with lithium-ion batteries, it needs more applications beyond automotive use cases. One promising area is stationary storage, where battery installations can support the electric grid without being constrained by the size and weight limitations that EVs face.

The analogy of Betamax versus VHS comes to mind in this context. Just as VHS had the scale and consumer lock-in that ultimately led to its dominance, lithium-ion batteries have established manufacturing processes and robust supply chains that give them a significant advantage over sodium-ion batteries.

In the end, the success of sodium-ion technology may depend on its ability to fill gaps that lithium-ion batteries cannot address. By focusing on specific use cases such as extreme cold weather or hybrid packs, sodium-ion could carve out a niche for itself in the market and offer customers more choices.
