Sodium-ion batteries: The future of energy storage?

At DMS technologies, we’ve spent decades at the forefront of battery innovation – designing, manufacturing and integrating power solutions that meet the most demanding applications. Now, with growing global interest in sustainable energy systems, sodium-ion batteries (SIBs) are emerging as one of the most exciting developments in the energy storage space.

Could this be the next big leap forward?

Why sodium-ion is gaining momentum:

1. Abundant and low-cost materials

Unlike lithium, sodium is readily available and inexpensive to source. It can be extracted from seawater or mined more sustainably, making it a viable long-term solution to reduce reliance on critical raw materials like lithium, cobalt and nickel.

2. Ideal for stationary storage

Although sodium-ion batteries don’t match lithium-ion in energy density, they offer distinct benefits for applications where space and weight are less critical – such as grid-scale storage, renewable integration, telecoms and back-up power systems. This makes them a perfect fit for many of the sectors DMS technologies already serves.

3. Safer chemistry

SIBs generally have a lower risk of thermal runaway and are more stable at high temperatures, reducing the need for complex battery management and cooling systems.

4. Cold weather performance

Unlike many lithium chemistries, sodium-ion batteries perform reliably in colder temperatures – making them well-suited to remote or harsh environments where resilience is key.

Limitations to be aware of

It’s important to note that sodium-ion technology is still maturing. The energy density is currently lower than lithium-based alternatives, which limits its effectiveness for high-performance electric vehicles. Additionally, large-scale commercialisation is only just beginning, and supply chains are still developing.

But with global players accelerating production and investment, these challenges are being rapidly addressed.

A strategic opportunity for the UK

The UK is at the forefront of sodium-ion battery innovation, with companies investing in scalable, homegrown production. Government support and a shift toward energy resilience make this an ideal time to explore new battery solutions.

Looking ahead

Sodium-ion batteries are not here to replace lithium-ion across the board – but they’re an exciting complement, especially in the context of renewable energy, backup systems and industrial power storage.

As always, DMS technologies will continue to evaluate the latest developments, work with trusted partners and offer energy solutions that meet evolving customer needs. Sodium-ion may not be the only future of battery storage, but it’s one we’re watching closely.
